-- &#; For instrumentation, Intrinsic Safety Exi (electronic protection) & Flameproof Exd (mechanical protection) are most common. Intrinsic Safety works on the principle of removing the source of ignition. This can be achieved by using a Zener Barrier or Galvanic Isolator. A zener barrier is a simple device where the voltage is limited by a zener diode and the current by a resistor. The fuse is there to protect …

-- &#; Intrinsic safety is the only protection that considers faults of the field wiring and offers live working without the need for a gas clearance certificate. It does require some design and planning to ensure that the system loop analysis is acceptable. Note: Ex nL has been replaced by Ex ic for zone in the standards. This means intrinsic ...
