STRIKO SVT 02 Rupture Disc Burst Indicator
The SVT 02 is an electrical activation indicator for rupture discs. It is installed on the vent side, downstream of the disc or safety valve, and provides a signal when the relief device opens. The indicator is independent of the disc and can be used with STRIKO metallic or graphite rupture discs, as well as discs from other manufacturers.
Construction and Operation
The sensor consists of a PEEK membrane with a conductive silver track. Under normal conditions, the circuit is closed. Upon disc rupture, the membrane breaks and the circuit opens, sending a signal to PLC, DCS, alarm panel, or safety circuit.

Installation
SVT 02 is supplied ready for installation with seals and connection cable. Compatible with DIN, ANSI, and JIS flanges, as well as direct disc-to-flange mounting without holder. Sealing material selection must consider temperature, chemical compatibility, and allowable flange compression.
ATEX and Intrinsic Safety
STRIKO indicators are classified as simple electrical equipment when connected to an intrinsically safe circuit. Installation must comply with EN 60079-11 and EN 60079-14, with appropriate barriers and zone documentation.
Typical Applications
Chemical lines, pressure vessels, scrubbers, reactors, gas lines, steam installations, and systems requiring confirmation of disc opening. For micro-leakage detection prior to full rupture, refer to SVT 05 leakage sensor.
