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.
An LCD display option is also available which 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-USB Configuration Kit, if required.
Stem length: 266mm long.
A datalogging feature is provided via either USB or NFC (compatible Android device) connectivity.
