Heron 4-20mA Pressure Transmitter

The 4-20mA Pressure Transmitter is easily adaptable to telemetry/SCADA systems, digital displays and third party data loggers. The 4-20mA provides highly accurate water level measurements for a wide variety of applications. A two wire 4-20mA current loop is used with our pressure transmitter which is the most widely used signal transmission for transducers in industrial environments.
