Vakuum Switches

What does “piezoresistive” mean?

By changing the presUnder the effect of pressure, a thin membrane with a resistance measuring bridge on the back is deformed. These piezoresistive resistors change under compressive or tensile stress. The resulting detuning of the measuring bridge is a measure of the absolute pressure acting on the diaphragm.

How is the switching point set?

First, the housing cover must be removed to prevent unintentional adjustment. The switching point is set using a potentiometer, whereby the value of the switching point is output as a 0 - 1 V analog signal for checking purposes.

Can you display the measurement values?

Yes, the measurement values are displayed as a 0-10 V analog signal.
