The Austrian sensor specialist E+E Elektronik has won the contract from the Deutscher Wetterdienst - DWD (National Meteorological Service of Germany) to equip its weather stations with new humidity/temperature transmitters.
The humidity/temperature transmitters in use here are the EE33 series (type J). The devices feature high-precision and reliable measurement results even under the most challenging of ambient conditions. At the heart of this transmitter is the monolithic HMC01 measurement cell developed by E+E using thin-layer technology. Thanks to the unique E+E sensor coating, the measurement cell is optimally protected against condensation and chemical contamination. This was a factor that also persuaded the Royal Netherlands Meteorological Institute (KNMI) to procure these transmitters for themselves.
Previously humidity and temperature were each recorded using a separate transmitter. With the new humidity/temperature transmitters from E+E Elektronik, both these measurements can now be taken using a single instrument. A further benefit: measurement results will in future be transmitted digitally, not via analogue means.
All instruments are manufactured in Engerwitzdorf (A). The first hundred transmitters are scheduled to ship during August 2013.
E+E Elektronik itself operates a state-accredited calibration lab and holds the National Standards for relative air humidity and air flow velocity in Austria on behalf of the Bundesamt für Eich- und Vermessungswesen - BEV (Austrian Federal Office for Metrology and Surveying).
• E+E products are marketed in Ireland by Instrument Technology.
