A cost effective smart humidity transmitter with a single two wire (4 to 20) mA output or dual two wire (4 to 20) mA output. The design uses a digital sensor which plugs into the sensor stem. A 4 digit display option is also available which can be rotated to suit the application. The product will measure humidity, temperature, dew point and delta T (the difference between dewpoint and ambient temperature) values. Stem length 170mm long.
