Burst Disc Indicator Alarm System

Reduce downtime, increase efficiency and ensure the safety of your facility with the BDI (Burst Disc Indicator) Alarm System. When an overpressure or vacuum condition causes a disc to rupture, the BDI immediately sends a signal to the control room to alert the system operator.

The heart of the Burst Disc Indicator Alarm System is the BDI Alarm Strip. When a disc ruptures, it severs the electrically charged strip, opening the circuit and signaling the control room.

We’ve developed an optional alarm monitor system to notify operators 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.
