optical methane detector

Methane detection -

Methane is produced by many natural and human-influenced sources. There are several different techniques of methane detection. We offer method of mid-infrared optical absorption based on LED-PD optopair. Methane has the main absorption band at 3200-3400 nm. Weaker absorption bands that can be used for detection are located around 2300 nm and ...

The Science Behind Optical Gas Imaging | Teledyne FLIR

An optical gas imaging camera can be considered a highly specialized version of an infrared or thermal imaging camera. There is a lens, a detector, some electronics to process the signal from the detector, and a viewfinder or screen for the user to see the image produced by the camera. The detectors used for OGI cameras are quantum detectors that require cooling to cryogenic temperatures ...

A Review of Methane Gas Detection Sensors: Recent ...

An example of an in situ optical methane sensor is a mobile methane sensor mounted on a vehicle to detect methane leaks along the natural gas pipelines. When the sensor detects methane, audio and visual signals are sent to a display inside the vehicle to alert the operator. The remote methane sensors also detect methane using IR spectroscopy but without the need for a gas sample. These sensors ...
