Static Grounding for Type C FIBC Bags
The Earth-Rite® FIBC system monitors the resistance of Type C FIBC bags ensuring the static dissipative elements of the bag are capable of conducting electrostatic charges through the FIBC in compliance with IEC 61340-4-4 “Standard test methods for specific applications – Electrostatic classification of flexible intermediate bulk containers (FIBC)” and NFPA 77 “Recommended Practice on Static Electricity”.
To compensate for normal wear and tear on Type C bags it is important to ensure the bag maintains its ability to dissipate electrostatic charges. It is equally important to ensure earthing connection between the bag and plant earth grounding point is functioning correctly.
During the bag filling / emptying process the Earth-Rite® FIBC system continuously monitors the resistance of the Type C bag. If the resistance of the bag rises above the recommended level of 1 x 107 ohms (10 meg-ohm) this dangerous situation averted through system mounted indicators that inform the operator the process must be halted. The system’s volt-free contacts can be used to automatically shut down the operation or activate some additional attention grabbing devices.
Newson Gale can also provide the Earth-Rite FIBC configured to validate and monitor Type C bags that are designed to operate with an upper resistance level of 1 x 108 ohms (100 meg-ohm).

Benefits
Resistance monitoring system
combined with machine interlocking output contacts (x2), ensures operators correctly clamp and ground the bag before filling or emptying can commence.
Continuously monitors
the resistance of the bag while the process is underway, ensuring static charges have a safe static dissipative path to the plant earth ground.
Red and Green Pulsing LED indicators
tell operators whether or not a good ground connection is made.
