Zener & Galvanic Barriers
- Zener and galvanic barriers are two types of electrical protection devices used in hazardous or explosive environments to prevent the ignition of flammable gases, vapours, or dust. These barriers are commonly employed in industrial settings such as oil refineries, chemical plants, and mining operations.
What are Zener Barriers?
A Zener barrier is an intrinsically safe device used to...
