Description
Technical Description – SpyGlass SG50-F-IR3-H2 Triple IR Hydrogen Flame Detector
The SpyGlass SG50-F-IR3-H2 is the next generation of the IR3. It is being introduced to further enhance the protection and safety for these high risk and high value industries.
The SG50-F-IR3-H2 will detect hydrogen fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimizing the consequences!
A closer look
The unmatched detection times and distances are:
- Detection within 40 milliseconds of fireballs or explosions
- 5s for 32″ (0.8m) hydrogen fire at 0–66 ft. (0–20m)
- 4s for 32″ (0.8m) hydrogen fire at 66–100 ft. (20–30m)
- High immunity to false alarm
- Ultra-fast detection mode detection within 40 milliseconds for Hydrogen fireballs or explosions Hydrogen flame detection
- High sensitivity – up to 100 ft. (30m)
- Data/Event logger – alarms, faults and other relevant events are logged to non-volatile memory
- Built-in-Test (BIT) – Automatic and manual internal self-test of window cleanliness and the overall operation of the detector
- Window heater to avoid condensation and icing
