Intrinsically Safe for Hazardous Areas

The phrase "Intrinsically Safe" is often used generically to describe products destined for hazardous (explosive) areas. This post explores the term "Intrinsically Safe", provides an overview of what is required to certify a product and …

CSA/ATEX Intrinsically Safe: Meaning

Intrinsic Safety (IS) is based on the principle that the electrical energy in hazardous-area circuits is deliberately restricted such that any electrical sparks or hot spots that may occur are too weak to cause ignition. This is …

Intrinsic Safety Control Drawing

The criterion for such interconnection is that the voltage (Ui), the current (Ii) and the power (Pi) which intrinsically safe apparatus can receive and remain intrinsically safe, considering faults, must be equal or greater than the voltage (Uo), the current (Io) and the power (Po) which can …
