Dwyer Instruments: Series MTL7706/7787, Zener Barrier

Intrinsically Safe Barriers for Hazardous Locations

The MTL7706/7787 is an intrinsically safe (IS) shunt-diode barrier that can be used to communicate with and provide isolations for certain Dwyer® transmitters approved for use in hazardous areas. These barriers limit the amount of energy allowed to pass into the hazardous area, which inhibit ignition in flammable atmospheres.

Series MTL7706/7787 Applications

  • Electrically isolates pressure and level transmitters from unregulated circuits for intrinsically safe applications
