Dew-point switch FAS series

Humidity switch for monitoring the formation of condensation - prevents damage caused by condensation or excessive humidity Features • Operating temp. up to 60 °C • Accuracy: ±3 % RH • Long-term stability • Robust • Washable Polyga® measuring element • No external power supply required • Changeover contact with silver contacts Prevent damage By effectively managing condensate, a condensation controller helps prevent water damage, maintain system efficiency, and reduce the risk of indoor air quality issues caused by excessive moisture or air humidity. They are mounted on cooling water pipes or on cooled surfaces and monitor if the temperature drops below the dew-point. They measure the relative humidity to – influence cooling power – switch cooling systems on or off – signal the point at which the temperature drops below the dew-point This makes it possible to operate eg. chilled ceilings optimally even in critical climate conditions, without the formation of condensation. Remarkably straightforward and durable design Protected by the housing, relative humidity near to dew point can form inside. The aluminum plate is adjacent to the cooling pipe and transfers the cold to the water resistant Polyga measuring element. The set point can be set inside and has to be adapted to the local conditions. The microswitch of the hygro module switches a changeover contact potential-free. The standard switch is lined with silver contacts. Optionally there is a microswitch with gold contacts.
