Intrinsic safety explosion protection is an electric circuit and a construction, which
made so as not to ignite to gas by controlling the energy of electric circuit, if sparks,
arc, and heat occur at the time of normal operating and an accident (short-circuit, earth
fault, burnout). Intrinsic safety explosion protection equipments include intrinsic safety
equipments and equipments related with intrinsic safety. Intrinsic safety equipments are
able to be used in hazardous area. Equipments related with intrinsic safety are set up in
non-hazardous area, and is connected with intrinsic safety equipment.
In CENTUM, intrinsic safety explosion protection instrumentation can be done by building
Zener barrier or insulating barrier into it.
