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 (1450 psi) and
continuous high humidity are also no problem for the EE33 series.
The core of the EE33 series is the new monolithic measurement cell type
HMC1, manufactured in thin-film technology by E+E Elektronik.
Chemical contamination and also condensation will actually evaporate due to
the innovative design of the HMC1 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 HMC1 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 100bar (1450psi)
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.
