Calibration of steel straightedge test bench

The steel straightedge checker table is a special equipment for checking the accuracy of steel straightedge. In industrial measurement, dimensional accuracy is critical to product quality and productivity. Therefore, it is very important to check the accuracy of steel straightedge to ensure accurate measurement results and quality production. The following is a detailed description of the calibration of the steel straightedge calibration table.

What kind of measurement method is used for steel tape measure

Standard steel tape measure What kind of measurement method is used for steel tape measure

In the use of steel tape measure, the main reasons for the error are as follows

General steel tape measure thermal expansion coefficient of α = 1.25x10-5, for each meter per degree temperature change of only one in eighty thousand, but the same steel tape measure in the temperature difference between the environment or will produce a large length change, affecting the measurement results. The error of temperature variation has been considered in the equation of ruler length.

What is a steel tape measure? What are they used for?

A steel tape measure is also called a box rule. It is an ordinary measuring tool for measuring length. According to the different structure of its tape box, the tape measure is divided into four kinds of self-rolling tape measure, brake type tape measure, shake the tape box type tape measure and shake the tape frame type tape measure. Self-rolling tape measure and braking tape measure are mostly below 5m tape measure; the nominal length of rocking tape measure and rocking tape measure is more than 5m. Steel tape measure category steel tape measure nominal length: for the steel tape measure below 10rn to take o. 5 integer times; for more than 10m steel tape measure, to take 5 integer times. Tape measure specifications are Im, 2m, 3m, 3.5m, 5m, 10rn, 15m, 20m, 30m, 50m, 60m, 70m, 80m, 100m, etc.. Steel tape measure can be used to roughly measure the length, width, height, thickness and other dimensions of large workpieces, and can also be applied in geodesic measurement.

Pressure vessel common inspection apparatus of steel tape measure

Steel tape measure is one of the commonly used length measuring instruments in the geometric dimension inspection of pressure vessel manufacturing site.

Origin of steel tape measure

In the annals of the world's technological inventions, China also invented the steel tape measure, invented in the ancient Huizhou (present-day Huangshan City) in Anhui Province. This exciting and little-known information was learned when we revisited the memorial of the former residence of Cheng Dawei, a Ming Dynasty mathematician, bead mathematician and inventor.

Steel tape measure distance

Common distance measurement methods include tape measure and photoelectric distance measurement. Tape measure is to use a tape measure that can be rolled up / test big / along the ground measurement, belong to direct distance measurement. Photoelectric distance measurement is to use the instrument to transmit and receive modulated light waves between two points to determine the distance according to its propagation speed and time, which is electrophysical distance measurement. Optical distance measurement belongs to indirect distance measurement.
