BDI-FLX Burst Disc Sensor System
BDI-FLX Burst Disc Sensor System
A system of sensors and wires that relays a burst disc notification to the MTB-700 alarm monitor (or other monitoring system).
BDI-FLX employs a sensor strip with a flexible potentiometer to instantaneously signal a burst disc. It is designed for use with ASME and DIN flanges or sanitary applications. When combined with an alarm monitor, this system protects lives, equipment and the environment.
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.
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.
