E+E EE33 Specifications

EE33
Humidity / Temperature Transmitter for
High Humidity and Chemical Applications
The highly accurate EE33 series are designed for fast and reliable measurement of relative humidity / dew point temperature / absolute humidity / ...under the most demanding conditions. Neither condensation nor heavy chemical pollutions will affect prompt and reliable measurements. Process pressures as high as 100 bar continuous high humidity are also no problem for the EE33 series. The core of the EE33 series is the new monolithic measurement cell type HMC01, manufactured in thin-film technology by E+E Elektronik. Chemical contamination and also condensation will actually evaporate due to the innovative design of the HMC01 measurement cell. The monolithic construction of the sensor allows a fast return to normal conditions and a continuation of the measurement. Additionally, with the inimitable E+E sensor coating the HMC01 measurement cell is even better protected against corrosive and short-circuit-causing conductive soils. Distinctive models and mounting versions allow the EE33 series to be utilized in numerous applications:
- Measurement of relative humidity during temporary condensation: the measurement cell is briefly heated, but very intense
- Measurement of dew point temperature at continuous high humidity: the measurement cell is controlled and heated continuously
- Measurement of relative humidity at continuous high humidity: the measurement cell is controlled and heated continuously; an additional temperature sensor is added
- Measurement of relative humidity at high chemical exposure and
average humidity:
the measurement cell is briefly heated, but very intense
- Measurement of relative humidity at process pressure up to 100 bar
(1450 psi) and average humidity:
the measurement cell is installed in a special high pressure probe
The configuration software included in the scope of supply allows user friendly setup of the operation / sensor heating mode as well as selection and adjustment of the electrical outputs.

Networkability
The optional RS485 interface (order code N) allows for building a network of up to 32 transmitters. The measurement data can be collected in a shared database and made available for all kinds of further processing.
Product Configuration Software (EE-PCS)
The configuration software allows flexible and simple adjustment of the analogue and alarm outputs in accordance with the requirements. The adju­stment / calibration of the humidity and temperature outputs is possible as well. Furthermore the settings of the start and duration of the heating of the measurement cell can be defined.
Integrated Display
The actual measurement data and the corresponding Min/Max values can be indicated in an optional display (order code D05). The physical quantity to be displayed is selected by the push buttons next to the display.
Alarm Outputs
An optional alarm module with 2 relay outputs is available for control and alarm purposes (order code SW). The selection of the physical quantity and the setting of threshold and hysteresis can be made with the configuration software included in the scope of supply.
