P.A.20325't*26.3.63P.A. 20325't * March 26, 63 Besehreibung des Grenzmarken-SuchgerätesDescription of the boundary marker search device In der Yermessungstechnik werden eingemessene Punkte ihrer geographischen Lage nach mit G-renzsteinen markiert. In neuerer Zeit verwendet man zunehmend anstelle von Grenzsteinen sogenannte Grenzmarken. Diese Grenzmarken "bestehen aus einer Kunststoffplatte,welche mit einem angesetzten Eisenrohr so im Boden verankert wird, dass die Kunststoffplatte sichtbar bleibt.In the measurement technique, measured points are their geographical Location marked with border stones. Recently, so-called boundary marks have been used increasingly instead of boundary stones. These border marks "consist of a plastic plate, which is anchored in the ground with an attached iron pipe so that the plastic plate remains visible. Gelegentlich werden solche Marken etwa bei Bauarbeiten verschüttet und müssen dann wieder aufgesucht werden. Zu diesem Zwecke wurde ein sogenanntes Grenzmarken-Suchgerät entwickelt. Dieses Gerät arbeitet auf der Basis eines magnetischen Wechselfeldes, nach der Gegeninduktivitätsmethode. Eine Senderspule strahlt ein magnetisches Feld aus. Eine Empfängerspule ist innerhalb dieses Feldes so angeordnet, dass in ihr bei ungestörtem Feldlinienverlauf keine Spannung induziert wird. Tritt eine Grenzmarke in den Wirkungsbereich des Magnetfeldes, wird der Verlauf der Feldlinien verzerrt. Demzufolge wird eine Spannung in der Empfängerspule induziert und nach entsprechender Verstärkung optisch und akustisch signalisiert. Die Stärke dieses Signal: wächst mit der Annäherung des Suchgerätes an die Grenzmarke und erreicht unmittelbar über ihr ein Maximum.Occasionally, such marks are spilled during construction work, for example and then have to be visited again. For this purpose, a so-called boundary marker locator was developed. This device works on the basis of an alternating magnetic field, according to the mutual inductance method. A transmitter coil emits a magnetic field. A receiver coil is arranged within this field so that no voltage is induced in it if the course of the field lines is undisturbed. If a boundary marker enters the effective area of the magnetic field, the course of the field lines is distorted. As a result, tension becomes induced in the receiver coil and signaled optically and acoustically after appropriate amplification. The strength of this signal: grows as the locator approaches the limit mark and reaches a maximum immediately above it. Konstruktiv besteht das Gerät aus dem Suchkopf (Teil 1) mit Senderund Empfängerspule, dem gerade oder schräg angesetzten Stiel (Teil 2), dem Geräteteil (Teil 3) mit den Bedienungselementen, in dem sich der transistorisierte elektronische Teil befindet, dem Ableseinstrument (Teil 4) sowie dem Tragegriff (Teil 5) mit eingebautem Einschalter.In terms of design, the device consists of the seeker head (part 1) with transmitter and Receiver coil, the straight or angled handle (part 2), the device part (part 3) with the controls, in which the transistorized electronic part is located, the reading instrument (Part 4) and the handle (Part 5) with built-in switch. Im Geräteteil ist zur Stromversorgung des Gerätes ein Klein-Akkumulator fest eingebaut, der mit einem ebenfalls eingebautem Ladegerät über eine Geräteschnur vem Lichtnetz aufgeladen werden kann.In the device part there is a small accumulator for the power supply of the device Permanently installed, which can be charged with a built-in charger via a device cord from the lighting network.
