Schneider Electric (Barber Colman) 2232-150 Duct Mounted Humidity Transmitter 0-100% RH

The Schneider Electric (Barber-Colman) 2232-150 is a duct-mounted humidity transmitter intended for HVAC systems, specifically air handlers and furnaces. This important part monitors and transmits the percentage of moisture in the air passing through the ductwork, which helps to regulate the amount of humidity inside. The sensor of the 2232-150 detects changes in humidity using a variety of technologies, including resistive and capacitive approaches. After that, the sensor transforms these variations into an electrical signal (usually a voltage or current) according to the relative humidity level. The HVAC control board then receives this signal and uses it to regulate other system parts, such dehumidifiers and humidifiers, to maintain pre-set humidity levels.
