Measurement Technology for Potentially Explosive Areas

How to Design Intrinsically Safe Circuits

The intrinsic safety (Ex i) type of protection has established itself worldwide in the field of measurement and control technology in systems with potentially explosive areas. For one thing, it is much more cost-effective when it comes to construction when compared to other types of protection. For another, it allows for maintenance work and modifications during operation. Moreover, it is also possible to use simple electrical equipment without special approval.
