HIGH TEMPERATURE/HUMIDITY SENSOR – ARFT/R-X/HT
ARFT/R-X/HT
Anwendung
Device for measuring the relative humidity/temperature in outdoor areas or indoor areas subject to high requirements. The measuring transducer measures 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. Additionally, a passive temperature sensor can be connected. Various measuring ranges are available depending on the model. The sensor features long-term stability and no recalibration is required.
