LED indicators informing the operator if 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 10^8 ohms, a red LED illuminates the indicator panel located in the SDP indicator station,
the system can be setup to physically prevent FIBC filling/emptying operations (interlock) if the bag is not grounded,
if the resistance of the bag rises above the recommended level of 1 x 10^8 ohms the process can be halted.
monitoring system: Ex II 1 GD EEx [ia] IIC T4,
power supply / interface: Ex II 1 GD EEx [ia] IIC T4, Ex II 1 GD Eex d IIB T5,
Power supply: 230V or 110V ± 10%, 50 Hz,
Pre-set electrical resistance: 1 x 10^8 Ω (100 megohms),
System components: monitoring unit with earth status indicator LEDs, holder for clamp storage, power supply unit with interlock for filling/emptying operations, special monitoring clamp complete with hytrel covered spiral cable.
control unit for an explosion protection system (HRD containers, pressure and infra-red detectors),
this multi-zone control unit performs the following control and diagnostic functions: system monitoring, distribution of stored energy for actuation of explosion-protection equipment and on-line verification of the status of an explosion suppression system,
its modular design allows selective system activation (e.g. system activation for a single piece of equipment in which an explosion occured).
the Earth-Rite OMEGA system enables engineers, contractors and OEMs to incorporate dedicated static earth monitoring as part of larger plant instrumentation and control systems,
the Earth-Rite Omega module is designed for rail mounting (35 mm, DIN standard) into control panels. The system is capable of checking resistance between two points and providing relay output switching at a user-defined set point,
typical applications include temporary ground condition monitoring of all mobile conductive plant items and permanent continuity monitoring of fixed plant items in all flammable atmosphere zones, as well as monitoring simple devices such as float switches in hazardous areas.
for bonding/earthing of portable/mobile plant equipment (drums, containers, FIBCs, tankers, etc.),
plant items usually have a built-up of additional insulating layers, such as paints, resins, adhesives and other substances inherent to the processing environment, which creates a challenge to standard earthing clamps and may result in the clamp appearing to be physically attached, but not actually performing its intended function (safe static dissipation),
the Bond-Rite clamps are in compliance with stringent safety standards and are suitable for use within ATEX zones.
