Series TR-7 Safe-T-Ground

Brand: Dwyer Instruments, LLC

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.
