ATEX IECEx Compliant Cover

ATEX – IECEx Certification

Rheonics is pleased to announce the release of its ATEX & IECEx certifications. The new certifications project started with the goal to better serve our worldwide customers.

As a long time manufacturer of fluid-sensing solutions, Rheonics is continuously identifying and designing new solutions and protections that our customers will trust in their hazardous and explosive locations.

ATEX & IECEx Compliance

Rheonics offers intrinsically safe sensors certified by ATEX and IECEx for use in hazardous environments. These sensors comply with the essential health and safety requirements relating to the design and construction of equipment and protective systems intended for use in potentially explosive atmospheres.

The intrinsically safe and explosion proof certifications held by Rheonics also allows for customization of an existing sensor, allowing our customers to avoid the time and costs associated with identifying and testing an alternative. Custom sensors can be provided for applications that require one unit up to thousands of units; with lead-times of weeks versus months.

Rheonics SRV & SRD are both ATEX and IECEx certified by TÜV Rheinland.
