● 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
● Application Field ─ monitor differential pressure of Cleanroom / hospital / air duct / filter environment and monitor air flow
