E+E EE210 Specifications
EE210
of BACnet International (BI). BTL is a registered trademark of BI.
Humidity and Temperature Transmitter
for Demanding Climate Control
The EE210 transmitter by E+E Elektronik meets the highest requirements in
demanding climate control applications. Besides the accurate measurement
of relative humidity (RH) and temperature (T), EE210 calculates various RH
related parameters such as dew point, temperature, absolute humidity and
mixing ratio. All measured and calculated values are available on the BACnet
MS/TP or Modbus RTU interface, two of them are available on the analogue
voltage or current outputs, while up to three values can be shown simultaneously on the optional display.
Excellent performance of EE210 in polluted or aggressive environment is
ensured by the encapsulated measurement electronics inside the sensing
probe and the long-term stable HCT01 sensor with E+E proprietary coating.
EE210 is available as wall or duct mounted version as well as with remote
probe.The IP65 / NEMA 4 enclosure minimizes installation costs and provides
outstanding protection against contamination and condensation.
With an optional conguration kit, the user can set the RS485 interface parameters, the output scaling and perform one or two
point adjustment for RH and T.

Protective Sensor Coating
The E+E proprietary sensor coating is a hygroscopic layer applied to the
active surface of the HCT01 sensing element. The coating extends substantially the life-time and the measurement performance of the E+E sensor in
corrosive environment (salts, off-shore applications). Additionally, it improves
the sensor’s long term stability in dusty, dirty or oily applications by preventing
stray impedances caused by deposits on the active sensor surface.
