SENSOR FOR RELATIVE HUMIDITY/TEMPERATURE Duct combination sensor
KFFT/R-X/S
Device for measuring the relative humidity/temperature in ducts or indoor areas subject to high requirements. The measuring transducer records the temperature and humidity via an internal sensor and coverts the value into a standardized analogue output signal in the range between 0-10V/4-20 mA.
