Monitor of Bursting Disc / Transmitter (Membrane)

The membrane signal transmitter for bursting discs (rupture disks) has been engineered specifically for the demanding operating conditions of the chemical and pharmaceutical industries. Manufactured from high-grade PEEK (polyether ether ketone) film and fitted with a conductive silver strip, the transmitter offers excellent thermal resistance and robust performance in harsh environments.

The silver strip conductor is fully wired, with cable length configurable to customer requirements. This enables safe and stable operation across a temperature range of -30°C to +200°C. When combined with an approved isolating switch amplifier, the membrane signal transmitter is also suitable for deployment in explosion-protected areas.

Available Versions

We supply membrane signal transmitters in two distinct formats to support different installation requirements:

• Strip Form: Clamped across the bursting disc for large nominal widths
• Disc Form: Covers the entire bursting disc surface for maximum contact and protection

In the event of a rupture, the bursting disc tears along with the transmitter membrane. This immediately breaks the closed circuit provided by the silver strip conductor, sending a direct fault signal to the internal process control system. The result: fast, reliable detection of overpressure events.

Technical Capabilities

• Operating temperature: –30°C to +200°C
• Material: High-grade PEEK film with silver conductor
• Explosion-protected use: Possible with approved isolating switch amplifier
• Custom wire length: Adaptable to system layout
• Installation height: Only 5 mm — suitable for retrofitting

Sizes & Integration Options

Depending on the application, membrane signal transmitters can be supplied in sizes from DN25 to DN500. Units may be delivered as:

• Complete assemblies paired with a compatible bursting disc (rupture disk)
• Standalone signal transmitters for installation upstream or downstream of a safety valve

With a low installation height of just 5 mm, the membrane signal transmitter can be easily retrofitted to existing plant infrastructure without major modification—ideal for upgrading monitoring capabilities on older systems.

Applications

These membrane-based transmitters are used wherever bursting disc activation must be detected quickly and reliably, including:

• Chemical processing plants
• Pharmaceutical production facilities
• Explosion-protected zones (with isolating amplifier)
• Systems requiring remote rupture monitoring

Engineered for reliability and extreme conditions, our membrane signal transmitters deliver precise, rapid fault indication, ensuring safe operation and full process oversight when used alongside bursting discs (rupture disks).
