EE22 EE22

Humidity / Temperature Transmitterwith interchangeable probes

Unique for the EE22 series are the interchangeable sensing probes with connector. The calibration data is stored in the probes, which are therefore interchangeable and probe replacement does not affect the performance of EE22. The outstanding accuracy over the entire temperature range is based on very precise calibration methods and on the latest microprocessor technology. Well-proven E+E humidity sensor elements ensure excellent long-term stability. For high temperature applications (up to +80°C /
+176°F )or in caseof limited space availability, the sensing probes can be connected to EE22 housing with cables (2m, 5m or 10m / polycarbonatehousing metal housing
6.6ft, 16.4ft or 32.8ft )without any repercussions for the overall accuracy of the instrument.Voltage 0 - 1 / 5 / 10V or current 4 - 20mA(2 wire) outputs are available, of which the temperature output can be scaled according to the application (see ordering guide).EE22 is suitable for direct wall mounting and for installation onrails according to DIN EN 50022. The optional display indicates the actual RH and Tvalues. In the pharmaceutical and biotechnology industry a Loop-Calibration of the RH and Toutputs, recommended by the FDA(Food and Drug Administration), can easily be performed utilizing separate RH and Tprobes (Type: EE22-xFTx2x).The RH and Toutputs can be adjusted with push buttons on the printed circuit board.

As useful accessories reference probes (incl. test report) representingfixed humidity and temperaturevaluesare available. They shall be installed instead of the measuring probes to checkfunction and accuracy of the evaluation unit.One probe simulates high humidity and low temperature, the other low humidity and high temperature, to check the upper and lower end of both analogue outputs.
