Digital  RS485 pressure transmitter

Introduction of RS485 pressure transmitter :

485 communication pressure transmitter adopt external power supply, with field display and output digital communication interface functions, 4-20 ma current signal output.

Application of RS485 pressure transmitter :

The pressure transmitter apply to support the system or equipment through the RS485 communication pressure acquisition 

Pressure monitoring and remote transmission of oil wells and gas wells.

Apply for pressure parameter cquisition of large area network.
