Intrinsically Safe Barriers

Zener Barrier Series Image
  • Lower-power switching
  • Completely encapsulated construction
  • Modular housings for easier installation
These passive, energy-limiting devices provide intrinsically safe DC outputs for a variety of sensors such as level and flow switches...level indicating transducers and transmitters…and many others. The maximum energy possible at the switch terminals of the SAFE-PAK and Zener Barriers is far below the explosive point of the most volatile surrounding gas conditions. The type of non-voltage producing switch or sensor best suited for the application can be utilized, since the entire switching circuit is rendered intrinsically safe by the SAFE-PAK or Zener Barrier. As the switching circuit is low voltage, there is no shock hazard to operating or maintenance personnel.
  • Solid-state reliability
  • Consistent performance
