Self-testing hazardous area static grounding clamp serves portable plant items

March 19, 2007

A grounding clamp specifically designed for hazardous area applications protects against static electricity build-up in mobile or portable equipment. The new clamp, the Bond-Rite™ clamp from Newson-Gale Inc. creates and continuously monitors a low-resistance connection to ground, providing visual verification through a flashing LED indicator.

Though mobile and portable items such as drums and other containers are difficult to bond effectively, the Bond-Rite clamp is at home in even the most demanding applications. Its tungsten carbide teeth and unique clamping action bite through insulating layers such as coated surfaces and built-up paint, resins, adhesives common in processing applications.

The intrinsically safe instrument’s body is made of 316L stainless steel and is powered by a long-life lithium battery, mounted internally for ease of installation. It is also dust and water tight and FM, CSA and ATEX approved. Application areas include Class I, Div. 1 and 2 Groups A,B,C,D; Class II, Div. 1 and 2, Groups E, F, G; Class III, T4.

Models for three standard configurations are offered: For ground-loop monitoring the clamp is equipped with a two-core self-retracting spiral cable, an in-line quick-connector junction box with ground-connection cables and a clamp stowage point. For clamp monitoring the clamp is equipped with a single-core self-retracting spiral cable and connection lug with an in-line quick-connector and clamp stowage point. And for either ground-loop or clamp monitoring the clamp is provided with an in-line quick connector for use with Cenelectrex cables or cable reels or the customers’ existing bonding cables.

The Bond-Rite clamp is just part of the Cenelectrex® range of static grounding and bonding equipment available from Newson Gale Inc., the Lakewood, NJ based specialists in static control for hazardous areas.
