TDLAS200 Methane Sensor with Multi-Reflection Detection Cell

1.Introduction

The KACISE TDLAS200 Methane Sensor with Multi-Reflection Detection Cell enhances sensitivity by allowing the laser to pass through the gas multiple times. It offers a detection range of 0~5000ppm and a response time of 0.1 seconds, ensuring accurate and reliable measurements. The sensor features a compact design and a digital interface for easy integration. With an operating temperature range of -20~50℃, it is suitable for various environments. KACISE combines advanced technology and durability, making this sensor a trusted choice for methane detection.

2.Features

1. High sensitivity, only responds to the target gas
2. Built-in reference cell, can be automatically calibrated
3. Easy to integrate, digital interface directly outputs status and concentration

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.
