Length Measurement of Hot Steel Pipe

Older | Newer

A system integrator in Croatia worked closely with a steel pipe manufacturer to develop a system for measuring the length during production.  The clever solution incorporates an AR1000 laser distance sensor from Acuity to measure to the leading edge of the pipe during cutting.  The high-speed saw blade serves as the Zero Point Reference during the cutting process.  The pipe is stationary during cutting and gives a very stable reading.

A non-contact solution was required because the pipe is quite hot and still glowing orange.  The laser spot is perfectly aligned to measure to the edge of the pipe, on the surface between the inner and outer diameters.  The rangefinder is installed sufficiently far away from the heavy, moving pipe. This steel pipe manufacturer plans to use this solution on all of its production lines in the future because it saves time and reduces worker exposure to the hot material. For more information about this novel application of the laser distance sensor to measure pipe length, contact Contact Acuity Laser or Axium Europa d.o.o.
