Measurement principle
The temperature humidity sensors are compact sensors in a rod-
design with plug-in connection to measure relative humidity and
temperature (individually or together) with high precision in air an
other non-aggressive gases. The delivery includes the coupling
plug.
The relative humidity is measured by a capacitive sensing element
and the value will be placed at the output as analog output as well.
Temperature Humidity Sensor
Mounting
The sensors are to be mounted at a climate representa-
tive spot. For protection against rain and direct radiation a
weather and radiation shield should be used, which can be
simply  xed to a mast.
Please order the weather and radiation shield separately!
Take care of a good ventilation of the sensing element. any
mouting position is possible. Avoid penetration of water.
Dew-formation does not do any harm to the element, but
faulty measurements will occur until total drying.
Maintenance
The temperature sensor is maintenance-free. Only check
the output after long use with a precise reference ther-
mometer.
It is possible to make functional gauging of the humidity
sensor. To do this, the sensor has to be exposed to a known
reference humidity, e.g., the available “humidity-standard”
calibration set. If you unscrew the protection  lter, keep in
mind never to touch the element with  ngers or any tool.
