Benefits of UV/IR Flame Detection

Flame detectors are required for flame risk working environments in industries such as oil and gas, industrial plants, and more to prevent potential fires, explosions, and toxic gas mixing with heat risks. More reliable than the average heat and smoke detector, flame detection systems can be applied to indoor and outdoor environments. 

There are two types of flame-sensing technologies used for flame detection systems: ultraviolet/infrared (UV/IR) and multi-spectrum infrared (MSIR). UV flame detectors consist of ultraviolet (UV) and infrared (IR) sensors paired within a single device. While the UV sensor detects UV radiation flames, the IR sensor monitors the infrared emissions. Flame detection is also very important for working environments containing hydrocarbons, found in applications such as industrial manufacturing and agriculture, chemical plants, and electric power plants. 

The alarm source shared between the two sensors is a real hydrocarbon fire, proven to be the key advantage of UV/IR detection systems. The advanced signal processing algorithms ensure the combination of sensors within the instrument delivers ultimate performance for a wide range of flammable liquids, gases, and volatile solids. Another benefit of UV/IR detection systems is the little to no false alarms, which is more useful since UV and IR sensors alone have higher risks of false readings. UV/IR flame detection devices also include continuous self-testing as well as configuration and diagnostic options, and easy calibration and maintenance procedures.

Otis Instruments offers the Omniguard 860 UV/IR Flame Detection system as well as other flame detection products to meet all your requirements and needs. The model 860 senses ultraviolet radiation and infrared radiation in the appropriate wavelengths for very early fire detection. And, using the patented Fire Event Analysis algorithm, is also able to distinguish between a real fire and non-fire events providing superior false alarm immunity. The technology has proven itself over decades of reliable service. The model 860 is available in two versions, one for hydrocarbon fires only, and one for hydrocarbon and certain non-hydrocarbon fires. This dual capability provides the unique capability of providing fire detection for a broad range of fuels with a single unit. Both versions are available with an automatic self-test function to monitor the detector’s ability to sense fires and report a fault condition when impaired.

Otis Instruments offers a vast selection of Wired and WireFree easy-to-use, robust, and configurable gas and flame detectors and monitors, capable of detecting both toxic and non-toxic gases and flammable environments for diverse applications.
