EE30EX humidity transmitters meet the ATEX requirements and IECEx standards and comply the health and safety standards of intrinsically safe machinery.
The EC type examination was carried out by Physikalisch - Technische Bundesanstalt (PTB), the German national institute for science and technology.
The humidity transmitter EE30EX consist of:
-
EE30EX supply and evaluation unit, classified according to II (1) G [Ex ia] IIC subject to EC-type examination certificate PTB 99 ATEX 2042 and [Ex ia] IIC according to IECEx PTB 05.0031-1.
-
Sensor driver unit and sensor probe, classified according II 1/2 G Ex ia IIC T6 subject to EC-type examination certificate PTB 99 ATEX 2043 X and Ex ia IIC T6 according to IECEx PTB 05.0032X-1.
Besides measurement of humidity and temperature the EE30EX calculates the values of the following physical quantities:
-
dew point temperature Td
-
frost point temperature Tf
-
wet bulb temperature Tw
-
water vapour pressure e
-
mixing ratio r
-
absolute humidity dv
-
specific enthalpy H
These are displayed on the RS 232 serial interface, on the analogue outputs and on the integrated LCD display.
There are three models available:
-
Model A: wall mounting in explosive zone 1 or 2
-
Model D: separated sensor head for installation directly in the partition wall
-
Model E: separated sensor head for high pressure environment (0.01...15 bar)
