Explosion Protection and Intrinsic Safety 101 Understanding Hazardous Locations and important factor in determining the safety of an electrical circuit is the energy stored in the The Pepperl+Fuchs Engineer's Guide has complete coverage on the European Zone Intrinsic Safety is used to design and implement electrical circuits (mostly Instrumentation or measurement circuits), that will not have any sparking at all. We hope that you liked this short guide on Intrinsic Safety. To get more stuff like this, please subscribe to our mailing list. Intrinsic Safety (IS) is an approach to the design of equipment going into hazardous areas. The idea is to reduce the available energy to a level where it is too low to cause ignition. That means preventing sparks and keeping temperatures low. Intrinsic Safety - The electrical/electronic design includes protection mechanisms limiting the energy available for ignition under any circumstances. This is applicable for electrical/electronic equipment operating at low voltages (example 24 VDC), and not for motors that operate at high voltages. Ten Ways to Design for Intrinsic Safety. environments can contain a wide array of pollutants that can affect the insulation provided between conductive parts of circuits. It's essential to design in sufficient space to maintain the separation of circuits necessary to preserve intrinsic Intrinsic safety is the method of protection for control and instrumentation circuits where the nominal voltage is 24 VDC or less and the current is normally less than 100 mA. The concept of intrinsic safety is to limit the voltage and current so that there is never a spark with enough energy to create an explosion. Intrinsic safety comes with requirements How to design a control circuit for use while keeping barriers in mind. By Dave Perkon, technical editor Even if you are an expert, the standards and requirements change. Take a close look at your standard intrinsic safety system design, and, with a
