1. Optical gas detector
The open-circuit (line of sight) gas detector for photoelectric integrated "spectral fingerprint" atmospheric analysis adopts the exclusive patented technology of differential absorption spectroscopy (DOAS). Differential ultraviolet/infrared slit filter sensor can detect, identify and determine the concentration of flammable and explosive gases escaping into the atmosphere, and can accomplish these tasks far below its explosion limit level. This system is specially developed for detecting flammable or toxic gases. It uses a flashlight or incandescent light source, which can communicate with the detector to respond to the change of optical density in the presence of gases. This optical gas detection system called "SafEye" has been successfully used in high risk/high output market.
2. Optical flame detector
The flame detector analyzes the electromagnetic radiation released by the flame in the far ultraviolet region and the infrared region by electron optics. This patented flame radiation signal spectrum analysis technology includes frequency domain and time domain analysis, as well as cross-correlation and ratio analysis of different sensor inputs. The unique background radiation analysis improves the detection accuracy of the flame detector in the changeable environment containing various emission sources. These background interferences include direct solar radiation, heating and combustion equipment, optical projectors, high-voltage electric sparks, welding arc radiation and extreme environmental conditions. This kind of optical flame detector called "SharpEye" has been developed and used in the safety equipment market and the high risk/high output fire fighting equipment market. SharpEye series products include ultraviolet, ultraviolet/infrared, triple infrared (IR3) and closed-circuit television optical flame detectors.
3. Explosion/fire condition detector
Explosion/fire conditions can be detected in advance by monitoring their environmental variables, such as temperature and pressure changes caused by gas decomposition, radiation released by decomposition, gas decomposition by-products, etc. In which decomposition by-products with very low concentration can be detected in the air. Combustion products such as carbon dioxide, carbon monoxide, various valence oxides of nitrogen and HC (unburned hydrocarbons) can be monitored at a very low concentration (PPM level), which provides conditions for early detection and reliable detection. SafEye optical gas analysis system includes ultraviolet and infrared special models.
4. Military explosive detection and fire extinguishing system
Spectrex has developed a fire and explosion detection and extinguishing system for safe military vehicles, which aims to protect individuals from skin burns and shock caused by high pressure. The system can extinguish the explosion caused by gas or steam in less than 150 milliseconds, and the reaction speed is less than 3 milliseconds. The fire extinguishing process is started, and the fire extinguishing agent is released and dispersed in less than 5 milliseconds, thus providing a uniform concentration of fire extinguishing agent. The system has been successfully applied to thousands of military vehicles in the world.
