当物体表面周围的空气相对湿度(RH)达到99%RH时,表面会发生冷凝. 依靠与表面非常好的热耦合,EE046可精确测量表面温度下的空气相对湿度.
在冷凝实际发生之前,继电器输出会在接近冷凝条件时发出预警. 该产品还会提示电源故障或电缆损坏. 状态LED灯指示正常运行,冷凝危险或电源故障.E+E涂层保护湿度敏感元件免受灰尘和污染物影响.

供电The device measures the relative humidity at the surface to be monitored and provides an early warning signal (relay) when the humidity reaches 90% RH.
The signal can be used for initiating control steps such as increasing the water temperature in a chilled ceiling, reducing the cooling capacity or switching on the heating.A special coating protects electronics and sensor against contamination.
