Intrinsic safety (IS)

Design-based explosion protection reduces the risk of explosion

A hazardous location is where concentrations of flammable gases, vapors or dusts are present. Electrical equipment installed in such locations must be specially designed and tested to ensure they do not increase the risk of an explosion. Our instruments are covered by international certifications (IECEx, ATEX, CSA, FM, NEPSI) with various protection types such as intrinsic safety, explosion protection (flameproof) and non-incendive design approaches to meet various risk requirements

Intrinsically safe instruments for hazardous locations

Our instruments are certified for the most critical gas groups and temperatures. They can be applied up to zone 0 (gas) and zone 20 (dust). Based on the principle of limiting the current and voltage in a circuit, we offer a consistent range of intrinsically safe devices. Even for flow, you can rely on stable and safe measuring results with our intrinsic safe two wire instruments for all important measuring technologies like Coriolis, electromagnetic and ultrasonic.

Efficient and safe maintenance

Intrinsically safe instruments can be maintained or replaced during operation. A hot work permit is not necessary. In addition, our certified modular spare part concept enables flexible and secure operation and keeps your costs to a minimum.

Different standards and legislations per countries

Depending on the country, you can find different applicable standards and legislations for explosion protection as for example: ATEX for Europe, NEPSI for China, IECex for Australia, FM for the Unites States and CSA for Canada. Countries with no specific certification recognize the ones above.
