Leakage Sensor Typ SVT 05
The STRIKO leakage alarm SVT 05 represents the meaningful further development and indispensable supplement of the proven STRIKO alarm SVT 02. It is furnished with a product side, closed PTFE film that will curve also with a slow press increase which will destroy the conductor circuit. The response pressure is only slightly above the values of the alarm SVT02.
Advantages in the application
- Quick recognition of malfunctions, also for leaking bursting discs (e.g. through pitting corrosion or hairline cracks) or safety valves
- Highest corrosion resistance through PTFE film closed on the product side
- Ready-to-install delivery
- All materials used are asbestos-free
- Suitable for all metal and graphite bursting discs, also for third party products
- continuous temperature range: -30 °C to +220 °C (directly on leakage sensor)
- Can be delivered ex works

Note on ATEX:
All burst indicators / leakage sensors from STRIKO according to the type of protection are rated “i” intrinsic safety – “simple electrical equipment” when connected to an intrinsically safe circuit. The requirements on “simple electrical equipment” are covered in section 5.7 of the standards EN 60079-11:2012 or IEC 60079-11 Ed. 6:2011-06 “Explosive atmospheres – Part 11: Equipment protection by intrinsic safety ‘i’”.
Simple electrical equipment, designed in accordance with the requirements of section 5.7 of the standards EN 60079-11:2012 or IEC 60079-11:2011 and section 16.4 of the standards EN 60079-14: 2014 or IEC 60079-14 Ed. 5: 2013-11 “Explosive atmospheres – Part 14: Electrical installations design, selection and erection” do not require certification; see section 4.4.2 of EN 60079-14: 2014 or IEC 60079-14 Ed. 5: 2013-11.
Such parts are also not governed by directive 94/9/EC since they do not feature any potential source of ignition. The designation of simple equipment can be made by any person/institution, including the manufacturer or installer, and made by freely selectable designation marking or coding preferred for the installation/plant.
