Application; Mounting - Thies CLIMA Hygro-Thermo Transmitter-compact Instructions For Use Manual

2 Application

The Hygro-Thermo Transmitters of our compact series are designed to measure relative humidity,
the temperature of the air and other non-aggressive gases.
The use of capacitive humidity sensors is a guarantee for:
•
a high degree of long-term stability
•
nearly linear characteristics
•
good dynamic behaviour
•
dewing stability
•
low temperature coefficients
•
low hysteresis
The hygro-thermo transmitter is equipped with a protective filter for the sensors.
Type: Membrane-filter with gauze ZE20 (order-no. 1.1005.54.901) for protection against
dust in case of field application.
Remark:
For filed work, it is advisable to use a „Weather and Thermal Radiation Shield". It
is optionally available as accessory.

3 Mounting

For correct measurements, the Hygro-Thermo Transmitter should be mounted at a site in the room
which is representative of the climate within the room. The mounting position itself is arbitrary.
Mount the sensor such that water cannot penetrate the inside of the sensor. Dewing and sprinkling
water do not damage the sensor.
Moreover, please make sure to keep the operating voltages as well as a good recirculation
ventilation of the instrument. Deviations might lead to measurement errors (for example: due to
instrument warming).
Preferably, the sensor should be mounted vertically facing downwards to a wall (indoor application),
and should be mounted horizontally facing backwards in canals.
