Reliable Condensation Warning
Condensation on a surface occurs when the relative humidity (RH) of the air close to the surface reaches 100 %. The EE046 condensation monitor measures accurately the relative humidity of the air at the surface temperature. An early warning is given via the relay output when this reaches a value of 90 % RH, just before condensation occurs. The relay also indicates a power supply failure or a broken cable. Additionally, an LED indicates the operating status of the EE046 (normal operation / alarm / power supply failure).
Mounting on Surfaces and Pipes
The EE046 condensation monitor is available in two versions. The wall/pipe mount model is appropriate for installation on flat surfaces and on pipes with a diameter of up to 50 mm (2"). It is mounted on cooling ceilings, on cooling or cold water piping, cooled surfaces and chilled beams.
Snap-On Model for Pipes with 16 mm (0.63") Diameter
The snap-on model can be mounted on plastic and aluminium composite pipes with 16 mm (0.63") diameter. Typical applications for this model are cooling and heating by concrete core activation.
Fast Response Time, Long-Term Stable Measurement
Because of the very good thermal coupling with the surface, the EE046 responds very quickly to humidity or surface temperature changes.
The high-quality humidity sensing element is protected against dust and dirt by the E+E proprietary coating. This ensures long-term stable and reliable measurements in harsh and polluted environments.

Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
