The Fike Burst Indicator will give instant warning that a bursting disc has ruptured and that products may be venting into the atmosphere, or that product may be lost or contaminated if the bursting disc is not immediately replaced. It can interlock with control equipment in order to stop or alter the process. If the bursting disc or safety valve relieves into a common header the signal obtained from the RI will indicate thelocation of the problem.
RI / RI2
The RI consists of an insulated electrically conductive strip attached to a stainless steel baffle, which is supported by a stainless steel ring. The RI is equipped with a built-in self-resetting fuse for protection against unacceptably high currents.
Compared to the standard RI, the RI2 includes additional series and end of line resistors to provide full wiring supervision. The RI2 burst indicator offers a high Safety Integrity Level: SIL 2 according to
IEC61508. Both indicators are supplied with 3m of electrical wire.
