Meteorological transmitter.

Model  Description 
HD 9008 TR  Meteorological transmitter temperature humidity

CHARACTERISTICS
H 6100 capacitive humidity sensor.
Pt1 00 temperature sensor.
Output 4 - 20mA (three-wire connection).
Power supply 9 Vdc 40 Vdc for the model HD 9008T.
Output 0 - 1 Vdc. Power supply 5 - 35 Vdc for the model HD 9009T.
Both the models are an inbloc relative humidity and temperature transmitters.
The sensors are fitted at the end of a plastic material tube and are protected against dust by a
stainless steel filter.

SIGNAL TRANSMISSION
The electronic circuit is designed in such a way that there is a linear increase of the signal as humidity and temperature increase. In the presence of cables transmitting strong currents or machines that provoke electromagnetic disturbances, the transmitter connection cables must be laid in a separate channel or at a certain distance so that the disturbances are screened.
INSTALLATION
Precision of measurement does not depend on the position of the transmitter; minimize the accumulation of dust on the stainless steel filter. The transmitter must not be installed in the immediate vicinity of a source of heat, as the heating of the air leads to a decrease of the relative humidity (with the same amount of water vapor present) close to doors or draughts.
ASSEMBLY
The electronics are housed in a sturdy plastic material container (degree of protection 1 P 54).
For the connections, see the drawings and diagrams. Once installation is complete, cheek that the
container is perfectly closed; the same applies to the grommet.
