Flame Detectors

Continuously be protected! Prevent fire catastrophes by detecting and initiating fire prevention measures within seconds of fire ignition with automatic flame detectors.

What are flame detectors?

Flame Detectors are electronic devices that use optics to "see" a fire from a long distance without the smoke or heat needing to get to the detector first. The four primary optical flame-sensing technologies are: ultraviolet (UV), ultraviolet/infrared (dual), Infrared (IR), and visual flame imaging. They are all based on line-of-sight detection of radiation emitted by visible yellow/red flames and heat as shown in the UV, visible light, and IR spectral bands.

Optical flame detectors employ optical sensors, working in a specific spectral range and record incoming radiation at the selected wavelengths.
The Signal recorded by each sensor is analyzed according to pre-determined techniques:



When configuring flame detection systems it is useful to consider the following flame detector performance criteria’s:





Single IR Flame Detector

Description:

Specifically devised for detection of hydrocarbon and hydrogen flames at long distances - gasoline pan fire at 65m or a hydrogen flame at 30m in less than 5 seconds. Superior performance, reliability at long distances with the highest immunity to false alarms - These flame detectors are well equipped for locations where combustion sources create smoky fires.



Triple IR (IR3) Flame Detector

Description:

Triple IR flame detector utilizes digital signal processing to examine the dynamic and spectral properties of the measured infrared radiation, to recognize fire events with unprecedented sensitivity and exceptional immunity to false alarms.



Ultraviolet Flame Detectors

Description:

Ultraviolet (UV) Flame Detector detects hydrocarbon-based fuel and gas fires, invisible hydrogen flames, silane, ammonia and other organics. This type of detector is mostly used for indoor applications and should not be exposed to UV radiation sources such as electric arcs, welding, and sparks in order to reduce false alarms.



Dual Ultraviolet and Infrared Flame Detector

Description:

The UV/IR flame detector utilizes a combination of UV and IR sensors to detect hydroxyl and hydrogen fires, hydrocarbon-based fuel and gas fires, as well as metal and inorganic fires. To verify the reliability of the fire signal - the UV radiation threshold signal, the IR threshold signal, their ratio as well as their flickering mode is compared. Only when all parameters satisfy the detection mathematical algorithm is a fire alarm triggered.



CCTV Flame Detectors

Description:

A self-contained, triple-spectrum, optical flame detector that incorporates a colour video camera. Combination of triple infrared sensor technology maximizing identification of flames with high immunity to false alarms, and video monitoring allowing user to verify and react to the situation.







Infrared flame detection

An infrared optical flame detector locates flames by deploying Infrared sensors to identify Infrared radiation with their specific spectral pattern emitted by fire.

IR flame detectors are suitable for locations where combustion sources can produce smoky fires. They can operating at moderate speeds and within a range of up to 60 meters from the flame source — both indoors and outdoors. These Flame detectors showcase high immunity to infrared radiation produced by arc welding, lightning, sunlight, and other hot objects that might be encountered in industrial backgrounds.





Ultraviolet flame detection


Ultraviolet flame detectors identify flames by their radiation emitted with the use of ultraviolet sensory technology. UV detectors respond to radiation in the spectral range of 180-260 nanometres at high speeds: 3-4 milliseconds. They offer quick response and good sensitivity at short ranges.





Dual UV/IR flame detector


A dual band detector, combination of Ultraviolet and Infrared sensors sensitive to the UV and IR radiation emitted by a flame. IR sensor operates at a wavelength of 2.5-3.0 µm, and can detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic fires. The UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. Simultaneous detection of radiant energy in both the UV and IR sensors triggers an alarm signal.





Flame imaging detection (Triple IR)


CCTV Flame imaging detector utilizes Infrared sensor technology to identify flames which then can alert the operator of the danger, the operator can then locate and verify if further measures are necessary via the live video input.

Constructed with Triple Infrared sensors to ensure the greatest degree of spectral matching to the radiant energy emissions of fire with the lowest degree of matching to non-fire stimuli.

A colour video camera with video signals of either NTSC or PAL - enables the user to investigate the monitored area, identify the fire’s source and location, and help select the best response (activation of fire suppression) to the situation .

Infrared Flame Detectors


With its technology dating back to the 1800’s and still extendedly used today there is no doubt in the reliability of our ultraviolet flame detectors to expose a fire effectively.

Operation:

IR flame detectors are suitable for locations where combustion sources can produce smoky fires. They can operating at moderate speeds and within a range of up to 60 meters from the flame source — both indoors and outdoors. These Flame detectors showcase high immunity to infrared radiation produced by arc welding, lightning, sunlight, and other hot objects that might be encountered in industrial backgrounds.

Advantages:

IR Flame Detectors incorporate a heated optical window for better operation in condensation, icing and snow conditions. These Weather resistant, most durable flame detectors can be easily tweaked for all applications, environments, and requirements, by simply changing the configuration parameters. Modifying these parameters, as well as conducting monitoring tasks and maintenance, is possible by means of RS485-based Modbus communication or Highway Addressable Remote Transducers (HART).

IR detectors deliver extended coverage that allows the use of fewer detectors. Its high reliability provides a very low cost of ownership. These Infrared detectors are devised to operate as a stand-alone unit connected to an alarm system or an automatic fire extinguishing system - can also be integrated through a common control unit.
