PRESSURE SENSOR

PURPOSE: To improve the safety of a pressure sensor provided with a diaphragm which cooperates with at least one resistor the resistance value of which varies depending upon a pressure against cracking by sufficiently avoiding the deflection of the diaphragm. CONSTITUTION: Piezoelectric resistors 28...

Zusammenfassung:	PURPOSE: To improve the safety of a pressure sensor provided with a diaphragm which cooperates with at least one resistor the resistance value of which varies depending upon a pressure against cracking by sufficiently avoiding the deflection of the diaphragm. CONSTITUTION: Piezoelectric resistors 28 and 29 are arranged on a diaphragm 24 and the resistors 28 and 29 are connected to each other so that they can form a measuring bridge together with resistors 26 and 27 which are not subjected to loads. In addition, the diaphragm 24 cooperates with a counter member 21 so that the resistors 28 and 29 which work as sensor elements when a pressure is applied can receive the pressure.
