The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation). The accuracy was calculated in accor -
dance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
EE10 is dedicated for accurate relative humidity (RH) and temperature (T)
measurement in residential and commercial HVAC.
The RH and T measured data is available either on two analogue outputs,
or on a BACnet or Modbus RTU interface. A version with analogue RH and
passive T output is also available. The measured data corresponding to the
active outputs can be read locally on the optional display.
Additional physical quantities are available on the Modbus RTU and BACnet
MS/TP interface: absolute humidity, mixing ratio, enthalpy, frost point tem-
perature and water vapor partial pressure.
The stylish enclosure is available in several colors and in two sizes
according to regional standards.
The back cover, which contains only the screw terminals, can be mounted
and wired first. The front cover containing the electronics can be simply
snapped onto the back cover right before commissioning. Thus the active
part of the device is not exposed to construction site pollution and can be replaced without tools within seconds.
