1, Principle structure:
Adopt high performance silicon piezoresistive pressure oil filling core, the internal special integrated circuit will sensor millivolt signal into the standard distance transmission current signal, can be directly connected with the computer interface card, control instrument, intelligent instrument or PLC convenient connection.
2, High temperature and explosion-proof pressure sensor product features:
(1) Adopts diffused silicon piezoresistive sensor, and the shell is solid aluminum alloy junction box with good sealing.
(2) can be used for gas, liquid, steam pressure measurement and provide low pressure, medium pressure, high pressure rich range of pressure
(3) excellent corrosion resistance, can be measured to a variety of media
(4) High protection level
(5) over voltage and over current protection circuit
