DUCT COMBINATION SENSOR FOR HUMIDITY AND TEMPERATURE – KFFT/M – M12 Connection
KFFT/M-X/S
Anwendung
Device for measuring humidity and 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.
