Universal B.D.I – Burst Disc Indicator

Continental Disc Corporation’s Burst Disc Indicator (B.D.I.) Alarm System is designed specifically for use with C.D.C. Rupture Discs. Upon disc rupture, the Burst Disc Indicator strip is severed, disrupting the flow of electric current through the strip. An attached alarm monitor can then transmit a warning and/or activate appropriate equipment.

The B.D.I.® Alarm Monitor has been developed as an optional alarm monitor system to notify operators or activate appropriate equipment of an overpressure or vacuum event for a specific B.D.I.® Alarm Strip. Control panels, annunciators, light panels or other signaling devices can be used to warn of a ruptured disc. The B.D.I.® Alarm System is versatile to adapt to a variety of warning devices. Pumps, valves and other systems may also be activated to respond to an overpressure of vacuum situation by the break of a specific B.D.I.® Alarm Strip.

Linking the B.D.I. Alarm Strip to the monitoring system is the B.D.I. Lead Wire Assembly. A two-pin bullet plug protects the terminals at the connecting point against moisture. It is abrasion resistant, flexible, and highly weather-resistant. Together this system will provide immediate notification of a burst disc to reduce downtime, increase efficiency and ensure the safety of your facility.
