4-20mA Pressure Transmitter

Pressure Transmitter

The 4-20mA Pressure Transmitter is easily integrated into an existing SCADA system, digital display and 3rd party data logger. It will provide a continuous, accurate water level reading for a wide variety of applications.

A two-wire 4-20mA Pressure Transmitter current configuration is used with our pressure transmitter which is the most widely used signal transmission for transducers in industrial environments.

“It is the Distributor’s and/or User’s responsibility to ensure chemical, temperature, radiative, and shock compatibility with their site(s) before, during and after deployments. Not doing so will void any and all warranties”
