Model TR-7 SAFE-T-GROUND

Explosion-proof, Intrinsically Safe, Ground Continuity Control

Model TR-7 Safe-T-Ground provides continuous monitoring of a truck’s ground connection throughout loading operations. Static electricity is often brought in by tank trucks entering the loading area. The Safe-T-Ground Model TR-7 instantly stops loading operations if a tank truck loses its ground.
To safeguard loading operations, the Safe-T-Ground circuit can be wired into your pump control – and to an audible alarm or signal light.
