Description
The BDI-FLX uses a sensor strip with a flexible potentiometer to instantly signal a rupture disc burst. 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.
Time-tested, ASME-accepted
Years of testing in our ASME-accepted flow test laboratory demonstrate the reliability of the BDI-FLX system. Years of field success have helped earn the trust of engineers and operators worldwide.
Maximum current: 50 milliamps
Maximum voltage: 24 VDC RMS
Operating temperature range: 40°F to +400°F (‑40°C to +204°C)
Minimum release pressure: See table, Minimum Pressure for Universal B.D.I.
Service: Gas, liquid
In fully liquid environments, the BDI-FLX sensor requires dynamic movement to send the signal. Slow disc reversal, such as with liquid thermal expansion, will not activate the sensor, nor will a cracked rupture disc.
DETAILS
The BDI-FLX allows direct interface with PLCs, distributed control systems, alarm monitors, or isolation barriers and can provide dry contacts for industrial controls.
The BDI-FLX system is built for durability, with:
A conductive element fully encapsulated in a corrosion-resistant polyimide film.
An advanced design to minimize the risk of damage to the sensor strip, even when bolts have been tightened beyond the recommended torque.
An alignment ring to support the sensor cable and minimize cable strain.
Updated output cable connectors per the IP67-rated M12 connector according to IEC 61076-2-101.
Please note that the BDI-FLX sensor 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 there will not be full liquid flow at the set pressure or a gas head present during disc rupture, contact LaMOT for an evaluation. The BDI-FLX system is designed for use with LaMOT standard and composite rupture discs paired with B.D.I.® alarm strips.
