Earth-Rite RTR™ Static Ground Indicating & Interlock Systems

Check up to five results to perform an action.


For many applications handling flammable or combustible material transfers with conductive items being involved, the Earth-Rite ground verification system confirms the connection to a proper ground and monitors the static path according to International static control requirements, while providing red/green LED light’s for operator awareness and a voltage free switch contact which may be interlocked with pumps, valves, alarms, etc.

The Earth-Rite RTR™ Tri-Mode is a unique system specifically designed for road tanker trucks. In addition to a ground continuity check, the system carries out a “tanker verification” check, confirming that the dual circuit ground clamp has been applied to the tanker truck and not any other conductive object. Keeping with the Tri-Mode design, a third operational check is conducted verifying that the system is properly connected to a proper dissipative ground/earth path. Included with the system is a voltage free switch contact which may be interlocked to a designated control device, which will only operate went the three verification checks are properly satisfied. The resistance set-point to proper ground is < 10 Ohms meeting current NFPA77 standards. Certified: FM Approved for Class I & II, Division I & 2, Groups A, B, C, D, E, F, & G.
