NDIR Gasdetektor.

KLIMA/ATMOSFÆRE Ny teknologi til atmosfæremålinger

Transform Infrarød Spektroskopi (FTIR) og NDIR. I Picarros CRDS benytter analysatoren et ekstremt fi nt 3-spejl optisk kam-mer (Cavity), der giver en lysvejslevetid på ca. 40 µs, hvilket svarer til en lysabsorptionslængde på ca. 12 km. Det andet særkende er målingen af det optiske tab. I konven- tionel optisk absorptionspektroskopi måles lysintensiteten før og efter prøven. I CRDS m

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

Nondispersive infrared (NDIR) spectroscopy is often used to detect gas and measure the concentration of carbon oxides (for example, carbon monoxide and carbon dioxide). An infrared beam passes through the sampling chamber, and each gas component in the sample absorbs some particular frequency of infrared. By measuring the amount of absorbed infrared at the appropriate frequency, the …

Infrared open-path detector - Wikipedia

Beginning in 1985, Shell Research in UK was funded by Shell Natural Gas to develop an open-path detector with no moving parts. The advantages of the μm wavelength were identified, and a research prototype was demonstrated. This design had a combined transmitter-receiver with a corner-cube retroreflector at 50 m.

Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.
