Newson Gale Earth-Rite® PLUS

The Earth-Rite^® II PLUS is a flexible active ground monitoring system that enables the static grounding of a wide range of metal ‘objects’ approved for use in all classified hazardous locations. Such objects include, but are not limited to:

Metal totes and drums
Railcars
Metal frames of EX IBCs
Pump metering skids

In line with recommended practice, it is advisable that plant operators follow a simple protocol of “Clamp On First, Clamp Off Last” (CoF/CoL). This should, wherever possible, be incorporated into the process operators’ SOP.

To help minimize interaction with complex system interfaces, the process operator does not need to interact with any settings or interpret any readings on the Earth-Rite® II PLUS system. By simply attaching the grounding clamp of the Earth-Rite® II PLUS to the object requiring static grounding, the system will automatically determine if the connection resistance to the object is 10 ohms or less. It achieves this by passing an intrinsically safe signal via the clamp teeth into the base metal of the object. If a connection resistance of 10 ohms or less is achieved, the signal returns to the Earth-Rite® II PLUS where the circuit electronics register a permissive condition.
