This early-warning dew-point switch is designed for use in monitoring cooling water pipes or chilled surfaces in order to determine if temperatures are approaching the dewpoint. It is suitable for mounting on flat and round surfaces. The switch measures the relative humidity prevailing directly at the chilled surface and can thus be used to:
regulating cooling performance
switching cooling systems ON and OFF
signalling if the temperature is approaching the dew-point
Status indication with LED, showing condensation danger
Switching point at 90 %rh, hysteresis 5 %rh
Ambient temperature 0 ... 50 oC
Power supply 24 Vacdc | 0.3 VA 
Switch function/capacity potential free changeover contact; max. 24 Vac/dc, 1 A
Mounting place strap on pipe
Protection class IP40
