Description

Die Erfindung betrifft einen autonomen Temperaturtransmitter zum Einsatz verfahrenstechnischen Anlagen.The invention relates to an autonomous temperature transmitter for use in process plants.

Derartige autonome Temperaturtransmitter sind dadurch gekennzeichnet, dass Daten und Informationen drahtlos versendet werden können und die nötige Energie zur Versorgung des Feldgerätes ohne Drahtverbindung zu einer Einspeisestelle zur Verfügung steht. Während für die drahtlose Kommunikation die für sich bekannte Funknetz-Technologie zur Verfügung steht, ist die autonome Energieversorgung unter industriellen Anforderungen problematisch. Das trifft auch auf in der Industrie in großem Umfang eingesetzte Temperaturtransmitter zu. Stand der Technik ist der Einsatz von Batterien, um eine autonome Energieversorgung zu ermöglichen. Dies erfordert jedoch eine regelmäßige Überwachung. Der Austausch verbrauchter Batterien ist aufwendig und oft auch kostenintensiv und wird daher von den Betreibern nicht akzeptiert.Such autonomous temperature transmitters are characterized in that data and information can be sent wirelessly and the necessary energy is available for supplying the field device without a wire connection to a feed point. While the wireless network technology known per se is available for wireless communication, the autonomous power supply under industrial requirements is problematic. This is also true of industry-widely used temperature transmitters. The state of the art is the use of batteries to enable an autonomous power supply. However, this requires regular monitoring. The replacement of used batteries is expensive and often expensive and is therefore not accepted by the operators.

Darüber hinaus sind aus den DE 10 2007 051 672 A1 und DE 10 2008 038 980 A1 Einrichtungen zur Energieversorgung von Mess- und Sendeeinrichtungen bekannt, die den Energiegehalt des Mediums, dessen Temperatur gemessen werden soll, ausnutzen. Dabei wird die benötigte elektrische Energie für die Elektronik durch einen thermoelektrischen Generator (TEG) aus der Temperaturdifferenz zwischen dem Medium und der Umgebung erzeugt. Dabei kommen neben konventionellen TEGs auch Dünnschicht-TEGs, beispielsweise in Folienform, oder Mikro-TEGs zum Einsatz.In addition, from the DE 10 2007 051 672 A1 and DE 10 2008 038 980 A1 Devices for power supply of measuring and transmitting devices known that exploit the energy content of the medium whose temperature is to be measured. The required electrical energy for the electronics is generated by a thermoelectric generator (TEG) from the temperature difference between the medium and the environment. In addition to conventional TEGs, thin-film TEGs, for example in foil form, or micro-TEGs are used.

Der Einsatz der bekannten Lösungen stößt jedoch in einem industriellen Umfang schnell an ihre Grenzen. Der zur Verfügung stehende Bauraum ist begrenzt, die Funktionssicherheit muss auch in explosionsgefährdeter Umgebung oder in Gegenwart aggressiver Gase gewährleistet sein. Die bislang bekannten Konstruktionen bieten hierfür noch keine Möglichkeit. Vor allem modulare Anklemm-Lösungen, wie sie aus der WO 2008/042073 A2 bekannt sind, sind unzureichend im eigentlichen Messgerät oder Feldinstrument integriert.However, the use of the known solutions quickly reaches its limits on an industrial scale. The available space is limited, the functional safety must be guaranteed even in explosive environments or in the presence of aggressive gases. The previously known constructions offer no possibility for this. Especially modular clamping solutions, as they are made from WO 2008/042073 A2 are known, are insufficiently integrated in the actual instrument or field instrument.

Schließlich ist aus der DE 10 2007 056 150 A1 ein Sensorsystem mit einem thermoelektrischen Wandler zu seiner Speisung bekannt, der bei Einwirken eines Temperaturgefälles eine elektrische Spannung erzeugt, mit einem Trägerelement, das einen Wärmeleitkern aufweist, der den Sensor und den thermoelektrische Wandler thermisch an das die Messgröße darstellende Prozeßmedium koppelt. Die Bauform dieses Prüfmittels genügt nachteiligerweise nicht den Sicherheitsanforderungen im industriellen Bereich. Bei hohen Temperaturen des Prozeßmediums besteht die Gefahr der Zerstörung des thermoelektrischen Wandlers durch Überschreitung dessen zulässiger Betriebsparameter.Finally, out of the DE 10 2007 056 150 A1 a sensor system with a thermoelectric converter for its supply known, which generates an electrical voltage when exposed to a temperature gradient, with a support member having a Wärmeleitkern which thermally couples the sensor and the thermoelectric transducer to the process variable representing the process medium. The design of this tester disadvantageously does not meet the safety requirements in the industrial sector. At high temperatures of the process medium there is a risk of destruction of the thermoelectric converter by exceeding its permissible operating parameters.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Speiseeinrichtung für einen autonomen Temperaturtransmitter mit einem thermoelektrischen Wandler anzugeben, der bei hoher Energieausbeute vor hohen Temperaturen des Prozeßmediums geschützt ist.The invention is therefore based on the object to provide a feed device for an autonomous temperature transmitter with a thermoelectric converter, which is protected at high energy yield from high temperatures of the process medium.

Die Erfindung geht aus von einem Temperaturtransmitter aus, der teilweise in ein Prozeßgefäß hineinragt, in dem ein Prozeßmedium eingeschlossen ist, dessen Temperatur gemessen werden soll, dessen aus dem Prozeßgefäß herausragender Teil eine Elektronikkomponente aufnimmt und der zur Speisung einem thermoelektrischen Wandler aufweist.The invention is based on a temperature transmitter, which projects partially into a process vessel in which a process medium is enclosed, the temperature of which is to be measured, whose projecting from the process vessel part accommodates an electronic component and which has a thermoelectric converter for feeding.

Erfindungsgemäß ist der thermoelektrische Wandler von der Quelle der unzulässigen Betriebstemperaturen durch ein Abstandselement geringer Wärmeleitfähigkeit beabstandet. Dadurch wird erreicht, dass die den zulässigen Betriebsbereich verlassenden Temperaturen auf dem Weg zum thermoelektrischen Wandler reduziert werden.According to the invention, the thermoelectric converter is spaced from the source of impermissible operating temperatures by a spacer of low thermal conductivity. This ensures that the temperatures leaving the permissible operating range are reduced on the way to the thermoelectric converter.

Durch verschiedene Längen und/oder Wärmeübertragungskoeffizienten des Abstandselements sind unterschiedliche Temperaturbereiche außerhalb der zulässigen Betriebstemperaturen zugänglich. Vorteilhafterweise bleibt die Bauart des Temperaturtransmitters über einen weiten Temperaturbereich des Prozeßmediums unverändert. Dies gilt gleichermaßen für Unterschreitungen wie für Überschreitungen des Bereichs der zulässigen Betriebstemperaturen.By different lengths and / or heat transfer coefficients of the spacer different temperature ranges outside the allowable operating temperatures are accessible. Advantageously, the design of the temperature transmitter remains unchanged over a wide temperature range of the process medium. This applies equally to underruns and overshoots of the range of permissible operating temperatures.

Durch den thermische Übergangswiderstand zwischen dem Wärmeträger und dem Wandler wird der Wandler vor unzulässigen Temperaturen geschützt.Due to the thermal contact resistance between the heat transfer medium and the converter, the converter is protected from impermissible temperatures.

Die Erfindung wird nachstehend anhand von Ausführungsbeispielen näher erläutert. Die dazu erforderlichen Zeichnungen zeigen:The invention will be explained in more detail below with reference to embodiments. The necessary drawings show:

1 eine Prinzipdarstellung eines Temperaturtransmitters mit einem thermoelektrischen Wandler 1 a schematic diagram of a temperature transmitter with a thermoelectric converter

2 eine Prinzipdarstellung eines alternativen Temperaturtransmitters mit einem thermoelektrischen Wandler 2 a schematic diagram of an alternative temperature transmitter with a thermoelectric converter

In der 1 ist ein Temperaturtransmitter mit einem thermoelektrischen Wandler 32 teilweise geschnitten dargestellt. Der Temperaturtransmitter umfasst ein nach außen offenes Schutzrohr 13, das in ein Prozeßgefäß 20 hineinragt, in dem ein Prozeßmedium 21 eingeschlossen ist. Der Temperaturtransmitter umfasst ferner einen Kopf 10, in dem eine Elektronikkomponente 11 untergebracht ist. Die Elektronikkomponente 11 ist mit einem Sensor 14 verbunden, der im Inneren des Schutzrohres 13 an dessen geschlossenen Ende angeordnet ist.In the 1 is a temperature transmitter with a thermoelectric converter 32 shown partially cut. The temperature transmitter includes a protective tube open to the outside 13 that in a process vessel 20 protrudes, in which a process medium 21 is included. The temperature transmitter further comprises a head 10 in which an electronic component 11 is housed. The electronic component 11 is with a sensor 14 connected inside the protective tube 13 is arranged at the closed end.

Die Elektronikkomponente 11 ist von dem thermoelektrischen Wandler 32 gespeist, der über ein thermisches Leitelement 33 kopfseitig mit einem Kühlkörper 34 in thermischer Wirkverbindung stehend angeordnet ist. Die thermischen Leitelemente 33 sind vorzugsweise als für sich bekannte Wärmeleitrohre oder sogenannte Heatpipes ausgebildet und in einem Halsrohr 12 untergebracht. Dabei sind die kopfseitige Temperatur des Wandlers 32 etwa gleich der Umgebungstemperatur des Kühlkörpers 34. Der Kühlkörper 34 ist gerippt ausgebildet, von der Umgebungsluft umspült und somit an deren physikalische Größe Temperatur ankoppelt.The electronic component 11 is from the thermoelectric converter 32 fed by a thermal conduction element 33 head side with a heat sink 34 is arranged in thermal operative connection standing. The thermal vanes 33 are preferably designed as known heat pipes or so-called heat pipes and in a neck tube 12 accommodated. Here are the head-side temperature of the transducer 32 approximately equal to the ambient temperature of the heat sink 34 , The heat sink 34 is ribbed formed, lapped by the ambient air and thus coupled to the physical size of temperature.

Die gefäßseitige Temperatur des Schutzrohres 13 ist etwa gleich der Temperatur des Prozeßmediums 21. Zum Schutz des Wandlers 32 vor unzulässigen Temperaturen ist zwischen dem Schutzrohr 13 und dem Wandler 32 ein Abstandselement 36 angeordnet. Dadurch wird vermieden, dass der Wandler 32 mit unzulässigen Temperaturen beaufschlagt wird.The vessel-side temperature of the protective tube 13 is about equal to the temperature of the process medium 21 , To protect the converter 32 against inadmissible temperatures is between the protective tube 13 and the converter 32 a spacer element 36 arranged. This will avoid the transducer 32 is subjected to impermissible temperatures.

In der 2 ist unter Verwendung gleicher Bezugszeichen für gleiche Mittel ein Temperaturtransmitter in einer alternativen Ausführungsform der Erfindung dargestellt. Der Temperaturtransmitter ist gefäßseitig zur Flanschmontage ausgebildet. Dabei ist das in das Prozeßgefäß 20 hineinragende Schutzrohr 13 mit einem Flansch 37 ausgetattet, der mit dem Prozeßgefäß 20 verbunden ist und dieses verschließt. Demnach ragt ein Teil des Schutzrohres 13 aus dem Prozeßgefäß 20 heraus.In the 2 is a temperature transmitter in an alternative embodiment of the invention using the same reference numerals for the same means shown. The temperature transmitter is designed on the vessel side for flange mounting. It is in the process vessel 20 protruding protective tube 13 with a flange 37 dumped with the process vessel 20 is connected and this closes. Accordingly, a part of the protective tube protrudes 13 from the process vessel 20 out.

Der Wandler 32 zur Speisung der nicht dargestellten Elektronikkomponente im Kopf 10 ist direkt mit dem Schutzrohr 13 verbunden. Dabei ist der Abstand zwischen dem Wandler 32 und dem Schutzrohr 13 ein Maß für die nötige Temperaturdifferenz zwischen der zulässigen gefäßseitigen Wandlertemperatur und der Prozeßtemperatur.The converter 32 for feeding the electronic component, not shown in the head 10 is directly with the protective tube 13 connected. Here is the distance between the transducer 32 and the protective tube 13 a measure of the required temperature difference between the permissible vessel-side converter temperature and the process temperature.

Kopfseitig ist der Temperaturtransmitter durch einen Kühlkörper 34 gebildet, der mit dem Wandler 32 in thermischer Wirkverbindung steht. Dabei kann ein Halsrohr 12 vorgesehen sein, in dem thermischen Leitelemente 33 gemäß 1 untergebracht sind. Bei ausreichendem Abstand zwischen dem Wandler 32 und dem Flansch 37 kann der Kühlkörper 34 auch direkt mit dem Wandler 32 verbunden sein.At the top is the temperature transmitter through a heat sink 34 formed with the converter 32 is in thermal active compound. It can be a neck tube 12 be provided in the thermal vanes 33 according to 1 are housed. With sufficient distance between the transducer 32 and the flange 37 can the heat sink 34 also directly with the converter 32 be connected.
