Air humidity High-precision sensor for temperature, humidity, atmospheric pressure FHAD 36 RAx Wide operating temperature range Automatic atmospheric pressure compensation Digital sensor with ALMEMO® D6 plug General features, see chapter ALMEMO® Measuring instruments Common technical features FHAD 36 RAx • Digital capacitive humidity sensor with integrated signal • processor, designed to meet the highest accuracy requirements in humidity measurement • • Unique correction and adjustment process All sensor characteristics and adjustment data are saved in the humidity sensor itself. • • A digital atmospheric pressure sensor integrated in the • ALMEMO® D6 plug itself provides automatic pressure compensation for all pressure-dependent humidity variables. • Humidity calculation on the basis of formulae as per Dr. Sonntag and the enhancement factor as per W. Bogel (correction factor fw(t,p) for real mixed gas systems) This substantially widens the measuring range and improves the accuracy of humidity variable calculations. • Humidity variable, Absolute humidity in g/m3 All relevant ambient parameters are measured with just one sensor. The humidity variables are calculated from the three primary measuring channels (real measurable variables) temperature, relative humidity, atmospheric pressure Freely selectable measurable variables Four measuring channels are programmed (at our factory) temperature (°C, T, t), relative humidity (%H, RH, Uw), dewpoint (°C, DT, td), atmospheric pressure (mbar, AP, p). Other humidity variables can also be selected: mixture (g/kg, MH, r), absolute humidity (g/m3, AH, dv), vapor pressure (mbar, VP, e), enthalpy (kJ/kg, En, h). This device can be configured directly on a PC using USB adapter cable ZA 1919 AKUV (see chapter „Networking“). ! The recommended application range for capacitive sensors is up to dew point temperatures in the range of 80 °C td. Measurements at high humidity and high temperatures can lead to a larger sensor drift with capacitive sensors. Permanent changes in sensor characteristics can be caused by chemical / physical processes. Contamination in the measuring medium and falling below the dew point temperature (in extreme climates), can further intensify this effect.
