The highly accurate humidity/temperature transmitter EE33 is 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. Distinctive models and mounting versions allow the humidity/temperature transmitter EE33 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 core of the humidity/temperature transmitter EE33 is the humidity sensor HMC01. This monolithic measurement cell is manufactured in thin-film technology. Chemical contamination and also condensation will actually evaporate due to the innovative design of the HMC01 humidity sensor. The monolithic construction of the sensor allows a fast return to normal conditions and a continuation of the measurement.Additionally sensor coating the HMC01 humidity sensor is even better protected against corrosive and short-circuit-causing conductive soils. 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.
