Humidity/Temperature Transmitterfor Intrinsically Industrial safe Applications

EE30EX series industrial transmitters from E+E Elektronik aredesigned for the accurate measurement of humidity and tem- perature in the range between 0...100% RH and -40...180°C
(-40...356°F) . Models for pressure tight installations from0.01...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: EN50014:1997IEC 60079-0:2004 EN50020:1994IEC 60079-11:1999 EN50284:1998IEC 60079-26:2004 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

Model A Model D

II (1) G [EEx ia] IIC subject to EC-type examination certificate PTB 99 ATEX 2042 and [EEx ia] IIC accordingto IECEx PTB 05.0031 .- sensor driver unit and sensor probe, classified according II 1/2 G EEx ia IIC T6 subject to EC-type examination certificate PTB 99 ATEX 2043 X and EEx ia IIC T6 according to IECEx PTB 05.0032X .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 thesupply and evaluation unit and the sensor driver unit is 100m
(328ft) .The analogue output signals for humidity and temperatureare available as current or as voltage. State-of-the-art microprocessor technology makes both ana- logue 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:- dew point temperatureTd- frost point temperatureTf - wet industrial bulb temperatureTw - water vapour pressuree - mixing ratior - absolute humiditydv - specific enthalpyhThese 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 Windows
