CDC BDI-FLX Burst Disc Sensor System by prdtechgroup.com

BDI-FLX™

BURST DISC SENSOR SYSTEM

BDI-FLX™

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, the environment and process media. It can be used with customers monitoring systems or with an alarm monitor provided by Continental Disc Corporation.

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.

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.

Monitor Model

* The BDI-FLX 4W-NIS model can work with any of our monitor models if separate input power is provided. However, the

is NOT for intrinsically safe applications and is not recommended for use in hazardous locations.

ALARM MONITORS

The CDC Alarm Monitors have been developed as an optional alarm monitor system to notify operators or activate appropriate equipment of an overpressure or vacuum event. Control panels, annunciators, light panels or other signaling devices can be used to warn of a ruptured disc. The CDC Alarm Monitor is versatile to adapt to a variety of warning devices. Pumps, valves and other systems may also be activated to respond to an overpressure or vacuum situation by the indication of the BDI-FLX Burst Disc Sensor System.

Together, the BDI-FLX Burst Disc Sensor System with a CDC Alarm Monitor will provide immediate notification of a burst disc to reduce downtime, increase efficiency and ensure the safety of your facility.
