4-20mA Pressure Transmitter

The Heron 4-20mA Pressure Transmitter is easily integrated into an existing SCADA system, digital display and 3^rd 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 the Heron Pressure Transmitter which is the most widely used signal transmission for transducers in industrial environments.

Vented cable provides real time barometric compensation
Simple two-wire connection
Output signal is compatible with most telemetry, SCADA and PLC systems
High noise immunity on long cable runs
Wide range of supply voltage (7.5VDC-35VDC)
High accurate water level measurements
Reverse polarity protected
