Datasheet

 

The TW is dew point (condensing) sensor for use in air ducts, heating and aircondition.

  • HVAC systems – cooling panels, cold-water piping, metal construction,

   which must be protected against condensate

The TW reliably detects formation of condensation by means of its humidity and temperature
sensor (no conductivity measurement). Thanks to its measuring method
yields an exact measurement result and helps preventing formation of condensate.
Dew point temperature is a temperature at which air reaches the state of saturation
and water starts to precipitate. The output of the sensor switches extra heating to
protect the construction from damage or limits cold water supply temperature to prevent
condensation.
The sensors are intended for operating in normal, chemically non-aggressive environment.
They do not need any servicing or maintenance and can be mounted in any
position. It is strongly recommended mounting sensors horizontally, with body facing
upwards.
