Pressure sensor high performance compact pressure transmitter by using ASIC signal conditioning chip and dryceramic capacitive pressure sensor. It has features of anti corrosion, anti-wear, shock resistance and vibration resistance. lts anti-overload capacity is 5~10 times of therange, completely solved poor overload in small range of other sensors. ln addition to general ranges of normal sensors, itsmost outstanding characteristic is the positive and negativegauge pressure function. As high output and wide range of itscore ceramic capacitive sensor, WNK8OMA is especially suitablefor harsh industrial environment pressure measurement.
