Ultra Violet Flame Detection

FlameSpec-UV-IR model - UVIR flame detector providing ultra-fast response, high performance and reliable detection of a large variety of fires including hydrocarbon fires (visible and nonvisible), as well as Hydrogen fires. ​The detector addresses slow growing fires as well as fast eruptions of fire using improved UV IR technology. The detector operates in all weather and light conditions.​

FlameSpec-UV-IR-F model  - Same As FlameSpec-UV-IR but does not see hydroxyl and hydrogen  fires and IR sensor that operates at a wavelength of 4.0-5-0μm​.

FlameSpec-UV-IR-HD and UV-IR-F-HD models - ​In addition, the detector provides high-definition (HD) video output of the monitored area with clear imaging of a fire event and of personnel at distances up to 30m.This allows the rescue team to be aware of the exact situation before entering the hazardous area. The detector automatically records video of any fire event (1 minute pre- and up to 3 minutes post alarm initiation). These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews.

• Hydrogen, Inorganic and Hydrocarbons flame detection.  
• Ultra-fast detection mode detection within 5  milliseconds for fireballs or explosions.
• High sensitivity - up to 30m for a square foot n-heptane pan fire.
• High immunity to false alarms.
• Data/Event logger - alarms, faults and other relevant events are logged to non-volatile memory.  
• Ethernet communication – in addition to the standard methods, such as 4-20mA and Modbus.
• Built-in-Test  (BIT) - Automatic and manual internal self-test of window cleanliness  and the overall operation of the detector (for both IR and UV channels).  
• Window heater to avoid condensation and icing.
• Tilt mounting bracket can be connected either above or below the detector.
• Configurable detection mode – allows configuration of UV-IR, UV or IR detection modes.  

FlameSpec-UVIR–HD and UVIR-F-HD only:

• HD video output with Automatic HD video recording of fire events. Visualization of hydrogen flames that are invisible to the human eye.  
• Ethernet communication – in addition to the standard methods, such as Relays, 4-20mA and Modbus.
