Earth-Rite® OMEGA

DIN-rail module for static ground loop monitoring

The Earth-Rite OMEGA II is a compact panel mounted static grounding module that can monitor a range of resistance values, based on the earthing application and installation requirements of specific processes.

The OMEGA II monitors the resistance of the static earthing circuit for processes where a risk of static charge accumulation on the equipment could result in an incendive electrostatic spark within locations that have potentially flammable atmospheres present.

It is specified primarily for applications where an alternative means of earth status indication is provided, e.g. via panel mounted indicators or remote indicator stations, as opposed to more regular earthing solutions in the Earth-Rite range.

The DIN rail mountable module can be located in an electrical panel mounted in a non-hazardous area or inside an Ex(d) certified enclosure located inside the hazardous area.

Two volt free changeover contacts can be used to switch power to additional earth status indicators or interlock with the process to shutdown product transfer when the OMEGA II detects an open circuit on the path to earth.

  • 0 - 2 Ohm (to monitor low resistance bonding paths)
  • 0 - 4 Ohm
  • 0 - 10 Ohm (recommended values of resistance in IEC60079-32 & NFPA77)
  • 0 - 600 Ohm (to monitor the earthing of rotating machinery)
