Early Warning Dew-Point Switch
The HSS-DPS early-warning dew point switch is used to monitor the formation of condensation on chilled ceilings or to prevent condensation at critical spots of HVAC systems.
Overview
The dew point switch measures the relative humidity near the dew point using its high-quality capacitive sensor. At reaching the switching point the output will provide an early warning signal for the initiation of control steps (increasing the initial water temperature, reducing the cooling capacity, switching on the heating, etc.). An additional status light indicates the condensation danger, as well as indicating power supply failure or broken cable. Thanks to the special protection coating, sensor and electronics are highly insensitive to dust and dirt. HSS-DPS dew point switch can be mounted on walls, ducts and pipes up to 50 mm (2“)
