The EE212's sensing head accommodates a sensing module with E+E Elektronik’s latest generation high-precision humidity and temperature sensing element. The proprietary sensor coating and the sealed solder pads improve measuring performance and extend the sensing elements life in harsh environment. The electronics inside the module is encapsulated and therefore best protected against condensation. A wide choice of different filter caps is available for the sensing probe. One major benefit of the EE212 for use in a heavily polluted and aggressive environment is the modular probe design. It enables easy replacement of the sensing module with just a few steps and completely without tools. This means that downtime and service costs can be minimised.
The EE212 can be flexibly adapted to the measurement task for versatile use. In addition to accurate measurement of the humidity and temperature, the sensor calculates various humidity-related parameters such as dew point temperature, absolute humidity and mixing ratio. The measured values are available on two configurable analogue outputs. Three other physical quantities can be displayed on the optional graphic display. Thanks to the free EE-PCS configuration software, the measurands assignments, output scaling and display can be adjusted. A wall version and a duct version of the EE212 are available. The proven HVAC enclosure allows the sensor to be mounted with closed cover. This means that electronics are protected against construction site pollution. The enclosure screws with bayonet closures facilitate fast opening and closing of the cover to complete the electrical installation. For use in the US market, the enclosure features a knockout for a ½" conduit fitting.
