Grounding Monitoring Device Series 8485

Grounding Monitoring Device Series 8485

Series 8485

  • Controlled electrostatic grounding of road tankers and rail cars during loading
  • Continuous monitoring of correct grounding
  • The object recognition prevents potential operator errors (with road tankers)
  • Water jet protected aluminium enclosure IP65
  • Two potential-free change-over contacts per channel for signalling
  • Insulated point of suspension for clamps
  • Ambient temperature - 55 ... + 60 °C

The ground monitoring device ensures the electrostatic grounding of road tankers and rail cars while loading flammable liquids and powder. The device provides a conductive connection to the ground and monitors in parallel the quality of the electrostatic grounding. This guarantees that the electrostatic charge remains at a safe level and that no explosion hazard is generated by uncontrolled energy discharge.

The following recommendation requires grounding during loading and recommends interrupting loading in case of incorrect grounding:

  • CENELEC LC/TR 50404 recommendation for avoiding ignition hazards due to electrostatic charges.
  • TRGS 727 rules for avoiding ignition hazards as a result of electrostatic charges
