Intrinsically Safe Zener Barriers
Available from Gems Sensors & Controls
Zener Barriers: These passive, energy-limiting devices, provide intrinsically safe DC outputs for a variety of sensors such as level and flow switches...level indication 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.
