Data-Sheet
INDOOR COMBINATION SENSOR FOR RELATIVE HUMIDITY AND TEMPERATURE – RFFT/R-X/S
RFFT/R-X/S
Anwendung
Apparatus for measuring the relative humidity and/or temperature in living and office spaces, reception halls, foyers etc. 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.
