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