How to choose the corresponding precision image measuring instrument according to the product?

   Image measuring instrument is a new high-precision, high-tech measuring instrument integrating optical, mechanical, electrical, and computer image technology. It is widely used in machinery, electronics, instrumentation and other industries. At present, there are many brands and models of image measuring instruments on the market, and there will be differences between them. So, how do we choose image measuring instruments with corresponding accuracy according to the product?

  1 According to the batch size of the workpiece: use ordinary image measuring instruments for small batches; use gauges and inspection fixtures for large batches to improve measurement efficiency.

  2. According to the structure and weight of the workpiece: light, small and simple workpieces can be measured on the measuring instrument, and for large and complex workpieces, the upper-mounted measuring instrument is used, that is, the measuring instrument is taken to the workpiece measuring.

  3. Determine the specifications of the image measuring instrument according to the size and requirements of the workpiece, so that the measuring range of the measuring instrument can accommodate the workpiece and the measuring head can extend into the measured part.

  4. Choose the image measuring instrument according to the required error (tolerance) of the workpiece. Generally, the maximum allowable error of the image measuring instrument is 1/3~1/10 of the tolerance of the workpiece. If the measured workpiece is a measuring device, its tolerance 1/10 must be selected; if the measured workpiece is a general product, its tolerance 1/ 3~1/5; if the measuring instrument conditions do not allow it, it can also be 1/2 of its tolerance, but at this time the confidence level of the measurement result drops accordingly.

   5. When selecting the sensitivity, it should be noted that the sensitivity of the image measuring instrument is too low will affect the accuracy of the measurement, and it is too high and it is difficult to achieve a balanced state in time.

   The above content is carefully organized by Miaoji, I hope it will be helpful to everyone.
