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)
