Advantages in the application
- Use in high temperatures up to 600 ℃ (with sealing Frenzelit isoplan® 750®)
- High corrosion resistance through special materials
- Quick identification of a malfunction
- Simple assembly
- Available in nominal widths DN 25 to DN 600
- In every system can be combined with metal and graphite burst seals, also with bursting discs from other manufacturers
- Can be also used with bursting discs that can be attached without holder between the flanges.
- Retro-fitting possible thanks to low installation height of 5mm.
- The alarm is a separate component and independent of the burst disc
Note about 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.
