Abstract

The continuously adjustable level electrode can measure the level of conducting liquids point by point in containers, tanks, etc. When the sensor touches the liquid an electrical connection is made via the conducting liquid to a second contact or to the container wall. The electrical connection is processed further via a connected a.c. amplifier. The sensor requires only one rod or tube (1) on which are arranged several sensors which are continuously adjustable in height. All electrical connections are fed through a common connector top (2). The arrangement makes economical use of expensive materials. The adjustment of the contacts can be performed by using a single spindle (6) in the probe connector head (2).

Description

Stufenlos verstellbare Fülis-tandselektrodeInfinitely adjustable level electrode

Die stufenlos verstellbare Füllstandselektrode hat den Zweck, punktweise die Füllhöhe leitender Flüssigkeiten aller Art in Behältern, Tanks, und sonstigen Behältern abzutasten. Bei Berührung des Fühlers (Stab aus Metall und auch Halbleitern, z.B.The steplessly adjustable level electrode has the purpose of point-by-point the filling level of conductive liquids of all kinds in containers, tanks and others To scan containers. When touching the sensor (rod made of metal and semiconductors, e.g.

Kohlestifte) mit dem Medium blidet das leitfähige Medium mit einem zweiten Fühlerkontakt oder der Wandung der Behälter eine elektrische Verbindung. Diese elektrische Verbindung wird iiber einen angeschlossenen Wechselspannungsverstärker weiterverarbeitet.Carbon pencils) with the medium blides the conductive medium with a second sensor contact or the wall of the container an electrical connection. This electrical connection is made via a connected AC voltage amplifier further processed.

Die bisher auf dem Markt vorhandenen Abtastfühler (häufig genannt Abtastelektroden) weisen folgende Mängel auf: 1. Unveränderlicher Schaltpunkt 2. Abtastelektroden, die verstellbar sind, haben keinen gemeinsamen Anschlußopf g, Hängende Abtastelektroden sind bei bewegten Medien nicht fixiert 4. Die Anzahl der Schaltpunkte bestimmt die Anzahl der Stäbe Die Erfindung zeichnet sich dadurch aus, daß die stufenlos verstellbare Füllstandselektrode (Abtastfühler) nur 1 Stab bzw. Rohr besitzt, an dem 1 oder mehrer Abtastfühler stufenlos in der Höhe verstellbar sind. Alle Schaltpunkt (elektrische Verbindungen) werden in einen gemeinsamen Anschlußkopf geführt. Bei bewegten Medien bleiben durch die Festlegung der Abtastelektroden an 1 Stab die Füllstandshöhen genau fixiert.The scanning sensors available on the market up to now (often called Scanning electrodes) have the following deficiencies: 1. Fixed switching point 2. Scanning electrodes, which are adjustable, do not have a common connection pot g, Hanging scanning electrodes are not fixed in the case of moving media 4. The number of Switching points determine the number of rods The invention is characterized by that the continuously adjustable level electrode (scanning sensor) only requires 1 rod or Tube has 1 or more scanning sensors infinitely adjustable in height are. All switching points (electrical connections) are in a common connection head guided. With moving media remain on due to the definition of the scanning electrodes 1 stick precisely fixes the fill level.

Durch diese Konstruktion ergibt sich mit diesem System außerdem -besonders bei sehr teuren Materialien von Abtastfuhlern, wie z.B.This construction also makes this system special in the case of very expensive sensor materials, such as

Tantal und hochlegierten Edelstahlverbindungen eine preiswertere Ausführung, da erheblich weniger von diesem Material verwendet wird.Tantalum and high-alloy stainless steel connections a cheaper version, since considerably less of this material is used.

Die stufenlos verstellbare Abtastelektrode besteht aus 1 Rohr bzw.The continuously adjustable scanning electrode consists of 1 tube or

Stab (Teil 1), Durchmesser 1o...5o mm. Das Material ist c5 Kunststoff oder 1 Metallstab, der mit Kunststoff überzogen bzw. beschichtet wird. Am oberen Ende des Stabels bzw. Rohres ist ein Anschlußkopf (Teil 2) für die elektrischen Anschlüsse. Die Befestigung der stufenlos verstellbaren Füllstandselektrode erfolgt in der Regel mit einer Verschraubung oder einem Flansch und ist an einer Klemmvorrichtung (Teil 4) direkt befestigt. Diese Klemmvorrichtung umfaßt den Stab und kann an diesem in jeder Höhe stufenlos verschoben werden. Die Klemmvorrichtung Teil 4 kann manuell verstellt werden durch Lösen der Schraube Teil 5 oder durch 1 Spindel Teil 6 vom Anschlußkopf aus.Rod (part 1), diameter 1o ... 5o mm. The material is c5 plastic or 1 metal rod that is covered or coated with plastic. At the top The end of the rod or tube is a connection head (part 2) for the electrical Connections. The continuously adjustable level electrode is attached usually with a screw connection or a flange and is on a clamping device (Part 4) attached directly. This clamping device includes the rod and can on this can be moved steplessly at any height. The clamping device part 4 can be done manually can be adjusted by loosening the screw part 5 or by 1 spindle part 6 of the Connection head off.

Patentanspruchx Die stufenlos verstellbare Füllstandselektrode hat einen oder mehrer Abtastfühler, die stufenlos an 1 Stab oder Rohr eingestellt werden können. Die Einstellung des Kontaktes kann auch durch 1 Spindel im Anschlußkopf der Sonde erfogen. Das Gerät stellt damit einen kompletten Abtastfühler dar, was für alle leitfähigen Medien einsetzbar ist.Patent claimx The continuously adjustable level electrode has one or more scanning sensors, which can be continuously adjusted to 1 rod or tube can. The setting of the contact can also be done by 1 spindle in the connection head the probe succeeded. The device thus represents a complete scanning sensor, what can be used for all conductive media.
