Laser Profiler

Laser Pipe ProfilingLaser Pipe Profiling

For pre and post inspection using “spinning laser” profiling technology. It is a 3 in 1 system, a single module upgrade to the L135 tractor / crawler platform. Two laser diodes are integrated on either side of the conventional CCTV camera lens to perform three functions:
  • Conventional CCTV video pipe inspection
  • Laser profiling – precise measurement of diameter, deflection and deformation of pipe.
  • Crack & joint measurement

Standard application range from 8″ up to 48″ pipe diameter (up to 72″ diameter requires additional equipment & upgrades)

Advantages of the Rausch Laser Profiler

  • Integrated into camera module
  • Mounts onto the L135 tractor platform
  • Direct & highly accurate measurements
  • Instant & final reports on site with POSM Pro software
  • No third party analysis
  • No field calibration necessary
  • Instant system verification
  • Quick & easy setup

How it Works

The Rausch Laser Profiler features two laser diodes that are integrated into the KS135 Scan camera head. When these laser diodes project laser dots onto the inner pipe wall, the camera head rotates to measure the diameter and all changes thereof via triangulation calculations. This method is called the “spinning laser” laser pipe profiling technology. Working in conjunction with the POSM software, the comprehensive scan generates easy to use reports to profile the pipe.

Detailed Operation

On the way into the pipe, the system is used to perform conventional CCTV video inspection, as well as measuring all joint widths. In addition, individual laser measurements can be taken at any time to determine the actual pipe diameter and deflection, called a single point scan. These diameter and deflection measurements then become a part of the inspection report.

On the way out of the pipe, the system performs a “spinning laser” scan of the entire pipe length. The camera head swivels perpendicular to the pipe wall and rotates at a defined speed. Via triangulation the Scan software continuously calculates the precise pipe diameter and all deflections and deformations in the pipe profile. Once the run is completed, the software instantly generates graphs in 2- and 3-D. These graphs show any deflection, the average pipe diameter, and the inclination slope of the line.
