Abstract

The subject matter of the main application P 3604340.0 is a sensor which has forced ventilation, the air masses in front of the sensor surface being caused to oscillate by an oscillating pump. These oscillating pumps are subject to natural wear. In order to minimise this wear, the invention proposes that the oscillating pump be driven via a pulse-excited magnet, the DC armature being supported in a floating manner between tension springs and compression springs. Very economical DC plunger-type magnet armatures can thus be used, the oscillating movement taking place without any mechanically abutting boundary as a result of the floating, overhung suspension, and thus making it possible to operate with little wear.

Description

In der Hauptanmeldung P 36 04 340.0 ist ein Sensor beschrieben, der eine Zwangsbelüftung aufweist, wobei die Luftmassen vor der Sensoroberfläche in Schwingungen durch eine Schwingpumpe versetzt werden.There is a sensor in the main application P 36 04 340.0 described, which has a forced ventilation, wherein the air masses in front of the sensor surface vibrate be displaced by a vibrating pump.

Schwingpumpen unterliegen einem natürlichen Verschleiß.Vibration pumps are subject to natural wear.

Um diesen Verschleiß zu minimieren, wird erfindungsgemäß vorgeschlagen, daß der Gleichstromanker des Schwingma­ gneten schwimmend eingelagert ist, und zwar zwischen einer Zug- und Druckfeder eingespannt ist. In order to minimize this wear, the invention suggested that the DC armature of the oscillating arm is floating, between one Tension and compression spring is clamped.  

Der Vorteil ist besonders darin zu sehen, daß sehr preiswerte Gleichstrom-Tauchmagnet-Anker Anwendung finden können. Hierbei ist durch die schwimmende, fliegende Einspannung zwischen Zug- und Druckfeder eine Schwingbewegung ohne mechanisch anstoßende Begrenzung vorzufinden, was verschleißarmes Arbeiten besonders ermöglicht.The advantage can be seen particularly in the fact that inexpensive direct current submersible magnet armature application can find. This is due to the floating, flying clamping between tension and compression spring a swinging motion without mechanically abutting Find limitation on what low-wear working particularly enables.
