Model : eYc PHM33

‧ 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
