Description

Die Erfindung betrifft eine Vorrichtung zur Entfeuchtung und/oder Entsalzung von Bauwerken durch Schwingungsbeaufschlagung mit einer dem Bauwerk zugeordneten, wenigstens eine Spule enthaltenden Sendeeinrichtung, die mit einem von einer Signalerzeugungseinrichtung kommenden, eine hochfrequente Schwingung mit einer Frequenz im Bereich von 141 kHz ausführenden Spannungssignal beaufschlagbar ist und entsprechende Schwingungen aussendet.The invention relates to a device for dehumidifying and / or Desalination of structures by vibration with a building assigned to the at least one coil containing transmitting device with one of a Signal generating device coming, a high-frequency Oscillation with a frequency in the range of 141 kHz exporting voltage signal can be acted upon and emits appropriate vibrations.

Eine Vorrichtung dieser Art ist aus der EP 0 736 639 A1 bekannt. Bei dieser bekannten Anordnung wird das der Sendeeinrichtung zugeführte Signal nicht verstärkt. Es ergibt sich daher eine vergleichsweise kleine Sendeleistung. Die bekannte Anordnung kann daher nur mit Luftwellen arbeiten. Eine direkte Einleitung der ausgesandten Schwingungen in das Bauwerk ist nicht möglich. Die erzielbare Sanierungsgeschwindigkeit ist daher vergleichsweise gering.A device of this kind is known from EP 0 736 639 A1. In this known arrangement that of the transmitting device supplied signal not amplified. It therefore arises a comparatively low transmission power. The known arrangement can therefore only work with air waves. A direct introduction the emitted vibrations in the building is not possible. The achievable rehabilitation rate is therefore comparatively low.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Vorrichtung eingangs erwähnter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß vergleichsweise schnell eine hohe Sanierungswirkung erreichbar ist.On this basis, it is therefore the object of the present invention Invention, a device of the kind mentioned with simple and cost-effective means to improve so that comparatively quickly a high renovation effect is achievable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Sendeeinrichtung eine Verstärkungseinrichtung zur Verstärkung des von der Signalerzeugungseinrichtung kommenden Signals zugeordnet ist und daß die Sendeeinrichtung zumindest eine mit dem Bauwerk körperlich verbindbare Antenne aufweist.This object is achieved in that the Transmitting means an amplifying means for amplification the signal coming from the signal generating means is assigned and that the transmitting device with at least one the structure has physically connectable antenna.

Mit diesen Maßnahmen werden in vorteilhafter Weise die geschilderten Nachteile des Standes der Technik vollständig beseitigt. Die körperliche Verbindung der Antenne mit dem Bauwerk führt zu einer direkten Anregung der Feuchtigkeitsteilchen bzw. der in der Feuchtigkeit enthaltenen, aus gelösten Salzen resultierenden Ionen, an denen sich Feuchtigkeit anlagert. In Folge der Signalverstärkung ergibt sich die hierfür erforderliche Sendeleistung. Zur Bildung der Verstärkungseinrichtung kann ein einfacher Radioverstärker mit einer den Frequenzbereich von 141 kHz umfassenden Bandbreite vorgesehen sein. Dies wirkt sich vorteilhaft auf die Vermeidung von Bauaufwand aus und ergibt gleichzeitig eine einfache Einstellbarkeit.These measures are advantageously the described disadvantages of the prior art completely eliminated. The physical connection of the antenna with the Bauwerk leads to a direct suggestion of the Moisture particles or contained in the moisture, from dissolved salts resulting ions, which cause moisture attaches. As a result of the signal amplification, this is the result required transmission power. To form the Amplifier can be a simple radio amplifier with a bandwidth covering the frequency range of 141 kHz be provided. This has an advantageous effect on the avoidance of Construction costs and at the same time results in a simple Adjustability.

Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben. Dadurch, daß die Verstärkungseinrichtung regelbar ist, läßt sich die Sendeleistung auf einfache Weise an die vorgefundene Mauerstärke etc. anpassen. Advantageous embodiments and expedient further developments of Parent measures are in the subclaims specified. Characterized in that the amplifying device is adjustable, can the transmission power in a simple manner to the found Adjust wall thickness etc.

Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß der körperlich mit dem Bauwerk verbindbaren Antenne eine elektrische Isolierung gegenüber dem Bauwerk zugeordnet ist. Hierdurch ist sichergestellt, daß kein Strom in das Mauerwerk eingeleitet wird, das auf Grund der Feuchtigkeit einen vergleichsweise kleinen Widerstand aufweist. Ein Potentialgefälle zwischen dem im Mauerwerk vorhandenen Erdpotential und einer außerhalb des Mauerwerks eventuell geschaffenen Potentialsenke wird daher nicht gestört. Zweckmäßig kann die isolierte Antenne in eine Isolierhülse eingegossen sein. Dies ergibt in vorteilhafter Weise eine stabförmige Anordnung, die in eine zugeordnete Bohrung im Mauerwerk eingesetzt werden kann und mittels einer Kontaktpaste in satte Verbindung mit dem Mauerwerk gebracht werden kann.A further advantageous measure may be that the physically connectable to the building an antenna electrical insulation is assigned to the building. This ensures that no electricity in the masonry that is due to the humidity one has comparatively small resistance. A potential gradient between the earth potential present in the masonry and a outside of the masonry possibly created potential sink is therefore not disturbed. Conveniently, the isolated antenna in be poured an insulating sleeve. This results in an advantageous manner a rod-shaped arrangement, which in an associated hole in Masonry can be used and by means of a contact paste can be brought into full connection with the masonry.

In weiterer Fortbildung der übergeordneten Maßnahmen kann die körperlich mit dem Mauerwerk verbindbare Antenne einen Tragkern aufweisen, auf den eine Hochfrequenzlize aufgewickelt ist. Dies ergibt eine besonders einfache und robuste Bauweise. Die Hochfrequenzlize kann dabei mit einer Isolierung versehen sein, wodurch sich automatisch die gewünschte Isolierung gegenüber dem Bauwerk ergibt und eine zusätzliche Isolierung entfallen kann. Die Hochfrequenzlize ist dabei zweckmäßig mit einem Ende an die Spule der Sendeeinrichtung und mit dem anderen Ende an das Gerätepotential der Sendeeinrichtung angeschlossen, so daß der in der Spule induzierte Strom fließen kann.In further training of the parent measures, the physically connectable to the masonry antenna one Have support core, wound on a Hochfrequenzlize is. This results in a particularly simple and robust construction. The Hochfrequenzlize can be provided with an insulation, which automatically opposite to the desired insulation the structure results and an additional insulation accounts can. The Hochfrequenzlize is expedient with one end to the coil of the transmitting device and to the other end connected the device potential of the transmitting device, so that the current induced in the coil can flow.

Eine weitere zweckmäßige Maßnahme kann darin bestehen, daß der Tragkern als Ferritkern ausgebildet ist. Hierdurch ist sichergestellt, daß bereits mit einer vergleichsweise kleinen Windungszahl eine vergleichsweise hohe Abstrahlung erreicht wird. Another expedient measure may be that the support core is designed as a ferrite core. This is ensured that even with a comparatively small Winding a comparatively high radiation is achieved.

Sofern die Sendeeinrichtung mehrere Antennen aufweist, von denen wenigstens eine als Freiluftantenne und wenigstens eine als körperlich mit dem Bauwerk verbindbare Antenne ausgebildet ist, ist es besonders zu bevorzugen, wenn die Spule eine der körperlich mit dem Bauwerk verbindbaren Antenne zugeordnete Mittelanzapfung aufweist.If the transmitting device has a plurality of antennas, from which at least one as an outdoor antenna and at least one as physically connectable to the building antenna is formed It is especially preferable if the coil is one of the most physical associated with the building connectable antenna Center tap has.

Vorteilhaft können mehrere bauwerkseitige Antennen vorgesehen sein, die parallel geschaltet sind. Hierdurch läßt sich eine besonders gleichmäßige Schwingungsbeaufschlagung auch größerer Bauwerke erreichen.Advantageously, a plurality of building-side antennas can be provided be connected in parallel. This can be a particularly even vibration exposure, too reach larger structures.

In weiterer Fortbildung der übergeordneten Maßnahmen kann der Signalerzeugungseinrichtung ein Netzteil mit vorgeordnetem Netztrafo zugeordnet sein, wobei das Netzteil zwei Gleichstromausgänge für Plus und Minus aufweist, über welche die Signalerzeugungseinrichtung, die Vestärkungseinrichtung und die Sendeeinrichtung mit Plus- und Minus-Spannung versorgbar sind. Hierbei entfällt in vorteilhafter Weise ein eigener Masseanschluß der genannten Aggregate, wodurch sich eine Leistungssteigerung der dortigen Operationsverstärker ergibt.In further training of the superordinate measures of the Signal generating device a power supply with upstream Power transformer to be assigned, with the power supply two DC outputs for plus and minus has over which the signal generating device, the reinforcing device and the transmitter can be supplied with positive and negative voltage are. This eliminates advantageously a separate Ground connection of said aggregates, resulting in a Performance increase of the local operational amplifier results.

Gemäß einer weiteren vorteilhaften Ausgestaltung kann vorgesehen sein, daß die zwei Gleichstromausgänge des Netzteils zur Bildung einer Potentialsenke gegenüber dem im Bauwerk vorhandenen Potential wahlweise mit einem zumindest in der Nähe des Bauwerks in die Erde einbringbaren Leiter verbindbar sind. Hierdurch läßt sich in vorteilhafter Weise eine zum Leiter hin gerichtete Ionenwanderung erreichen, die durch die Schwingungsbeaufschlagung unterstützt und beschleunigt wird, so daß sich im Zusammenwirken der genannten Maßnahmen schon in vergleichsweise kurzer Zeit ein hoher Sanierungseffekt erreichen läßt.According to a further advantageous embodiment can be provided that the two DC outputs of the power supply for the formation of a potential sink in relation to that in the building existing potential optionally with one at least in the vicinity of the structure can be connected in the earth introducible ladder. As a result, can be advantageously to the ladder out to achieve directional ion migration through the Vibration is supported and accelerated, so that in the interaction of these measures already achieve a high renovation effect in a relatively short time leaves.

Weitere vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben und aus der nachstehenden Beispielsbeschreibung anhand der Zeichnung näher entnehmbar.Further advantageous embodiments and expedient Trainings of the superordinate measures are in the rest of subclaims and from the following example description with reference to the drawing closer removable.

In the drawing described below:
FIG. 1
a block diagram of a device according to the invention and
FIG. 2
an enlarged view of a transmitting device according to the invention.

Die der Figur 1 zugrundeliegende Vorrichtung dient zum Entfeuchten und/oder Entsalzen von zum Beispiel durch aufgestiegene Erdfeuchtigkeit feuchtem Mauerwerk von Bauwerken jeder Art, beispielsweise Gebäuden und Gebäudeteilen. Ein entsprechendes Gebäude ist durch eine Wand 1 angedeutet.The figure 1 underlying device is used for Dehumidify and / or desalting, for example, by Ascended earth moisture damp masonry of buildings any kind, such as buildings and parts of buildings. On corresponding building is indicated by a wall 1.

Mit Hilfe der erfindungsgemäßen Vorrichtung wird eine elektromagnetische Schwingung 2 ausgesandt, mit welcher die Wand 1 beaufschlagt wird. Hierbei handelt es sich um eine hochfrequente Schwingung im Langwellenbereich mit einer Frequenz im Bereich von 141 kHz, vorzugsweise exakt 141 kHz. With the aid of the device according to the invention is a emitted electromagnetic vibration 2, with which the Wall 1 is acted upon. This is a high-frequency oscillation in the long-wave range with a Frequency in the range of 141 kHz, preferably exactly 141 kHz.

Zweckmäßig wird die hochfrequente Schwingung in Form einer periodischen Folge von unterschiedlich langen Schwingungssequenzen mit exponentiell abfallender Amplitude und periodisch sich änderndem Schwingungsniveau ausgesandt. Gleichzeitig wird im Umgebungsbereich der Wand 1 eine Potentialsenke errichtet, wodurch ein Potentialgefälle zwischen dem in der Wand 1 vorhandenen Erdpotential und der Potentialsenke entsteht, wie durch die Pfeile 3 angedeutet ist.Appropriately, the high-frequency oscillation in the form of a periodic sequence of different lengths Vibration sequences with exponentially decreasing amplitude and emitted periodically to varying levels of vibration. At the same time in the surrounding area of the wall 1 a Potential sink built, creating a potential difference between the existing in the wall 1 earth potential and the Potential well arises, as indicated by the arrows 3.

In der in der Wand 1 vorhandenen Feuchtigkeit sind normalerweise Salze gelöst, so daß sich Ionen ergeben, von denen diejenigen, die eine geeignete Ladung aufweisen, von der Potentialsenke angezogen werden. An den Ionen lagert sich Feuchtigkeit in Form einer Hydrathülle an, die mit den Ionen abtransportiert wird. Durch die Schwingung 2 werden die in der Wand 1 enthaltenen Feuchtigkeitsteilchen bzw. Ionen mit Hydrathülle zum Abwandern angeregt und angeschoben. Die der Potentialsenke zustrebende, gerichtete Ionenbewegung wird durch die Schwingung 2 unterstützt und beschleunigt, so daß sich insgesamt eine gute Entfeuchtungs- und Entsalzungswirkung ergibt.In the existing moisture in the wall 1 are normally salts are dissolved to give ions, of which those having a suitable charge from the Potential sink are attracted. The ions are deposited on the ions Moisture in the form of a hydrate shell, with the ions is transported away. By the vibration 2 are in the Wall 1 contained moisture particles or ions with Hydration shell stimulated to migrate and pushed. The the Potential sink aspiring, directed ion motion is through the vibration 2 supports and accelerates, so that Overall, a good dehumidifying and desalination effect results.

Zur Erzeugung der Potentialsenke 3 ist ein vorzugsweise außerhalb des jeweils zu entfeuchtenden Gebäudes in einem Abstand von mindestens einem Meter hiervon in die Erde eingebrachter, zweckmäßig als lotrecht eingeschlagener Erdspieß 4 ausgebildeter, aus elektrisch leitendem Material, vorzugsweise nichtrostendem Stahl bestehender Leiter vorgesehen, der mit einer geeigneten Spannung beaufschlagt wird. Da technisch gesehen der Stromfluß von Minus nach Plus gerichtet ist, wird der Erdspieß 4 bei einem in der Wand 1 vorhandenen Plus-Erdpotential mit noch höherer Plus-Spannung und bei Minus-Erdpotential mit noch stärkerer Minus-Spannnung beaufschlagt. Im einen Fall fungiert der Erdspieß 4 als Anode, zu der die Anionen wandern, im anderen Fall als Kathode, zu der die Kationen wandern. Die maximale Spannungsbeaufschlaugng des Erdspießes 4 beträgt zweckmäßig 15 Volt. Hierdurch ist sichergestellt, daß Sicherheitsschalter einer im zu entfeuchtenden Bauwerk vorhandenen Elektroinstallation hierauf nicht ansprechen.To generate the potential well 3 is preferably outside each to be dehumidified building at a distance of at least one meter of it buried in the earth, expediently designed as a vertically ground spike 4 trained, made of electrically conductive material, preferably stainless Steel existing conductor provided with a suitable Voltage is applied. Since technically the current flow directed from minus to plus, the ground spike 4 at a in the wall 1 existing plus ground potential with even higher positive voltage and at minus ground potential with even greater minus voltage applied. In one case, the ground spike 4 acts as Anode to which the anions migrate, in the other case as a cathode, to which the cations migrate. The maximal Spannungsbeaufschlaugng the ground spike 4 is appropriate 15 volts. This ensures that safety switch a in the building to be dehumidified electrical installation do not respond to this.

Zur Schwingungsbeaufschlagung der Wand 1 ist eine Sendeeinrichtung 5 vorgesehen, die mit einem hochfrequenten Spannungssignal beaufschlagt wird, das in einer vorgeordneten Signalerzeugungseinrichtung 6 erzeugt und in einer dieser nachgeordneten Verstärkungseinrichtung 7 verstärkt wird. Die Signalerzeugungseinrichtung 6 enthält hier einen Oszillator 8 und eine diesem nachgeordnete Anordnung zur Modulation und Pulsung des erzeugten hochfrequenten Signals. Dieses wird zweckmäßig so geformt, daß sich die oben bereits erwähnte periodische Folge unterschiedlich langer Schwingungssequenzen mit exponentiell abklingender Amplitude ergeben. Zusätzlich kann das Spannungsniveau mit jeder Periode nach oben bzw. unten verschoben werden.For vibration of the wall 1 is a Transmitter 5 is provided, which with a high-frequency Voltage signal is applied, in an upstream Signal generating device 6 generates and in one of these downstream amplification device 7 is amplified. The Signal generating device 6 here contains an oscillator 8 and a subordinate arrangement for modulation and Pulsation of the generated high-frequency signal. This will suitably shaped so that the above already mentioned periodic sequence of different lengths of oscillation sequences with exponentially decaying amplitude. In addition, can the voltage level with each period up or down be moved.

Sämtliche Aggregate der erfindungsgemäßen Vorrichtung, hier der Erdspieß 4, die Sendeeinrichtung 5, die Signalerzeugungseinrichtung 6 und die Verstärkungseinrichtung 7 werden durch ein Netzteil 9 mit vorgeordnetem Netztrafo 10 mit der benötigten Betriebsspannung versorgt. Die Signalerzeugungseinrichtung 6 erhält hierüber gleichzeitig auch die Netzfrequenz, wie durch die Signalleitung 11 angedeutet ist. Der Netztrafo 10 ist so ausgebildet, daß seine Ausgänge galvanisch vom Netz getrennt und dementsprechend hierüber nicht geerdet sind. Das Netzteil 9 enthält einen Gleichrichter, dem auf der Gleichstromseite zwei Festspannungsregler 12, 13 zugeordnet sind, von denen einer eine Plus-Spannung und einer eine Minus-Spannung erzeugt. Die Festspannungsregler 12, 13 sind auf die oben erwähnten ± 15 Volt eingestellt. Das Netzteil 9 enthält somit zwei Gleichspannungsausgänge für Plus-Spannung und Minus-Spannung wie durch die Zeichen ± angedeutet ist.All units of the device according to the invention, here the Ground spike 4, the transmitting device 5, the signal generating device 6 and the amplifying device 7 be by a power supply 9 with upstream power transformer 10 with the required operating voltage supplied. The signal generating device At the same time, 6 receives the Mains frequency, as indicated by the signal line 11. Of the Power transformer 10 is designed so that its outputs galvanically from Network disconnected and accordingly are not grounded on this. The power supply 9 includes a rectifier, which on the DC side two fixed voltage regulator 12, 13 are assigned, one of which is a plus voltage and a minus voltage generated. The fixed voltage regulator 12, 13 are on the set above ± 15 volts. The power supply 9 thus contains two DC voltage outputs for plus voltage and minus voltage as indicated by the signs ±.

Der Erdspieß 4 wird wahlweise mit einem der beiden Gleichspannungsausgänge 12, 13 verbunden. Hierzu ist ein der zum Erdspieß 4 führenden Leitung 14 zugeordneter Umschalter 15 vorgesehen. Dieser ist hier in einen Potentialregler 16 zur Einstellung des dem Erdspieß 4 zugeführten Potentials integriert. Die Sendeeinrichtung 5, die Signalerzeugungseinrichtung 6 und die Verstärkungseinrichtung 7 werden vom Netzteil 9 mit Plusund Minus-Spannung versorgt, wodurch sich ein eigener Masseanschluß dieser Aggregate erübrigt und dementsprechend eine Leistungssteigerung der dortigen Operationsverstärker erzielbar ist.The earth spike 4 is either with one of the two DC voltage outputs 12, 13 connected. This is one of to the ground spike 4 leading line 14 associated switch 15th intended. This is here in a potential controller 16 for Adjustment of the Erdspieß 4 supplied potential integrated. The transmitting device 5, the signal generating device 6 and the amplifying device 7 are the power supply 9 with Plusund Supplied minus voltage, creating its own Ground connection of these units is unnecessary and accordingly an increase in performance of the local operational amplifier is achievable.

Die Einstellung der Aggregate der erfindungsgemäßen Vorrichtung kann manuell erfolgen. Im dargestellten Beispiel ist hierzu eine Steuereinrichtung 17 vorgesehen, welche die notwendigen Einund Nachstellungen automatisch durchführt. Die Steuereinrichtung 17 wird mit im Bereich der Wand 1 gemessenen Ist-Werten des Erdpotentials, der Feuchtigkeit, der Schwingungsbeaufschlagung, des Stromflusses und dergleichen versorgt, wie durch die Signalleitungen 18 angedeutet ist, die zu zugeordneten Meßstiften 19 führen, die in die Wand 1 eingesetzt sein können. Die Meßstifte 19 bestehen wie der Erdspieß 4 zweckmäßig aus elektrisch leitendem, nichtrostendem Material, vorzugsweise nichtrostendem Stahl.The adjustment of the aggregates of the device according to the invention can be done manually.

Die Spulenanordnung 22 besitzt zwei Ausgänge in Form einer so genannten Mittelanzapfung 23 und eines Endausgangs 24. An beide Ausgänge sind Antennen angeschlossen. An den Endausgang 24 ist eine Freiluftantenne 25 angeschlossen, der eine Schutzeinrichtung 26, die einen Kondensator und einen Widerstand enthalten kann, vorgeordnet sein kann. An die Mittelanzapfung 23 ist eine in körperlichen Kontakt mit der Wand 1 bringbare Kontaktantenne 27 angeschlossen, der eine Schutzeinrichtung 28, hier in Form einer Schutzdiode, vorgeordnet sein kann.The transmission device 5 has a coil arrangement 22 on which the high frequency and amplified voltage signal is applied. The coil assembly 22 has two outputs in the form of one center tap 23 and a final exit 24. An both outputs are antennas connected. At the final exit 24 is connected to an outdoor antenna 25, which has a Protective device 26, which has a capacitor and a Resistance may contain, may be upstream. To the Center tap 23 is one in physical contact with the wall 1 bringable contact antenna 27 connected, the one Protective device 28, here in the form of a protective diode upstream can be.

Die Kontaktantenne 27 kann an der Wand 1 angebracht oder , wie im dargestellten Beispiel, in eine zugeordnete Wandausnehmung eingesetzt sein. In jedem Falle findet zweckmäßig eine sogenannte Kontaktpaste Verwendung, um einen satten körperlichen Kontakt herzustellen. Die Kontaktantenne 27 kann aus einem Stab bestehen, der zweckmäßig in einer Isolierhülse 32 aufgenommen, vorzugsweise in eine diese bildende Isolierung eingegossen ist.The contact antenna 27 may be attached to the wall 1 or as in the example shown, in an associated wall recess be used. In any case, a so-called Contact paste use to provide a rich physical contact manufacture. The contact antenna 27 may consist of a rod exist, which suitably received in an insulating sleeve 32, is preferably poured into an insulating this forming.

Bei dem der Figur 2 zugrundeliegenden Beispiel besteht die in eine zugeordnete Bohrung 29 der Wand 1 eingesetzte, stabförmige Kontaktantenne 27 aus einem stabförmigen Tragkern 30, der als Ferritstab ausgebildet sein kann, und einer auf den Tragkern 30 ausgebrachten Wicklung 31 einer für den Frequenzbereich von 141 kHz geeigneten Hochfrequenzlize. Diese kann mit einer Isolierung versehen sein, so daß sich eine weitergehende Isolierung erübrigt. Vielfach kann es aber zweckmäßig sein, wie gezeichnet, den Tragkern 30 mit der Wicklung 31 in eine umfassende Isolierung 32 einzusetzen oder einzugießen. Das eine Ende der die Wicklung 31 bildenden Hochfrequenzlize ist mit der Mittelanzapfung 23 der Spulenanordnung 22 verbunden. Das andere Ende der Lize ist mit dem Gerätepotential der Sendeeinrichtung 5 verbunden.In the example underlying the figure 2 consists in a associated bore 29 of the wall 1 used, rod-shaped Contact antenna 27 from a rod-shaped support core 30, as Ferrite rod may be formed, and one on the support core 30th applied winding 31 one for the frequency range of 141 kHz suitable Hochfrequenzlize. This can be insulated be provided so that a more extensive insulation is unnecessary. Often it may be appropriate, as drawn, the Support core 30 with the winding 31 in a comprehensive insulation 32nd to insert or pour in. The one end of the winding 31 forming Hochfrequenzlize is with the center tap 23 of the Coil assembly 22 connected. The other end of the Lize is with connected to the device potential of the transmitting device 5.

Im dargestellten Beispiel ist lediglich eine in die Wand 1 eingebrachte Kontaktantenne 27 vorgesehen. Es wäre ohne weiteres denkbar, mehrere, zweckmäßig parallel geschaltete Kontaktantennen 27 vorzusehen, die gleichmäßig über das zu entfeuchtende Bauwerk verteilt sein können. Dasselbe gilt natürlich auch für die Freiluftantennen.In the example shown, only one in the wall 1 introduced contact antenna 27 is provided. It would be without further conceivable, several, suitably connected in parallel Provide contact antennas 27, evenly over the zu dehumidifying structure can be distributed. The same applies Of course, for the outdoor antennas.
