v1.3 / Modification rights reserved | 2 EE046 The EE046 condensation monitor helps to prevent condensation on critical cold spots. With the help of its relative humidity (RH) sensing element, it reliably detects the danger of condensation just before it occurs. Mounting Options The EE046 is available in two variants. The wall / pipe mount type is appropriate for installation on flat surfaces and on pipes with a maximum diameter of 50 mm (2”). It is mounted on cooling ceilings, on cooling or cold water piping, cooled surfaces and chilled beams. The snap-on type can be mounted on plastic and aluminium composite pipes with 16 mm or 20 mm diameter. It’s typical applications are cooling and heating by concrete core activation. Reliable Anti-Condensation Safe Guard Condensation on a surface occurs when the relative humidity of the air close to the surface reaches 100 %RH. Because of the very good thermal coupling with the surface, the EE046 measures the RH of the air directly at surface temperature. Its properties make it the ideal choice for applications where control guards are required to prevent dripping or mould. Early Detection of Condensation Risk The relay output provides an early warning before condensation actually happens. It also indicates a power supply failure or a broken cable. A status LED indicates normal operation, alarm or power supply failure.The E+E proprietary coating protects the humidity sensor against dust and dirt.

v1.3 / Modification rights reserved | 4 The E+E proprietary sensor coating is a protective layer applied to the active surface of the sensing element. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive environment (salts, off- shore applications). Additionally, it improves the sensors’ long term stability in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface.
