Earth-Rite PLUS grounding indicator system

The Earth-Rite PLUS grounding indicator system provides a fail-safe assurance of a low-resistance path to ground for static electricity dissipation during the transfer of flammable liquids or powders to or from tanker trucks, railcars, drums, containers, or virtually any other conductive equipment. Its features now include an optional heavy-duty stainless-steel ground clamp, a retractable coiled grounding and monitoring cable, and a quick-connect design for fast field replacement of the clamp or cable. The wide-jaw heavy-duty stainless-steel clamp provides a universal method of connecting to all common mobile tanks and vessels. Stainless steel is used in the body, spring and fasteners of the clamp, while the sharp contact points are made of tough tungsten carbide. The clamp’s contact arrangement ensures contact with flat or curved surfaces, and a special grip profile makes it suitable for direct connection with grounding posts, rods and pins. It has been tested and approved as a static grounding device by FM for its electrical continuity, positive spring pressure, mechanical strength, and resistance to high-frequency vibration. The Cen-Stat grounding and monitoring cable is color-coded blue for intrinsic safety, and has a chemical- and abrasion-resistant outer coating that also has antistatic properties. The cable’s standard extended working length is 32 ft, with optional lengths of 16 or 48 ft. A 50-ft self-rewind static-ground cable reel with ultra-low-resistance slip-ring contacts is also available. The system meets U.S., Canadian and European hazardous area standards and directives, including the American NFPA 77 and the European CLC/TR 50404.
