The TH-9120A lidar performs 3D high-precision scanning of stationary targets, with a scanning cycle ranging from 3 to 64 seconds(adjustable),
such as scanning the internal contour and vehicle posture before automatic loading.
The TH-91 series is supporting both indoor and outdoor applications. It is a 3D scanning type, with the maximum line scanning frequency up to 50Hz and the minimum line scanning angle resolution of 0.125°. It adopts industrial-grade protective design, which can meet the strict requirements for precision and reliability of mining and metallurgical industries in applications such as loading monitoring, automatic coiling, material level height, material level volume, and 3D point cloud.
