The Earth-Rite® OMEGA II is a compact panel mounted static earthing relay system that monitors a range of pre-set resistance values, based on the application and installation requirements of specific processes.
The OMEGA II monitors the resistance of the static earthing of processes where static charge accumulation on the equipment could result in an incendive spark discharge in EX/HAZLOC areas.
It is specified primarily for applications where an alternative means of earth status indication is required, 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 unit can be located in electrical panels mounted in non-hazardous areas or inside certified flameproof enclosures 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 thereby eliminating the source of charge generation.
Ground Resistance Monitoring Set Points
The OMEGA II is designed specifically for monitoring the static earthing of process equipment and has 4 resistance set points depending on the installation and operating characteristics of the application. It can also be installed to monitor the resistance of bonding circuits and lightning protection earthing points.

Benefits
Operating Resistance Levels 0 ohms to 2 ohms (to monitor low resistance bonding paths. 0 ohms to 4 ohms. 0 ohms to 10 ohms (recommended values of resistance in IEC 60079-32 & NFPA 77). 0 ohms to 600 ohms (to monitor the grounding of rotating machinery). Two Output Contacts Located in the Omega II control unit, two dry output contacts can be interlocked with pumps or other control devices to prevent transfer operations should a reliable static Ground Loop fail to be established or maintained for the duration of the transfer process.
