D Series
Sensors for
Humidity and Temperature Measurement
With calibrated dModul
Type DW
Industrial version for wall mounting
Optional display
•t dynamic MELA® humidity sensing element
•t output of all hx values
• tcalibrated dModul for
t humidity and temperature measurement
•t in situ alignment
•t easy to install
•t operating temperatures up to 80°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 housings of the industrial versions provide protection in accordance with IP 65. Only a single screw is required to close it
securely.
