Hazardous Area Static Grounding System

September 13, 2011
The newly upgraded, intrinsically safe Earth-Rite TELLUS® II from Newson Gale Inc. offers effective, constantly verified static ground monitoring for drums, IBCs and other mobile or portable equipment during hazardous area operations. It is suitable for use in the handling, transporting or mixing of combustible products, whether they be powders or liquids, and in any industrial flammable or combustible atmosphere. When in use the TELLUS II provides the operator with a bright green flashing LED to confirm a positive connection to ground, and also provides a pair of output contacts for interlock with pumps, valves or other control or alarm devices. Operating in real time, the system confirms that a positive connection to ground remains intact for the duration of the operation. As long as the resistance of the connection to a designated ground exists and remains below the generally accepted international safety standard of 10 ohms, a bright green pulsing LED display inside the hazardous area assures the operator of that there is no buildup of dangerous static electricity.
