2.7.4 Combination Temperature/
Humidity Sensor
HTH-6202 sensors are installed in the ventilation
duct using the accompanying bracket, which must
be attached to a firm, level surface by means of
two screws. The 18-30 V DC supply voltage (24 V
DC nominal voltage) is provided via the Modbus
connection. HTH-6202 has a pre-fitted 7000 mm
cable, which is equipped with a standard RJ12
connector. The cable may be extended to as much
as 50 m without any negative eects on measuring
accuracy. The surrounding EMC environment must,
however, be taken into account and must be capable
of being defined as low. To extend the cable, use a
crossover Category 3 extension cable, RJ12-RJ12,
6P6C. The sensor should be installed in such a way
that the air flow in the duct can pass unhindered
through the measuring hole at the end of the sensor,
which should be aligned parallel to the air flow.
Although HTH-6202 is not aected by the position
in which it is installed, it is advisable not to install
the sensor in an upright position with the cable
downwards as this may cause moisture to accumulate
in the sensor. It is important that HTH-6202 is installed
in such a way that the measuring hole is positioned at
the center of the duct.
