Optical Flame Detection

Flame detector and flame detectionSierra Monitor provides a full range of Industrial Flame Detectors designed to meet the needs of fire and safety professionals. The Sierra Monitor optical flame detectors, are top-of-the-line models featuring dual and tri-spectrum designs to provide a full range of capability. Each of the Sierra Monitor flame detectors provides 120 degree cone of vision.

Sierra Monitor is also a distributor of Spectrex Sharpeye 40/40 Series Flame Detectors under the SMC 3600 Series name,, offering our users a wide range of UV/IR and Triple IR Flame detectors in addition to the UV/IR/Visible and Semiconductor Web Bench Flame Detectors that we have been providing for many years. The Spectrex Flame Detectors have a 90 degree cone of vision.

Sierra Monitor Flame Detector

Industrial Flame Detector (3100 Series)

A tri-spectra design incorporating Ultraviolet, Infrared and Visible spectrum provides continuous and reliable flame detection. 120 degree cone of vision is provided, the largest in the industry.

Semiconductor Wet Bench Flame Detector (3200 Series)

Designed for the harsh conditions that can be found in a semiconductor manufacturing wet bench application.

UV/IR Flame Detector (3300 Series)

Designed for indoor applications, in a non-hazardous area such as a warehouse, exhibition hall or office spaces. The Model 3300 is ideal for use in areas where short line of sight is a factor.

3600 Series Spectrex Flame Detector

3600 UV/IR Spectrex Flame Detector (40/40 Series)

The 3600 UV/IR Series is available in two versions. The Model 3600L (& LB) detects hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic first. The Model 3600L4 (& L4B) is identical to the 40/40L except that the IR sensor works at a wavelength of 4.5 µm and is only suitable for hydrocarbon-based fires.

Spectrex Flame Detector3600 Triple IR (IR3) SpectrexFlame Detector (40/40 Series)

The 3600-I Triple IR (IR3) Flame Detector detects fuel and gas fires at long distances with the highest immunity to false alarms. The 3600-I can detect a 1 square foot gasoline pan fire at 215 ft (65m) in less than 5 seconds.

3600 Multi IR Spectrex Flame Detector (40/40 Series)

The new 3600-M Multi IR Flame Detector is specifically designed for detection of hydrocarbon and and hydrogen flames. It detects hydrocarbon-based fuel and gas fires at long distances with the highest immunity to false alarms. It features include a heated window, to eliminate condensation and icing, HART capabilities, for digital communications, lower poewr requirements, and a compact, lighter design.
