Self-testing earthing clamp with visual indication

Bond-Rite CLAMP - Self-testing earthing clamp

The Bond-Rite® CLAMP patented exclusively by Newson Gale, is the only self-testing earthing clamp that provides operators with visual verification that potentially charged equipment is connected to a verified static earthing point. 

The Bond-Rite CLAMP contains a bright green LED which pulses continuously when it verifies that the resistance between the equipment to be earthed and the site’s verified earth grounding point (e.g. copper bus-bar) is 10 ohms or less.

The pulsing green LED provides process operators with a continuous visual reference point that enables them to monitor the earth status of equipment at risk of accumulating static electricity.

Once connected to equipment the Bond-Rite CLAMP continuously monitors the resistance of the circuit between the equipment and the verified earth point.

The Bond-Rite CLAMP is an ideal solution for applications and installations where interlocks with the process are not required or possible.

Typical Applications

> Filling and dispensing to/from metal containers, including drums, waste drums, mixing vessels.
> Earthing equipment used in mixing and blending operations.
