Standex-Meder Electronics announces its new ATEX optocoupler for intrinsically safe circuits. The optocoupler series are tested and certified for extreme/harsh environments such as potentially ...

Site operators sometimes ask about how to make their equipment intrinsically safe. For example, one firm inquired about how to make its 480V motors intrinsically safe. Such a lack of understanding of ...

Intrinsically safe circuits are designed so that there is insufficient energy in the power supply to cause local heating or a spark that could ignite an inflammable gas. There are two main levels of ...

The IECEx is a certification system which verifies compliance with IEC international standards relating to equipment for use in explosive atmospheres. The safety requirement for equipment under IECEx ...

If you’re responsible for overseeing operations in high-risk industries like oil and gas, mining, or chemical manufacturing, you know the threat of accidents in explosive atmospheres is ever-present.

North American companies are beginning to move toward intrinsically-safe systems, already well established in Europe, that use currents and voltages too low to spark an explosion in a hazardous ...

Article 501 through 503 form a trilogy. Art. 505 provides an alternative to Art. 501; Art. 506 provides an alternative to Art. 502 and 503. Between these two sets is Art. 504. It’s sandwiched there ...

THERE is an urgent need for a comprehensive theoretical correlation between the constants of a complex circuit and its intrinsic safety in the presence of inflammable gases. This has not yet been ...
