Piezo-resistive silicon sensor
The PIEZOVAC PV 101 operates with an internal piezo-resistive silicon sensor able to measure from 1200 to 0.1 mbar. Under the influence of pressure a thin diaphragm is bent, and on it‘s back a resistor-bridge is applied. The bending forces the measurement-bridge to come out of tune, which is a measure for the applied pressure.
The PIEZOVAC PV 101 has been specially developed for food sector deployments. Thanks to its detachable flange connection the size of the sensor was significantly reduced. The exclusive use of its piezo sensor significantly increases the battery’s service life so that the device is continuously ready for operation. With a measuring rate of minimum 50 ms, you are informed in short process times on the current pressure.
