Intrinsic Safety Barriers

Overview

Passive and active zener-type intrinsic safety barriers as well as active galvanic isolators allow sensors to be installed in Zone 0, Zone 1, or Div 1 hazardous areas without the use of explosion-proof wiring practices and housings. For the correct barrier type for a specific sensor, consult the TMM and UMM datasheets. These barriers may be purchased directly from the manufacturer, or can be supplied by Brüel & Kjær Vibro upon request.
