Humidity measurement module for OEM applications
Aug 14 2018 Read 317 Times
The EE1900 humidity module from E+E Elektronik is optimised for the measurement of relative humidity (RH) or dew point temperature (Td) in climate and test chambers. With outstanding 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 wide range of applications.
The excellent measuring accuracy of the EE1900 rests on the innovative E+E humidity and temperature sensing element HMC01. The proprietary E+E coating protects the sensor from dust, dirt and corrosive agents. Therefore, the EE1900 module features excellent long-term stability even in harsh environment.
Thanks to the Automatic Sensor Recovery (ARC) function, the sensor copes well with chemical contamination. By controlled, strong heating, the chemicals gaze out from the sensing element. After the ARC cycle, the sensor quickly 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 analogue 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 high quality, 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 ʺ or 90 x 70 mm / 3.54 x 2.76 ʺ), the humidity measurement module can be easily integrated into existing climate chambers.
