USER INFORMATION

Temperature/humidity sensor,
in shelter,
incl. 5 m connection cable

3033.0000

INSTALLATION

Temperature/humidity sensor,
in shelter,
with measuring converter 4...20 mA
incl. 5 m connection cable

3033.0200

The sensors are to be attached in a position representative for the climate measurement.
The installation position of the sensor must be ensured
in accordance with the photo on page 1. However,
it should be mounted in such a way that no water can
get into it.

CALIBRATION AND MAINTENANCE
Calibration and maintenance of the probe should be
performed at regular intervals, at least once a year or
more often, depending on the conditions of use and
desired accuracy.

Dust and other solid particles do not damage the humidity sensor element, however, if there is an accumulation of dust on it, the dynamic behaviour could be
impaired.
If it should become necessary to clean it, the filter can
carefully be unscrewed and rinsed. Loose dirt can also
be removed from the measuring element by blowing it
off or rinsing it carefully with distilled water.
Dew formation and splashes do not damage the sensor, although corrupted measurement readings are
recorded until all the moisture on and directly around
the sensor element has dried up.
DAMAGING INFLUENCES
Agents that are corrosive and contain solvents, depending upon the type and concentration of the agent,
can result in faulty measurements and cause the
measuring element to break down.
Substances deposited on the sensor are damaging as
they form a water-repellent film (this applies to all humidity sensors with hygroscopic measuring elements);
e.g. resin aerosols, lacquer aerosols, smoke deposits
etc.

REPLACING OF SENSOR
Loosen fixation screw. Pull sensor out of its socket and
replace it by a new one. Sensor has to be touched
carefully, at its plastic shaft.
