pressure transmitter measuring principle 
 

Description of pressure transmitter measuring principle : 

  pressure transmitter linearity uses diffused silicon imported chips, circuit signal isolation amplifier, cutoff frequency interference design (anti-interference ability, lightning) overvoltage protection, current limiting protection, impact and corrosion. Hydraulic pressure sensor housing full seal welded 316 stainless steel, compact, compact, good moisture resistance and excellent media compatibility.
