Metal Capacitive Pressure Sensor
UPX3351 metallic 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.
UPX3351 can output capacitance signal directly, simultaneously the amplified circuit can also be installed in sensor's neck, to make it have 4~20mA standard output signal.
UPX3351 is widely used in drugs manufacturing, food industry as well as environmental protection etc.
