In recent years, the application scope of laser technology has been expanding. Among them, the laser methane detector is a commonly used instrument. It utilizes laser characteristics to detect methane concentration, and identify the leakage point, with advantages such as high sensitivity and rapid response. The advantages of mounting a laser methane detector on the DJI M350 drone are evident.
I. Advantages of DJI Matrice 350 drone Laser Methane Gas Detection
Compared to other types of methane gas detection technologies, laser methane gas detection technology and products have the following significant advantages:
- High Sensitivity: Laser methane detectors can accurately measure methane concentrations at very low levels. Their sensitivity can reach parts per billion (ppb), meeting the demanding requirements of environmental monitoring.
- Rapid Response: Laser methane detectors have the characteristic of rapid response, enabling measurement of methane concentrations within milliseconds. This allows for the timely detection of anomalies and appropriate action.
- Non-Contact Measurement: Laser methane detectors employ a non-contact measurement method, eliminating the need for sample contact or chemical reactions. This avoids the issues of traditional instruments being susceptible to external contamination or damage. Traditional methane gas detection technologies may only detect low concentrations of gas or high concentrations of gas. However, in many practical applications, customers require a wide dynamic measurement range. Using chemical transmitters would necessitate the installation of sensors with different ranges, increasing both cost and inconvenience. Laser sensors, on the other hand, have a measurement range from 0 to 100% VOL, meeting the needs of the vast majority of market applications and customers.
- Detection ranges up to 300M, with a 4K visible light camera.
II. Detection Principle of Laser Methane Gas Detection
The DJI M350 Laser Methane Detector is a lightweight natural gas leakage inspection payload. This payload utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology to detect air methane (CH4) components. Integrated into unmanned aerial systems, it achieves non-contact detection. The payload also integrates visible light sensors and laser rangefinders, enabling visual inspections and real-time accurate positioning of leak coordinates. The methane gas detection sensor has become a safe, efficient, and precise productivity tool in the natural gas inspection process, significantly reducing the workload of inspection personnel.
