ELEKTRONISCHER DRUCKSCHALTER, INSBESONDERE ALS MESSGLIED FUER DIE ERFASSUNG VON DRUCKSCHWANKUNGEN IN TEXTILMASCHINEN

摘要

An electronic pressure responsive switch comprises an activating element and at least two sensors. The activating element and the sensors are arranged to be relatively displaceable with respect to one another whereby the sensors each generate signals when the activating element assumes a predetermined position relative to a respective sensor. The switch further has an elastic diaphragm having a first face exposed to pressure to be sensed and a reverse second face carrying either the activating element or the sensors. The diaphragm is deformable by the pressure whereby the relative position between the activating element on the one hand and the sensors on the other hand is varied as a function of the pressure.
