Product Details

1. Product Introduction

2. Infrared detection principle

Polar molecules such as CO2 and SO2 have permanent electric dipole moments, so they have structures such as vibration and rotation. The energy level of the split according to quantum mechanics can be coupled with the incident characteristic wavelength infrared light to produce absorption. The gas molecules have a selective absorption spectrum in the infrared light band. When infrared light of a specific wavelength passes through CO2 or SO2 gas, strong light absorption can be generated.

Since the detector converts optical signals into electrical signals, when the detector works in the linear region, selects a certain wavelength and determines the length of the analysis cell (absorbing cell), the concentration of the measured gas in the mixed gas can be calculated from the measured light intensity. This is the basic principle of infrared absorption method to measure the gas concentration quantitatively. The measured wavelengths selected by this instrument are: CO2 is 4.26um and SO2 is 7.4um.

The analysis chamber includes a miniature infrared light source, a mirror, a modulation motor, an absorption cell, a filter and a detector. The micro infrared light source is heated to 800°C to generate infrared light. After being absorbed by CO2 and SO2 through the absorption cell, it is then passed through a narrowband filter to remove the energy of other optical radiation outside the above wavelength and incident on the detector. Then the light intensity corresponding to the concentration of CO2 and SO2 is detected on the detector. The photoelectric conversion of the detector into an electrical signal,then normalized calibration is performed by the microcomputer, and the integral is inverted to the percentage of carbon sulfur elements. A modulation motor is placed between the light source and the absorber, modulating the light signal into an alternating radiation signal of 64Hz. The center frequency of the detector output is 64Hz.

The thermally-releasing device is converted into an electrical signal through pre-amplification and post-amplification and then entered into a microcomputer through digital-analog conversion. In the microcomputer, it is converted into a numerical value proportional to the CO2 and SO2 content through linear operation.
