The core advantages of infrared gas leak detectors are reflected in five aspects: non-contact remote detection, high-sensitivity visual positioning, efficient safety inspection, anti-interference adaptation to complex working conditions, quantitative leakage and preventive maintenance. The specific analysis is as follows:
1、Non contact and long-distance detection capability
Infrared gas leak detectors can detect leaks from tens to hundreds of meters away, without the need to be close to high-pressure, high-temperature, or toxic gas areas (such as high-altitude pipelines and chemical plant reactors). For example, the Hanwei R10 handheld detector can detect distances up to 20 meters, and the T-800 airborne system can achieve large-scale rapid screening through unmanned aerial vehicles, avoiding direct contact with hazardous environments and significantly improving safety.
2、High sensitivity and visual positioning
The device can detect trace leaks at PPB level (one billionth) or PPM level (one millionth), and visually display the gas plume morphology and diffusion direction through thermal imaging. For example, the LUFT300 VOC gas infrared leak detector uses a type II superlattice cooling detector, which can locate small VOC leakage points in real time; The Fujirui infrared leak detector uses a 320 × 256 medium wave refrigeration detector to accurately identify gas leaks such as SF ₆ and methane, reducing blind inspection time.
3、Efficient inspection and safety protection
Compared to traditional spot check sensors, infrared leak detectors can capture real-time images and quickly scan large areas such as storage tank areas and gas transmission stations, resulting in several times higher efficiency. For example, the Hanwei R10 single point inspection only takes 3-5 seconds and has passed the Ex iC IIC T4 Gc explosion-proof certification, making it suitable for high-risk scenarios such as petroleum and petrochemical plants and gas plants, reducing personnel exposure risks.
4、Anti interference and adaptation to complex working conditions
Infrared technology is not affected by strong electromagnetic, high temperature and pressure, or severe weather conditions, and can work stably in complex environments such as refineries and offshore oil and gas platforms. For example, the Jiuzhiyang portable VOC detector has passed safety and explosion-proof certification, and can accurately identify methane and hydrocarbon leaks even under strong electromagnetic interference; The T-800 system is equipped with a high-precision three-axis image stabilization gimbal to ensure image stability during drone inspections.
5、Quantitative leakage and preventive maintenance
Advanced thermal imaging cameras can estimate leakage rates (taking into account parameters such as gas type and distance) and assist in priority sorting. For example, when using an infrared leak detection imaging device to detect SF ₆ leaks, the accuracy can reach 0.001 mL/s, helping companies detect small leaks in advance and prevent accidents from escalating. Regular inspections can also meet environmental regulations (such as the EPA Method 21 alternative) and safety production requirements, reducing environmental risks and economic losses.
