Capacitive pressure sensor or differential pressure sensor; it is all welded construction with stainless steel material. This kind of pressure sensor is to sense the pressure or differential pressure via the oil filling in the sensor .It can sensor minimum 0-0.16~1.6Kpa differential pressure or 0-16~40Mpa gauge pressure with high accuracy.The sealed chamber integrated temperature diode, this diode supplied real time temperature parameters for the capacitance pressure transducer, and it provides temperature compensation for the capacitance pressure transmitters.
