Scanning laser gas telemetry instrumentIt is a gas leak monitoring device based on laser absorption spectroscopy (TDLAS) technology, which achieves long-distance and high-precision gas concentration detection through non-contact measurement. It is widely used in fields such as petrochemicals, natural gas, and urban pipeline networks.
The core indicators of anti-interference ability of scanning laser gas telemetry instrument are:
Spectral selectivity:
Using tunable diode laser absorption spectroscopy (TDLAS) technology, target gases are detected through specific wavelength lasers (such as methane 1653.7nm), which only respond to target gas molecules and avoid interference from other gases (such as ethylene, carbon dioxide) or environmental dust.
Environmental adaptability design:
Meteorological correction: The built-in temperature and humidity sensor automatically compensates for changes in environmental parameters, maintaining a measurement accuracy of ± 10% even in rainy and foggy weather.
Penetrativity: It can monitor indoor gases through glass windows, solving the problem of permission limitations in traditional detection.
Temperature range: The working temperature should cover -30 ℃~60 ℃, and the humidity should be adapted to ≤ 98% RH (no condensation).
Dynamic anti-interference performance:
Stability of pan tilt scanning: The pan tilt with a horizontal angle of 360 ° and a vertical angle of ± 90 ° should maintain positioning accuracy under strong winds or vibrations to avoid mechanical errors affecting the detection results.
Algorithm optimization: Adopting anti-interference algorithms to eliminate signal noise in complex environments such as direct sunlight and double-layer glass.
