BURSTING DISC ACCESSORIES - webadmin1.net

Rupture IndicatorType RI – RI2 – BC2 – BC-HDescriptionThe Fike Indicator will give instant warning that a bursting disc hasruptured, and that products may be venting into the atmosphere, orthat product may be lost or contaminated if the bursting disc is notimmediately replaced. It can interlock with control equipment inorder to stop or alter the process. If the bursting disc or safety valverelieves into a common header the signal obtained from the RI willindicate the location of the problem.RI / RI2The RI consists of an insulated electrically conductive strip attachedto a stainless steel baffle, which is supported by a stainless steelring. The RI is equipped with a built-in self-resetting fuse forprotection against unacceptably high currents.Compared to the standard RI, the RI2 includes additional series andend of line resistors to provide a full wiring supervision. The RI2burst indicator offers a high Safety Integrity Level: SIL 2 according toIEC61508. Both indicators are supplied with 3m of electrical wire.BC2The BC2 consists of an insulated conductive strip attached to aTeflon film. As a standard the BC2 is supplied with 18” (0,46m) ofelectrical wire and a 3-pin quick connector plug.BC-HThe BC-H is specifically designed for use with the SR-H, AXIUSSC or SHX hygienic service bursting disc. As a standard the BC-His supplied with 18” (0,46m) of electrical wire and a 3-pin quickconnector plug.BURSTING DISC ACCESSORIESFeatures and Benefits• Rigid flange construction• Corrosion resistant• Easy replacement upon disc ruptures• Compatibility with standard design burstingdiscs and safety relief valves• High mechanical rigidity• Simple “plug & play” design• Integral self-resetting electrical fuse (RI, RI2)• Complete wiring supervision (RI2 only)• IEC61508-SIL2 approved (RI2 only)BC2BurstingDiscBC2BurstingDiscNote:The RI, RI2 and BC2 / BC-H TM are designed for use withintrinsically safe electrical alarm or control equipment, whichis initiated by an open-circuit signal.MountingThe Fike burst indicators can be mounted on the vent side of a bursting disc assembly or safety relief valve. Forlarge bursting discs (> DN150/6”) a spacer ring may be required to prevent contact between the protruding domeof the bursting disc and the burst indicator.8.1800.00.7
