General information

The industrial versions DK and DW can be used at operating temperatures between -30 ... 80°C. The integrated hx processor uses the values of the relative humidity and the temperature to calculate the dew point, the enthalpy, the mixing ratio, the
absolute humidity or the wet-bulb temperature. Per the customer’s preference, any two of these are emitted at two analogue outputs using standardized signals.

The core part of the D Series is the digital calibrated dModul, which processes the measurement values of relative humidity and temperature individually. The values are compared to the calibration values stored in the dModul and communicated digitally to the transmitter electronics, where they are processed to standardised current and voltage signals.

The housings of the industrial versions provide protection in accordance with IP 65. Only a single screw is required to close it securely
