Detailed Product Description

The Transmitter is a small though robust device which converts the raw sensor signal of an electrochemical sensor cell into a standard 4~20 mA output. Additionally, the output signal is converted by an on-board resistor into a 40~200 mV voltage output.

The Transmitter board is available for all existing electrochemical gas sensors.

The Transmitter Board has on-board temperature compensation and allows the use of an optional external temperature sensor for temperature compensation.
In general, it is shipped fully calibrated including the sensor cell. There are two possibilities for recalibration.
when appropriate:
by use of a small button for zero and/or span calibration and
by use of a potentiometer for span calibration.
