Vakuum Switches

What does “piezoresistive” mean?

By changing the pressure, a thin membrane deforms on which a resistor bridge is mounted on the rear. These piezoresisitive resistors change with strain and pressure. The resulting deformation is used to measure the absolute pressure.

How to set the switching point?

After the disassembly of the case which prevents accidental adjustment, the setting of the switching point is done with a potentiometer. The value of the switching point is displayed as a 0-1V analog signal for control purposes.

Can you display the measurement values?

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