PRESENTATION
RHT-WM
and
RHT-DM
transmitters feature highly accurate and stable sensors for measuring relative humidity and temperature. The measured
values are converted into 4 to 20 mA output signals linearly related to their readings.
The microprocessor-based circuit can be configured with the
TxConfig
communication interface and Windows software. It is possible to configure
the measurement and humidity transmission between
Relative Humidity
and
Dew Point
.

MECHANICAL INSTALLATION
The
RHT-DM
(Duct Mount) model must be attached with a flange. The flange is attached to the duct wall. After this, the transmitter probe must be
inserted into the flange center hole and then fixed.
Figure 1
shows the dimensions and drilling of the polyamide 6.6 flange:

The
RHT-WM
(Wall Mount) model must be attached to the wall. By removing the transmitter cover, you can access the two fixing holes and the
connector, as shown in
Figure 3
.
To ensure the specified accuracy and protection degree, you must mount the transmitter with the sensor
capsule facing down
