1. Introduction: Principle of Gas Detection by Infrared Thermal Imagers
All objects with a temperature above absolute zero emit infrared radiation, and the intensity of this radiation is proportional to the object’s temperature. Infrared thermal cameras can convert invisible infrared radiation into visible infrared images through photoelectric conversion, thereby intuitively presenting the temperature distribution of the target area.
Gas molecules absorb infrared radiation in specific wavelength bands, and different gases have distinct absorption peak wavelengths. This creates an infrared radiation difference between the gas and the background. Based on this principle, Flint Technology’s gas imaging infrared thermal cameras adopt high-performance custom filter detectors to quickly identify infrared radiation differences absorbed by gases within characteristic wavelength bands. They convert invisible gases into clear.
2. Advantages of Gas Detection by Infrared Thermal Imagers
1) Gas Visualization for Rapid Leak Trace Location
Infrared gas imaging technology converts invisible leaking gases into visual images, serving as an important tool for gas leakage detection. It helps operation and maintenance personnel quickly lock in leak points and achieve precise positioning of gas leakage locations.
2) Efficient Inspection for Cost Reduction and Efficiency Improvement
Equipped with large-range and rapid scanning capabilities, it can complete detection in multiple areas within a short time, significantly improving inspection efficiency. Compared with traditional methods, it saves more labor input and operation and maintenance costs, helping build a more economical and efficient inspection and operation system.
3) 24/7 Online Monitoring for Uninterrupted Gas Detection
Online devices can realize 24/7 continuous monitoring, capturing abnormal gas leakage in real time and avoiding blind spots and omissions caused by inspection intervals in traditional manual inspections.
4) Non-Contact and Long-Distance Detection for Uninterrupted Safety
It supports non-contact and long-distance detection, allowing operation and maintenance personnel to complete detection tasks without approaching high-risk areas, thus effectively reducing operational risks. In addition, the detection process does not affect the normal on-site operation, achieving a win-win situation of “safe inspection + non-intrusive operation”.
5) Reliable Data Support for Assisting Scientific Decision-Making
Detection results can be output in the form of images or videos, intuitively presenting the location and diffusion status of gas. This facilitates risk level assessment, assists in formulating scientific disposal plans, and promotes the intelligence and refinement of inspection decision-making.
