An explosion-proof, fixed-mounted IP68 acoustic camera designed for applications such as gas leak detection and partial discharge monitoring.
Acoustic imaging + laser methane integrated explosion-proof PTZ camera (HZ-PA-3EX) is an explosion-proof integrated PTZ camera specially designed for gas leakage.
The product monitors gas leakage through multi-dimensional means, finds early leakage points, improves fault identification rate, and detects and analyses specific gas leakage scenarios.
The camera adopts the vibration signal generated by the scanning of the laser beam to judge the methane concentration to lock the scope of the gas leakage and then uses the acoustic sensor array to accurately locate the leakage position, and displays intuitive acoustic field images by means of a colorful sound point.
Chemical Plant Leak Monitoring Solution
Our ATEX-certified acoustic-laser pan-tilt system deploys across chemical complexes for dual-mode gas monitoring:
Above-ground pipeline networks: Detects fugitive emissions at flanges/valves
LNG storage perimeters: Quantifies methane concentration in ppm
Mission-Critical Capabilities:✅ 360° continuous scanning (70m range)✅ Synchronized leak localization + quantification✅ Autonomous patrol modes with GIS mapping
