TDLAS200 High-Sensitivity Laser Methane Sensor
1.Introduction
The KACISE TDLAS200 High-Sensitivity Laser Methane Sensor is
designed for precise methane detection with unparalleled accuracy.
Utilizing Tunable Diode Laser Absorption Spectroscopy (TDLAS)
technology, it offers a detection range of 0~5000ppm and a static
detection limit of 0.5ppm. Its high sensitivity ensures reliable
performance in various environments, with an operating temperature
range of -20~50℃. The sensor features a built-in reference cell for
automatic calibration and a compact design for easy integration.
KACISE combines advanced technology and durability, making this
sensor ideal for industrial safety and environmental monitoring.
2.Features
3.Measuring Principle
"Methane molecules absorb light of a specific wavelength"
--Molecular absorption spectrum
"The amount of light absorbed by a transparent medium (methane gas
mass) is proportional to the thickness and concentration of the gas
mass" --Beer-Lambert's law
According to the above physical principles, a beam of light of a
specific wavelength can be used to penetrate the leaking methane
gas mass. According to the degree of weakening of the beam, the
concentration of methane in the gas mass can be measured, and it
only responds to methane (unique selectivity).
Using a detection cell with multiple reflections and allowing the
laser to repeatedly pass through the gas being measured can
multiply the detection sensitivity.
