Metal Capacitive Pressure Sensor
UPX3351 metal capacitive pressure sensor uses two plate capacitors as sensitive elements. The sensor is a complete welded-sealing module, the processing pressure is transmitted to the diaphragm of sensitive element through isolated diaphragm and filled silicon oil, to cause the capacity boards displacement to change, thus makes the changes of capacitive signal.
This metal capacitive pressure sensor can have capacitance signal directly, simultaneously the amplified circuit can also be installed in sensor's neck, to make it have 4~20mA standard output signal.
