July 27, 2018 - The EE1900 humidity module from E+E Elektronik is optimized for the measurement of relative humidity (RH) or dew point temperature (Td) in climate and test chambers. With temperature compensation across the working range from -70 °C to 180 °C (-94 °F to 356 °F) and the choice of stainless steel and plastic probes, the module is suitable for a range of applications.
The measuring accuracy of the EE1900 rests on the E+E humidity and temperature sensing element HMC01. The proprietary E+E coating protects the sensor from dust, dirt and corrosive agents.
Thanks to the Automatic Sensor Recovery (ARC) function, the sensor copes with chemical contamination. By controlled, strong heating, the chemicals gaze out from the sensing element. After the ARC cycle, the sensor returns to normal measurement conditions. The ARC mode can be triggered either via a push button on the board or an electrical signal.
The EE1900 module features an analog output, which can be set to current or voltage with a slide switch. The service interface allows for output scaling and adjustment of the humidity measurement. The product configuration software EE-PCS is available free of charge on the E+E website. The operating mode of the module is indicated by status LEDs as well as by the output and status signals.
The EE1900 is available with either stainless steel or plastic (PPS) probe. The flexible probe cable up to 3m length facilitates the probe installation.
With two sizes of the electronics board (55 x 46.5 mm / 2.17 x 1.83 ∫ or 90 x 70 mm / 3.54 x 2.76 ∫), the humidity measurement module can be integrated into existing climate chambers.
