The Role and Purpose of a Burst Disc Indicator

A burst disc indicator is a monitoring system paired with rupture discs, the pressure safety devices used to regulate the high pressure or vacuum condition inside a vessel or a closed system. The burst disc indicator triggers an alarm whenever the rupture disc bursts. Burst disc indicators paired with rupture discs are used in a wide range of high-risk industrial or high-pressure applications where monitoring the operation of rupture discs is hard.

How does a burst disc indicator work?

The burst disc indicator also known as the rupture detection sensor sends a signal alert whenever a disc ruptures. The alarm strip inside the rupture disc indicator opens the circuit and generates the electrical signal. An alarm is triggered indicating to the system operator that there is a condition of high pressure or vacuum that might lead to bursting of the rupture disc.

The operating condition of rupture discs can be examined with the help of a burst disc indicator to decide whether or not to replace the rupture disc. The universal burst disc indicator is designed in such a way that it can be installed between the bolted flanges.

Alarm strip, the heart of the burst disc indicator

The burst disc indicator system consists of an alarm strip which is the heart of the burst disc indicator. The alarm strip made of copper conductors is designed to send an alert opening the electrical circuit whenever the rupture disc bursts due to high pressure. 

What are the features of burst disc indicators?

Understanding the features helps to choose compatible burst disc indicators. Here are the features of burst disc indicators used with various rupture disc models.

·        Sends electrical signal to trigger the alert as soon as the rupture disc bursts.

·       The device provides both visual and electrical indication of rupture disc failure.

·       The burst disc indicator is compatible with high-temperature conditions.

·        Both forward-acting and reverse-acting rupture discs can be paired with a burst disc indicator.

·       Burst disc indicators are resistant to corrosion.

·       The device system can be replaced quickly whenever the rupture disc bursts.

·       Increases efficiency of rupture disc operations.

·       Burst disc indicator is resistant to chemicals.

·       The burst disc indicators can be replaced easily.

·       Helps to identify pressure-related issues and provides an instantaneous alert to the system operator.

·       Burst system Indicator adapts quickly to a wide range of safety risks caused due to high-pressure.

·        Burst discs are certified for use in potentially hazardous or explosive atmospheres.

·       The burst disc indicator system will not affect the performance of the rupture disc.

·       The device is carefully designed to operate under highly explosive atmospheres.

·       Burst disc indicators are widely used with the continental type of rupture discs.

The wide range of applications in which burst disc indicators are used

Burst disc indicators are used in a wide range of industrial applications such as

• Storage tanks.

• Processing vessels.

•  Distillation equipment.

• Chemical reactors.

•  Relief valves.

• High-risk applications such as petroleum refining.

The alarm and monitoring system used with pressure safety devices such as rupture discs ensures the safe operation of the devices by initiating an early alert to the system operator whenever the rupture discs burst due to high pressure. A compatible burst disc indicator can be used with the diverse models of rupture discs. The system combined with an alarm monitor plays a significant role in monitoring the rupture disc operations and providing an early alert to the system operator in the event of high-pressure conditions causing threats to the lives of people.
