How the BDI-FLX Burst Disc Sensor System works

The BDI-FLX Burst Disc Sensor System maintains a continuous signal with an alarm monitor. If the disc bursts, the BDI-FLX Sensor System notifies the alarm monitor by opening the electrical circuit.

Continental Disc Alarm Monitors contain replaceable modules with individual channel relays. Each channel relay connects to one BDI-FLX Sensor System. As the rupture disc bursts and the BDI-FLX Sensor System indicates the event, a specific relay is actuated, sending a signal to the control panel.

  • The BDI-FLX Sensor System can adapt to a variety of warning devices. Control panels, annunciators, light panels or other signaling devices can be used to warn of a ruptured disc
  • Individual relay circuitry allows users to monitor several BDI-FLX Sensor Systems simultaneously
  • The BDI-FLX Sensor System can also notify of overpressure situations when paired with pumps, valves and other systems
  • If the BDI-FLX Sensor System loses power, it defaults to an open circuit

The BDI-FLX Burst Disc Sensor System is available for gas or liquid applications

For full liquid applications, the BDI-FLX Sensor System requires sudden movement to signal. Slow reversal of the rupture disc, such as with liquid thermal expansion, will not cause the BDI-FLX Sensor System to indicate. A small crack in a rupture disc score will not cause the BDI-FLX Sensor System to indicate.

Note that the BDI-FLX Sensor System is designed to indicate within a few milliseconds, so full reversal and full opening of the rupture disc must occur within a few milliseconds. If full liquid flow at set pressure or a gas head will not be present during rupture of disc, contact us for an evaluation.
