Earth-Rite® Plus Static Ground Indication and Interlock System
Bulk loading or unloading railcars with liquids or powdered / loose solid materials can generate large electrostatic charges which poses
a significant risk in a potentially explosive atmosphere. Although the railcar is in contact with (earthed) tracks, many tank cars are
equipped with non-conductive bearings and wear pads located between the car itself and the wheel assemblies (trucks). This may lead
to an unsafe condition where an unearthed railcar accumulates a high static charge. Ground monitoring/verification systems may be
used to provide an interlock with the filling systems to prevent product transfer unless the railcar is properly bonded to earth. The Earth-
Rite® Plus provides indication of proper ground as well as relay contacts to control the transfer process. Earth-Rite® Plus can be used in
a wide range of industrial plant equipment including railcars, drums, containers and other conductive equipment.
•confirms safe, low-resistance static dissipation path (<10 ohms) from tanker, drum, etc. to designated ground point
•meets requirements of NFPA 77, API RP 2003 and CENELEC CLC/TR: 50404 recommended Best Practice on controlling static elec-
tricity in hazardous areas
•universal grounding clamp suits all common tankers, drums, conductive plant equipment
•ground connection junction box simplifies IS field wiring, system set-up and repairs in hazardous atmospheres
