Earth-Rite Multipoint monitoring system

For plants that include several potentially isolated conductive parts, the Earth-Rite Multipoint monitoring system provides protection against dangerous static-electricity buildup in various components. Typical applications include powder handling equipment, filling/discharging devices, fluidized-bed dryers, pipelines, conveyors and ducting, especially where one or more parts of the assembly must be disconnected periodically. The ATEX-approved system can provide individual status indications, or it can be linked to a lock-out control system that prevents operation until proper grounding has been achieved. For applications with more than eight points, two or more systems may be combined, and a versatile range of connections and cables are available to provide the connection point onto the equipment to be monitored. The intrinsically safe system ensures that all elements are connected together and safely grounded, providing up to eight interconnected channels from a single intrinsically safe supply. An important design criterion is that the sum of all the circulating currents does not compromise the intrinsic safety of the monitoring system
