Burst Disc Indicators

The BDI-FLX Burst Disc Sensor System provides instantaneous notification of a burst rupture disc. When combined with an alarm monitor, this system protects lives, equipment and the environment. Designed for use with ASME and DIN flanges or sanitary applications, the BDI-FLX employs a sensor strip with a flexible potentiometer (an electrical component that varies resistance in response to deflection) to signal a burst disc.

A critical component of a complete Burst Disc Indicator (BDI) Alarm System, the MTB-700 Alarm Monitor links to as many as four rupture discs to alert your nearby control room of ruptured discs. Upon disc rupture, the MTB-700’s intrinsically safe galvanically isolated barriers activate signals or output relays to warn operators and actuate pumps, valves or other equipment connected to the 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.
