STRIKO SVT AM Metallic Burst Indicator
The SVT AM is a fully metallic activation indicator for rupture discs. It is installed on the vent side and operates as an independent monitoring device, without affecting the relief cross-section calculation or the burst pressure of the disc.
Construction and Operation
The metallic membrane of the indicator is severed when the rupture disc opens. The change of circuit status is transmitted to PLC, DCS, SIS, or alarm panel, enabling process event logging and relief device activation monitoring.
Technical Specifications
- Type: Full Metal Burst Indicator SVT AM
- DN: 25 to 600
- Temperature: up to +600°C, with suitable sealing material such as Frenzelit isoplan® 750®
- Installation height: approx. 5 mm, suitable for retrofit applications
- Compatibility: metallic and graphite STRIKO discs, as well as discs from other manufacturers
- Installation: can be used with discs installed directly between flanges without a holder
Application Scope
SVT AM is selected for steam lines, hot gases, chemical plants, reactors, pressure vessels, and installations where temperature or chemical compatibility precludes polymeric membrane indicators. Sealing material selection must consider temperature, process media, flange pressure, and cleaning conditions.
ATEX / Intrinsic Safety
STRIKO indicators are classified as simple electrical equipment when connected to an intrinsically safe circuit. Assessment is based on EN 60079-11 and EN 60079-14, with appropriate barriers and installation zone documentation.
FAQ
Does it replace the rupture disc?
No. It only provides an activation signal.
Can it be retrofitted?
Yes, due to its low installation height (approx. 5 mm).
