SB-S Signalling Discs

Like the SK signaling device, this signaling system uses the principle of closed circuit technology. The signaling membrane is mounted directly between the flanges on the venting side of the rupture disc. When the rupture disc breaks, the pressure of the discharging process medium destroys the SB-S membrane and the intrinsically safe circuit is broken. This sends an error message to the process control system. Also available without a relief bore for monitoring leakages.
