‧ The principle of differential pressure transmitter is measuring trace of differential pressure, the air through pressure in and pressure out, PCB will transduce it to differential pressure signal.
‧ Silicon chips on Thermo Differential Pressure Module of MEMS integration technology
‧ Off set function by bottom / UI software
‧ Low-pressure monitoring, high pressure bearable
‧ Option RS-485 communication interface, Modbus RTU protocol
‧ DIP switch output and range
‧ Physical switch:mbar / Pa / hPa / kPa / mmH2O / mmWS / inH2O / mmHg
‧ Square root function
