A protection applied to electrical equipment in such a way that normal operation is not capable of igniting surrounding explosive atmospheres. The temperature code of a product denotes the maximum surface temperature of the product. Surface temperature of equipment in hazardous areas must be below the self-ignition temperature of the surrounding atmosphere.
A product with temperature code T3 has a maximum surface temperature below o C - provided it is operated within the ambient temperature specified by the manufacturer. The marking differentiates between explosive gas atmospheres, explosive dust atmospheres and the explosive atmospheres in mines susceptible to firedamp.
Approved equipment is marked according to the designed protection concept Ex i, Ex d, Ex n and etc. For the United States it will be preceded by approved Class and Zone.

Protection Techniques Hazardous Areas - North America Dust-ignition proof, explosion proof, instrinsically safe and nonincendive protection of hazardous areas Sponsored Links.
Explosion proof An explosion proof component is capable to keep an internal explosion of a specific flammable air-vapor mixture within the component enclosure without releasing burning or hot gases to the external environment which may be potential explosive. The potentially sparking parts are encapsulated in a special house which is designed to prevent explosions by preventing the entry of hazardous material in potentially hazardous concentrations encapsulate potential hazardous materials in a encapsulation chamber capable to contain any explosion or fire, preventing to spread outside the chamber causing secondary explosions Intrinsically Safe An intrinsically safe component is incapable of releasing sufficient electrical or thermal energy to cause ignition of a specific hazardous substance under normal or abnormal fault operating conditions.
Non Incendive Non incendive components are non-sparking and incapable of releasing sufficient electrical or thermal energy to cause ignition of a hazardous substances under normal operating conditions. Zone System - Protection Techniques High level protection concepts with the Zone system are indicated below.
This means that as older equipment in these locations is replaced, non-incendive sensors can replace the intrinsically safe. Along with explosion proof, intrinsic safety and non-incendive devices have their appropriate place in hazardous locations.
In the end, each has the same goal of safely deploying reliable electronic devices into explosive environments. Each has a different set of limitations and strengths. We can help you. Contact our Measurement Experts today to learn more about our liquid level sensors and pressure transducers certified for hazardous locations. What are the differences between an Intrinsically Safe device and a Non-Incendive one? Where can intrinsic safety sensors and non-incendive devices be used?
So why not just use intrinsically safe sensors and circuits? Hazardous Location. Username or Email Address. Remember Me.
