Pressure Transmitter difference type

  • Pressure Transmitter difference type
  • Pressure Transmitter difference type 3051/3351DP measure the pressure of liquid, gas and steam, adopt the piezoresistive effect of silicon, the pressure single can transfer to electrical single. When pressure working on diaphragm, the single will be transfer to sensor part by silicon, after temperature compensation and linearity correction converted it into 4-20Madc standard current signal output.
  • That have level difference type, high hydrostatic pressure difference type, micro difference type, can communicate with operator by HART to set and monitor.
