All-metal pressure sensitive diaphragm for impact resistance
It is suitable for construction machinery hydraulic system with severe cavitation, liquid hammer phenomenon, high pressure peak, large power supply fluctuation, vibration interference and other harsh environment.
The pressure sensor sputters a Wheatstone bridge on the metal diaphragm, and the pressure of the measured medium (gas or liquid) changes the resistance value of the bridge wall (piezoresistic effect), resulting in a differential voltage signal, which is converted into a standard analog signal or a digital signal by a special amplifier.
