Zener Barriers

Gems Sensors Zener Barriers are passive, energy-limiting devices that provide intrinsically safe DC outputs for sensors such as level and flow switches, transducers, and transmitters. By limiting energy at the switch terminals far below ignition levels, these barriers eliminate the need for costly explosion-proof enclosures, making hazardous location compliance simple and economical.
