With the innovative measuring principle and the use of a special sensor with logarithmic characteristics, it is possible to control closely to the dew point  threshold without risking condensation. The dew point controller can be mounted directly and simply on pipes with the corresponding diameter. It is completely sealed so the electronics are optimally protected.

Areas of application:

  • For cooling ceilings to prevent condensation
  • For indoor pools and shop display windows to keep the double glazing fog-free and prevent steaming-up.
  • In drinking water and industrial plants to detect „sweating“ of cold pipes
  • In Hypermarkets, Concourses, Halls, Greenhouses and Storage facilities, to detect condensation formation on cold outdoor walls, steel doors, or to protect the stonework and masonry
  • In switch cabinets or in machines, to detect condensation on sensitive electronic components 
  • For humidity and leakage detectors
  • It can be integrated into alarm or warning systems ( by the relay / opener ) 
  • In submersible pumps for detecting leakage
Other diameters are possible on request.
