The Earth-Rite® FIBC system validates and monitors the resistance of Type C FIBC bags ensuring that the conductive elements of the bag are capable of dissipating electrostatic charges 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”.
The Earth-Rite FIBC system can be installed and setup to ensure that operators ground the bag before filling or emptying operations are started. During the bag filling / emptying process the Earth-Rite FIBC system continuously monitors the resistance of the bag so that if it rises above the recommended level of ohms (10 meg-ohm) this dangerous situation can be indicated to operators and the process halted, either manually or via the system’s pair of NO/NC volt free contacts. This feature ensures the generation and accumulation of static charges on the bag is stopped eliminating the risk of an electrostatic spark discharge.
Note: Several configurations available! Please call for more information.
Features
- Attention Grabbing LEDs: Three green LEDs continuously pulse informing operators that the FIBC bag to be protected from static discharges is correctly grounded - When the system is not in use, or when it detects the resistance in the static dissipative loop is higher than 1 x 10⁷ or 1 x 10⁸ Ohms a red LED illuminates the indicator panel located in the static dissipative GRP indicator station
- Continuous Ground Loop Monitoring: Monitors the resistance of the static dissipative loop through the FIBC bag back to the Earth-Rite FIBC via the plant earth grounding point - If the system detects that resistance in the loop is higher than 1 x 10⁷ohms, it engages a pair of output contacts
- Two Volt Free Output Contacts: The primary contact can interlock with electro-mechanical devices or PLC systems to shutdown the flow of product - The secondary contact can interface with attention grabbing audible alarms or strobe lights to provide an extra degree of safety over the hazard
- Easy Installation: Simple to mount enclosures complemented by straightforward cabling and PCB system wiring - Flexible hazardous area enclosure location options with separate IS monitoring / indicator and Power supply PCBs. Power supply PCB can run off both 240 V and 110 V mains / line supply and 24 V / 12 V DC voltage supply
