Metal Capacitive Pressure Sensor
Brand: Xi'an UTOP Measurement Instrument Co, LtdUPX3351 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 4~20 mA standard output signal.
Features- All-welded structure, suitable for measuring many kinds of media
- Isolated diaphragm material: 316L, Hastelloy-C, Monel, Tantalum
- Measuring ranges: -100…0 kPa~1.6 kPa…40 MPa
- System pressure up to 312 bar for differential applications
- Pressure type: gauge pressure, absolute pressure, micro differential pressure and differential pressure
- High quality metal capacitive pressure sensor
