A cost effective "smart" duct-mounted humidity/temperature transmitter with a single, two wire 4~20mA output or dual, two wire 4~20mA output. The design uses a digital sensor which plugs into the sensor stem.

The product will measure humidity, temperature, dew point and delta T (the difference between dewpoint and ambient temperature) values.

A 4-digit (9mm) LED display option is also available which can be rotated to suit the application. This provides a visual indication of the process parameters. The display may be set to indicate either humidity, temperature, dew point or toggle between all three parameters.

Supplied pre-ranged, but can easily be configured using the TX-KIT (USB Transmitter Configuration Kit), if required.

Stem length: 250mm long.
