AVAILABLE FOR INDUSTRIAL AND SANITARY APPLICATIONS The BDI-FLX™ Burst Disc Sensor System utilizes an electronic instrument which provides instantaneous notification of the bursting of a rupture disc using versatile interface cable options. When combined with an alarm monitor, this system provides protection for lives, equipment and the environment. Designed for use with ASME and DIN flanges 1”-12” (25mm-300mm) or sanitary applications 1”-4” (25mm-100mm), the BDI-FLX Burst Disc Sensor System utilizes a sensor strip with a flexible potentiometer (electrical component that varies resistance in response to deflection) to signal a rupture disc has burst. BENEFITS The BDI-FLX Burst Disc Sensor System provides many benefits, which include: Allows direct interface to PLC’s, DCS (Distributed Control Systems), alarm monitors or isolating barriers and can provide dry contacts for industrial controls Figure 5 Improved durability: • The conductive element is fully encapsulated in corrosive resistant polyimide film • The advanced technologies of the sensor strip minimize the risk of damage due to excessive stress beyond recommended bolting load • The alignment ring provides a rigid support for the sensor cable, minimizing cable strain Modernized output cable connectors in accordance with IEC 61076-2101. IP67 rated M12 connector. BDI-FLX The BDI-FLX sensor is installed at the downstream side of a rupture disc, bolted between the rupture disc holder and flange or sanitary ferrule as shown: FIGURE 1 OUTLET COMPANION FLANGE BDI-FLX SENSOR LABEL BDI-FLX SENSOR RUPTURE DISC & HOLDER ASSEMBLY INTEGRAL BDI-FLX INSTALLATION INLET GASKET INLET COMPANION FLANGE FLOW BDI-FLX™ BURST DISC SENSOR SYSTEM INSTALLATION OF THE BDI-FLX BURST DISC SENSOR SYSTEM PERFO RMANC E

CONTINENTAL DISC ALARM MONITORS BDI-FLX SENSOR SYSTEM, INCLUDING ALARM MONITOR A continuous signal flows between the BDI-FLX Burst Disc Sensor System and the Alarm Monitor under normal conditions. Once the rupture disc bursts, the BDI-FLX Sensor System indicates the event, opening the electrical circuit. NOTE: If the BDI-FLX Burst Disc Sensor System loses power, it defaults to an open 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...
