The importance of NDIR carbon monoxide sensor

Overview

Carbon monoxide is an air pollutant. It is the richest and most widely distributed in the atmosphere. It is the product of incomplete combustion of carbonaceous materials such as coal and petroleum. Mainly from the production process of coking and ironmaking in the metallurgical industry; production processes of chemical synthesis of ammonia and methanol; mine blasting and coal mine gas explosion accidents; exhaust emissions from vehicles and other vehicles; incomplete combustion of fuel in boilers; gas or liquefied gas pipelines from homes Carbon monoxide released from natural disasters such as coal stove leaks. Volcanic eruptions, forest fires, earthquakes, and earthquakes. In addition, chemical reactions in the upper atmosphere, slight dissociation of carbon dioxide. And animal metabolism also produce a small amount of carbon monoxide. Therefore, it is necessary to use a carbon monoxide sensor to detect.

NDIR carbon monoxide sensor

Jingxun Changtong Carbon Monoxide Sensor is a sensor that uses non-dispersive infrared technology (NDIR) to measure carbon monoxide.

The infrared radiation emitted by the infrared light source is absorbed by the gas to be measured. The spectral intensity proportional to the gas concentration will change. Therefore, the change in the spectral intensity can be used to inverse the concentration of the gas to be measured. The infrared carbon monoxide sensor module adopts the principle of NDIR infrared absorption detection. Combining advanced optical circuits, precision circuits and intelligent software to form a universal infrared CO sensor module.

This product adopts imported MEMS infrared light source and dual-channel pyroelectric detector to process measurement and reference signals. And perform temperature compensation. Even under harsh temperature and environmental conditions, stable and reliable measurement results can be obtained. It has the characteristics of good selectivity, high sensitivity. No oxygen dependence, and long life that are unique to NDIR products.

JX-CO-103 series products are made of aluminum alloy polishing process and production. This product can be widely used in coal mine gas detection, oil and gas detection. Chemical gas production and air detection process monitoring, and can be installed in chemical, coal, oil fields, intelligent buildings. Sound and light alarm controllers, robots, automobiles and other applications.
