Features of the Integral Measuring Concepts Series IMC
We are often faced with the task to monitor gas concentrations even in sealed off processes or
not accessible areas. Typical applications are for example monitoring of silos and tanks, meas-
urement on dumpsites or biogas plants. Due to the adverse operation conditions direct meas-
urement within theses processes is often impossible. Instead of that sampling from process gas
and external measurement are necessary.
With the Integral Measuring Concepts of the Series IMC ExTox offers efficient solutions even for
these measuring tasks. This Series combines all necessary components from sampling of
measured gas, conditioning, sensor techniques and evaluation in one compact wall mounting
housing.
The IMC includes the control unit ET-8D or ET-4D2 which takes over evaluation of measured
signals and triggering of switching commands. Software expansions in the control unit inte-
grate controlling and monitoring of the components for sampling and conditioning of measured
gas. The measuring channels which are not used for analysis can easily be taken for external
transmitters, for continuous monitoring of ambient air for example.
The modular construction and the use of the approved ExTox-Transmitters and control units
assure a cost effective acquirement and maintenance. ExTox is glad to offer customer specific
types on demand.
The IMC Series can be equipped with all ExTox-Transmitters ExSens(-I) and Sens(-I).
The control units in combination with ExTox-Transmitters comply with EN 60079-29-1 and
EN 45544 for Gas Detection Systems. Furthermore they are in conformity with the European
Directives 94/9/EC (ATEX), 2004/108/EEC (EMC) and 2006/95/EEC (LVD).
