Ten Ways to Design for Intrinsic Safety - Industry Articles

WebAn intrinsic safety (IS) barrier is a safety device that helps to limit energy flow into a hazardous location. IS barriers are often used with traditional two‐wire 4‐20 mA instruments to ensure an intrinsically safe system in hazardous areas. WebJul 15, 2012 · There is no reason why an intrinsically safe device has to be explosion proof. An IS circuit is designed so that it cannot release sufficient energy into a flammable atmosphere to cause ignition - this energy is restricted by limiting voltage and current; and placing upper limits on the total capacitance and inductance in the circuit. cheap flights namibia south africa
