YOUR PARTNER IN SENSOR TECHNOLOGY EE30EX Humidity/Temperature Transmitter for Intrinsically Safe Applications EE30EX series transmitters from E+E Elektronik are designed for the accurate measurement of humdity and temperature in the range between 0...100% RH and -40...180°C (-40...356°F). Models for pressure tight installations from 0.01...15 bar (0.15...218psi) complete the range of products. EE30EX meets the ATEX requirements and IECEx standards of intrinsically safe machinery: Applied standards for ATEX: Applied standards for IECEx: The EC type examination was carried out by Physikalisch-Technische Bundesanstalt (PTB), the German national institute for science and technology. The transmitters of EE30EX series consist of: - EE30EX supply and evaluation unit, classified according to II (1) G [Ex ia Ga] IIC subject to EC-type examination certificate PTB 99 ATEX 2042 and [Ex ia Ga IIC according to IECEx PTB 05.0031-2. - sensor driver unit and sensor probe, classified according II 1/2 G Ex ia IIC T6 Ga/Gb subject to EC-type examination certificate PTB 99 ATEX 2043 X and Ex ia IIC T6 Ga/Gb according to IECEx PTB 05.0032X-2. The sensor probe can be employed in zone 0 and in temperature class T6 (apparatus group II, category 1). For EE30EX versions D and E the cable length between sensing probe and sensor driver unit can be up to 10m (32.8ft). The maximum length of the cable between the supply and evaluation unit and the sensor driver unit is 100m (328ft). Model A Model D Model E The analogue output signals for humidity and temperature are available as current or as voltage. State-of-the-art microprocessor technology makes both analogue outputs free selectable and scaleable via RS232 serial interface. Besides measurement of humidity and temperature EE30EX series calculate the values of the following physical quantities: - frost point temperature Tf - water vapour pressure e These are available on the RS232 serial interface, on the analogue outputs and on the integrated LC display. The communication with a PC is assisted by an user friendly software, running under MS WindowsTM which enables the user to change original factory settings easily.

Configuration Software_ The Configuration Software is used for: - flexible, easy, and fast setup of the analogue outputs resp. of the RS232 serial interface. - adjustment of the humidity and temperature outputs.

Working Range Humidity Sensor relative humidity [%RH] The specified working range for the humidity sensor element is shown in terms of humidity/temperature limits. Although the sensors would not deteriorate beyond the limits, their performance can only be specified within the limits for the working range. Sensing head with protective coating For use in heavy polluted or aggressive environment E+E has developed a special protective coating process (order code: HC01). Both humidity and temperature sensor elements are covered with a polymer film. Extensive tests have proved an amazing improvement...
