TW-W-External 75...100% rH, Changeover contact Dew-point sensor

The dew point monitor HYGRASGARD~ TW is mounted on cooling & cold water pipes or on chilled surfaces. The TW has a very reliable measurement method, thanks to the temperature and humidity sensor (no conductivity measurement). Together with the rectangular convector operation, this provides an exact measurement result. The dew point temperature is the temperature at which air reaches its saturation point and condensation occurs. Due to the adjustable limit value 75°100% on the TW-W, cooling ceilings, for example, can be controlled in such a way that the switching output of the dew point monitoring is activated before condensation occurs, enabling intervention. For example, a heating element can be switched on which prevents condensation. Humidity is measured with a digital, long-time stable humidity/temperature sensor.
