Explosion proof

EX – intrinsic safety

MESCO considers the explosion-proof requirements with the beginning of the concepts until compilation of the manufacturing documentation. This task will cut development time and production cost. A retroactive action for the Ex task is not applicable and saves time and money. Especially for cost sensitive products is this the important factor for the success.

Explosion protection is an essential factor for operation in process automation. MESCO therefore offers its own safe explosion proof solutions (conforming to international standards such as IECEx, ATEX, FM, CSA etc.).

Our services

We implement sensors and actuators with functional safety functions (SIS / SIF) according to the relevant standards such as IEC61511 / IEC61508 or EN50271 / EN50402.

Additional flexibility comes with the introduction of Single Pair Ethernet (SPE) with Power Over Data Line (PoDL), which makes proven communication technology suitable for the special requirements of PA. As an alternative to HART and fieldbus communication, MESCO offers the integration of SPE and APL. This opens up IIoT functionality, predictive detailed diagnostics, functionally safe communication, regardless of the local power supply.
