1 General
This operation manual serves for ensuring proper handling and optimal functioning of the device. The
operation manual shall be read before commissioning the equipment and it shall be provided to all staff
involved in transport, installation, operation, maintenance and repair.
The operation manual may not be used for the purposes of competition without the written consent of
E+E Elektronik® and may not be forwarded to third parties. Copies may be made for internal purposes.
All information, technical data and diagrams included in these instructions are based on the information
available at the time of writing.
Intended use
The EE211 is intended for the measurement of relative humidity (RH) and temperature (T) in
environment with continuous high humidity. The use of the EE211 other than described in this manual is
not recommended.
The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation
and maintenance of the device. Unauthorized modifications of the product lead to loss of all warranty
claims. The device may only be powered with separated extra-low voltage (SELV).
Disclaimer
The manufacturer or his authorized agent can be only be held liable in case of willful or gross
negligence. In any case, the scope of liability is limited to the corresponding amount of the order issued
to the manufacturer. The manufacturer assumes no liability for damages incurred due to failure to
comply with the applicable regulations, operating instructions or the operating conditions. Consequential
damages are excluded from the liability.
1.1 Explanation of Symbols
This symbol indicates safety information.
It is essential that all safety information is strictly observed. Failure to comply with this information can
lead to personal injuries or damage to property. E+E Elektronik® assumes no liability if this happens.
This symbol indicates instructions.
The instructions shall be observed in order to reach optimal performance of the device.
1.1.1 General Safety Instructions
• The sensor and mainly the sensing head of the probes shall not be exposed
to extreme mechanical stress.
• Installation, electrical connection, maintenance and commissioning shall be performed by
qualified personnel only.
• Use the EE211 only as intended and observe all technical specs.
• Make sure that the T Probe is properly connected. The absence of the T probe forces the analogue
outputs into the upper limitation.
• The sensor must be operated with the filter caps on at all times. Do not touch the sensors inside the
sensing head.
• While replacing the filter cap (because of pollution for instance) against an original spare one please
take very good care to not touch the sensors.
1.2 Environmental Aspects
Products from E+E Elektronik® are developed and manufactured observing of all relevant requirements
with respect to environment protection. Please observe local regulations for the device disposal.
For disposal, the individual components of the device must be separated according to local recycling
regulations. The electronics shall be disposed of correctly as electronics waste.

3 Product Description
3.1 Operation Principle
The humidity probe is continuously heated for avoiding the effects of condensation and high humidity onto the sensing elements, such as corrosion, high humidity drift or stray impedances. Thus, the
probe heating leads to outstanding long term stability. Based on the measured values humidity and
temperature, the EE211 calculates the dew point temperature Td whereas the separate, interchangeable T-probe measures the ambient temperature. Ultimately, out of Td and T, the device calculates the
relative humidity RH as well as several other parameters like absolute humidity, mixing ratio, wet bulb
temperature or enthalpy.
