Safety First: Gas monitoring in industrial ATEX environments


ATEX gas sensors from MSR-Electronic protect EX areas according to legal regulations

Wherever combustible liquids or gases are processed in industry, explosive air mixtures can occur.

In production, transport and storage – in many branches of industry, such as the chemical industry, oil and gas production, H2 mobility and in the marine and offshore sector.






Why is permanent gas monitoring necessary?

When handling hazardous substances, special protective measures are imperative. MSR-Electronic protects the health of employees and equipment there under extreme industrial conditions. The protection of people requires constant monitoring and measurement of toxic and combustible gases and vapours. Furthermore, continuous monitoring for oxygen deficiency and excess must take place.

How is permanent gas monitoring carried out?

MSR-Electronic has a wide range of methods for the permanent detection of gases. On this basis, MSR develops individual gas sensors, controllers and warning devices for industrial applications where extreme environmental conditions prevail. Of course, this also applies to Ex zones 1 and 2.


In addition, MSR-Electronic has the following necessary approvals:

Gas detection with ATEX gas sensors using the example of H2 research, H2 production, H2 transport

or H2 mobility


The areas of application for hydrogen as an energy carrier of the future are numerous. Besides its use in welding or as fuel for rockets, the focus is currently mainly on the automotive sector. Hydrogen combustion engines or fuel cells are expected to replace fossil fuels in the foreseeable future.

H2 is a very reactive gas, which makes continuous monitoring by an H2 gas alarm system throughout its life cycle imperative. Leaks can occur at any time during research work, on test benches and during the production of the gas. This would cause catastrophic damage in the event of ignition. Gas detectors must also be used during transport and at filling stations.

The SIL2 certified PolyXeta®2 product series from MSR-Electronic makes it possible to place only the ATEX-certified sensor head in the hazardous zone and to lead it with the associated ATEX cable out of the hazardous zone to a board or controller to carry out the evaluation of the sensor there.


Thanks to the X-Change technology, calibration can be carried out by simply exchanging the gas sensor or by using the integrated, convenient calibration routine directly on the system.
