Burst Discs
Sanivent RBH Bursting Discs
The RBH reverse buckling disc has been adapted for use in the well-proven hygienic clamp fittings, widely adopted by the pharmaceutical, biotechnology, brewing, dairy and similar industries; anywhere that high levels of hygiene are essential.
The discs are provided with a profiled seal that conforms exactly to the pipe ferrule flanges ensuring that there are no crevices for product deposits. The non-fragmenting disc design is such that there will be minimal restriction to vent flow in the event of the disc rupturing due to an excessive pressure.

Burst Disc Indicator
This design of reverse buckling disc is also compatable with the Marston Burst Disc Indicator. The polymide (Kapton) membrane supports the conductive loop across the vent-side of the bursting disc.
This loop is connected to the customer's alarm circuitry by a flexible trailing lead that passes through the ferrule clamp. When the disc bursts the loop is broken, interrupting the electrical circuit and immediately providing a signal.
When coupled through a suitable switch barrier that limits the current to <100mA the BDI device conforms to EEx ia IIC T6 (Tamb=75C) for hazardous area duties.
