dynamic MELA® humidity sensing element
calibrated dModul for
humidity and temperature measurement
with integrated measuring chamber
easy to install
operating temperatures up to 60°C
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 integrated measuring chamber of the room version is separated from the electronics. Thus, a good air circulation around the sensing elements is provided.
The housing of the room version has a simple and robust closing mechanism. After mounting the base part, the top which contains the transmitter electronics, can be easily clipped into place and pressed shut without any tool.
