Background technique

In the field of construction or product manufacturing, it is often necessary to measure the deformation and deflection of certain components, test blocks or products to determine whether the components, test blocks or products are deformed and the size of the deformation, which is a measure of their quality. an important indicator. Existing deflection measuring devices commonly use level gauges, measuring gauges, dial indicators, etc. The level instrument is inconvenient to measure in a short range, and when the object to be measured is at a higher position, due to the limitation of the tower ruler, the method of level instrument measurement is no longer applicable. The gage is not suitable for deflection measurements of deformed objects. The dial indicator is an expensive instrument. When in use, it is installed on the bracket and contacts the component to be measured. The value of its deflection is reflected on the dial indicator. It has high accuracy, but the measuring range is too small and the cost is high.
