·  Plate tilt automatic correction,can avoid the influence of steel plate wave and tilt on thickness measurement. Excellent dynamic measurement performance. The results of online measurement are the same as those of offline calibration.

·  Accurate lateral same-plate difference scanning curve .In the transverse differential scanning measurement, due to the change of the levelness of the roller table and the measuring slipway, the inevitable existence of the bending of the steel plate, making the transverse differential scanning measurement effect of the same plate generally poor. None of the domestic laser thickness gauge can measure the transverse difference scanning of the same plate, forming the transverse difference scanning curve of the same plate. The lateral change error of the best ray thickness gauge in the world is 0.1% of the thickness measurement change.

·  The use of unique anti-thermal expansion and contraction of the proprietarytechnology, greatly improve the thermal stability.

·  Use area array image sensor instead of the traditional linear array image sensor.Replace point sampling with area sampling. Thickness was measured by machine vision two-dimensional measurement. Machine vision thickness gauge can greatly reduce the measurement error caused by rough steel plate, small oxide skin, debris dust and so on. With the unique image processing algorithm, the measurement accuracy can be greatly improved.
