Use
The duct temperature sensors are for use in ventilation and air conditioning plants as:
● Supply or extract air temperature sensors
● Limit sensors, e.g. for minimum limitation of the supply air temperature
● Reference sensors, e.g. for shifting the room temperature as a function of the outside
temperature
● Measuring sensors, e.g. for measured value indication or for connection to a building
automation and control system
Function
The sensor acquires the air temperature via its sensing element whose resistance changes
as a function of the temperature. The signal is delivered to a suitable controller for further
handling.

Mechanical design
The duct temperature sensor consists of the following components:
● Two-sectional plastic housing comprised of base with connection terminals and
removable cover (snap-on design)
● Immersion rod complete with sensing element
The connection terminals can be accessed after removing the cover.
