1 Series 0EX series transmitters from Automatikprodukter are designed for the accurate measurement of humidity and temperature in the range between 0...0% RH and C ( ). Models for pressure tight installations from bar ( psi) complete the range of products. meets the AEX requirements and IECEx standards of intrinsically safe machinery: Humidity/emperature ransmitter for Intrinsically Safe Applications Applied standards for AEX: Applied standards for IECEx: EN0014:17 IEC 007-0:2004 EN0020:14 IEC :1 EN0284:18 IEC 007-2:2004 Model A he EC type examination was carried out by Physikalisch- echnische Bundesanstalt (PB), the German national institute for science and technology. he transmitters of series consist of: - supply and evaluation unit, classified according to II (1) G [EEx ia] IIC subject to EC-type examination certificate PB AEX 2042 and [EEx ia] IIC according to IECEx PB sensor driver unit and sensor probe, classified according II 1/2 G EEx ia IIC subject to EC-type examination certificate PB AEX 204 X and EEx ia IIC according to IECEx PB 0.002X. Model D he sensor probe can be employed in zone 0 and in temperature class (apparatus group II, category 1). or versions D and E the cable length between sensing probe and sensor driver unit can be up to m (2.8ft). he maximum length of the cable between the supply and evaluation unit and the sensor driver unit is 0m (28ft). he analogue output signals for humidity and temperature Model E are available as current or as voltage. State-of-the-art microprocessor technology makes both analogue outputs free selectable and scaleable via RS22 serial interface. Besides measurement of humidity and temperature series calculate the values of the following physical quantities: - dew point temperature d - frost point temperature f - wet bulb temperature w - water vapour pressure e - mixing ratio r - absolute humidity dv - specific enthalpy h hese are available on the RS22 serial interface, on the analogue outputs and on the integrated LC display. he communication with a PC is assisted by an user friendly software, running under MS Windows M which enables the user to change original factory settings easily. v2.2 12

4 Working RangR ange e Humidity Sensor relative humidity [%RH] he 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. temperature [ C] Sensing head with protecti otective e coating or 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 of the resistance to chemical pollutants which leads to a much better long term stability of the transmitter.
