Air Humidity Digital sensor for measuring temperature and humidity FHAD 46-C7 Pressure-sealed variant up to 16 bar, with ALMEMO® D6 plug • Compact sensor made from stainless steel • Screw thread, for pressure pipes • Option - adapter for compressed air pipes • Capacitive digital sensor for humidity and temperature. Additionally EEPROM data storage medium in the multisensor module. • The sensor module is thoroughly adjusted. All sensor characteristic and adjustment data are stored on the data storage medium of the sensor module itself. In the process of readjusting the individual sensors, the adjustment values are directly saved on the data storage medium of the sensor module. • Every sensor module has a unique serial number saved on the humidity sensor. The serial number is either displayed in the sensor menu of the measuring instrument or in the ALMEMO® Connect software. Hence, calibrated sensor modules can clearly be assigned to the calibration certificate. • Replacement sensor modules are inexpensive: The sensor module is pluggable and can simply be exchanged on-site. Full Technical data accuracy without any adjustment, especially with calibrated sensors. The ALMEMO® connecting cable and the ALMEMO® measuring instrument have no influence on the calibration. • The humidity variables are calculated from the two primary measuring channels (real measurable variables): temperature, relative humidity • Three measuring channels are programmed: temperature (°C, T, t), relative humidity (%H, RH, Uw), dewpoint (°C, DT, td). One further humidity variable 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). The configuration of the channels and the input of the system pressure for the automatic pressure compensation of the pressure dependent humidity variables is performed on the ALMEMO® V7 measuring instrument or directly on the PC using the USB adapter cable ZA1919AKUV (see chapter “ALMEMO® Network technology”).
