A measurement system for profile of hot-rolled sheet based on laser triangular principle is introduced in this paper. The measurement of the thickness of a single point of the sheet is realized and the profile is thus calculated accurately. With this method, the measurement accuracy is enhanced and the goal of environmental protection is achieved. Using top-and-bottom surface differential measurement structure with dual-triangular laser, the system greatly reduces disturbances llke vibration and so on. The system can work smoothly under severe environmental conditions, A specially designed transducer not only improves the measurement accuracy, but makes some adjustment automatically to different surfaces of the sheet as well. The system has a wide application and is easy to use. Experimental results show that the system＇ s measurement accuracy has been up to 3μm, which can fully meet the require- ment for high accuracy measurement.
