Description

The ET18 transmitter series incorporate the best high accuracy and great stability for enthalpy and dew point
temperature sensors. They convert the measured values into linear 4 to 20 mA signals or 0 to 10 VDC output can also be offered under request The microprocessor based circuit enables full configuration of output range when used with the COML protocol for calibration. The sensor can be configured for all psychometric outputs (2 Outputs)
