Description
Combined duct Sensor for relative humidity and temperature – KFFT/R-xxx-I/SD
For measuring relative humidity and temperature in ducts or in rooms with increased protection requirements. The transmitter records the temperature and rel. humidity via an internal Sensor and converts it into a standardized analog output signal 0-10V or 4-20mA. Overview of humidity sensors
