Humidity/Temperature Transmitter for High Humidity and Chemical Applications
E+E Elektronik says that the recently introduced and highly accurate E+EE32/33 series of instruments is designed for fast and reliable measurement of relative humidity, dew point temperature and absolute humidity under the most demanding conditions.
Neither condensation nor heavy chemical pollutions will affect prompt and reliable measurements, says E+E. Process pressures as high as 100 bar (1450 psi) and continuous high humidity are also no problem for the EE32/33 series.
Distinctive models and mounting versions allow the EE32/33 series to be used 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 (EE33 only): 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 core of the EE32/33 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, explains the company. The monolithic construction of the sensor allows a fast return to normal conditions and a continuation of the measurement.
Additionally, with the special E+E sensor coating, the HMC1 measurement cell is even better protected against corrosive and short circuit-causing conductive soils.
The configuration software included in the scope of supply allows user friendly set-up of the operation and sensor heating mode as well as selection and adjustment of the electrical outputs.
