Earth-Rite RTR is the most advanced Tanker Truck Grounding System for protecting personnel and plant assets from static discharge hazards during loading & offloading operations. Tri-mode sensing insures that product transfer can only commence and be sustained when three key provisions are met.

Mode 1 • Tanker Truck Personality Recognition

Confirms RTR clamp is correctly connected to the tanker itself—not falsely connected to other conductive metal objects such as the loading gantry or other parts of the truck not bonded to the container.

Mode 2 • Static Ground Verification

Confirms RTR clamp is connected to a verifiable static dissipative grounding point.

Mode 3 • Continuous Ground Loop Monitoring

Confirms clamp connection and ground connection is good throughout the transfer process by insuring loop resistance does not exceed 10Ω.

Operator friendly interface provides GO / NOGO indication when the tanker is correctly grounded. Bright pulsating green LEDs are activated during the MODE 3 continuous ground loop monitoring stage.
Control / Interlock capability includes two relay contacts for pump, valve, and PLC control integration, plus connection to devices such as strobe lights and horns confirming transfer is under way.

Compliance with NFPA77 and CENELEC CLC/TR: 50404 to insure less than 10Ω ground loop resistance.

Hazardous location approvals includes CSA for the U.S. and Canada, compliance with the ATEX Directive for use in the European Community, and certification to IECEx standards for other international users.

Earth-Rite MGV (Mobile Ground Verification)Truck Mounted Grounding System

  • Perfect for installation on vacuum trucks and tankers
  • Provides confirmation of acceptable electrostatic ground connection
  • Interlocks with pump control system, strobe lights, etc.
  • Continuously monitors low resistance static path during material transfer
  • Satisfies API RP 2219
  • Red/green LED status indication
  • Intrinsically safe sensing circuit
  • Class I II III, Division 2, Groups A-G
  • Class I, Division 1 optional housing available
  • CSA U.S. and Canadian approvals
  • ATEX, IECEx certification
  • Powered from 12 or 24 VDC vehicle power
  • Easy to install & operate, operator friendly
  • Stainless steel clamp with tungsten carbide tips

Earth-Rite MGV is the most advanced mobile truck grounding system for protecting personnel and plant assets from static discharge hazards during material transfers. The MGV system performs two operational checks to insure the vehicle can dissipate static charges during the loading or unloading process.

Check 1 • Static Ground Verification

The MGV system insures the connection resistance of the designated grounding point, or expedient ground of opportunity, is low enough to safely dissipate static charges from the truck.

Check 2 • Continuous Ground Loop Monitoring

When the static ground verification process has been confirmed, the MGV system continuously monitors the connection resistance of the the truck to the designated ground point for the duration of the transfer process. The connection resistance must be maintained at 10 ohms or less. Note: ground rod shown in illustration at right is not included.Easy and quick operation removes the need for the vehicle operator to make assumptions about the quality of designated grounding points, or responsibility for making manual resistance measurements.

Datasheet 

Bond-Rite® EZ Grounding Cable

  • Portable double-ended bonding cable
  • Simple to use
  • Intrinsically safe: CSA, ATEX & IECEx
  • Pulsing green LED indication
  • Battery operated
  • Water & dust tight
  • Rugged stainless steel clamps with tungsten carbide teeth
  • Unique clamping action
  • Hytrel spiral cable with quick disconnects for clamps

The Bond-Rite EZ provides a portable self-testing bonding solution for those times when liquid or powder transfers need to take place and no permanent grounding monitor is available. The uniqueBond-Rite CLAMP is combined with a Hytrel protected spiral cord and secondary clamp to create a reliable bond between mobile equipment and a metal structural ground. Tungsten carbide tips bite through paint, rust, and other surface deposits.

The intrinsically safe monitoring circuit electronics and battery are contained within the primary clamp. Quick disconnects allows the clamp to be easily removed for battery replacement in a non-classified area. Note: ground rod shown in illustration above is not included.
