1. Laser-focused on gas detection
Optical infrared (IR) sensors detect gas leaks—even the smallest concentrations, without interacting with the gas.
The gas sensor market is a complex combination of multiple technologies and applications, but the increasing desire to detect and monitor within different fields demands the development of innovative sensing systems.
Many drivers are causing the overall market to grow, ranging from the consumer demand for the digitization of air quality, data quality, and new manufacturing methods to print sensors, and even vehicle electrification.
Laser spectroscopy-based techniques have led the charge, owing to their high sensitivity, noninvasiveness, and in situ real-time observation. Further improvements in laser sources and detectors have opened a whole new world of opportunities for laser spectroscopy-based sensing and detecting techniques.
Gas is always serious business, and when it comes to methane leak detection, the performance of instruments used for the safety or maintenance checks carried out on natural gas installations needs to be constantly upgraded to meet the latest operational and regulatory requirements.
How do IR solutions measure up?
IR emitters within the sensor generate beams of IR light. And, once passed through a sampling chamber, a filter in front of the detector blocks out light that is not at the desired wavelength while the detector measures the intensity or attenuation. This is then used to determine the concentration based on the absorption of IR radiation as it passes through a volume of the gas.
