Measuring instruments can be divided into mechanical measuring instruments, optical measuring instruments, electric measuring instruments, pneumatic measuring instruments, etc. according to the principle of signal conversion.

Mechanical gage and measuring instrument, a measuring instrument that uses mechanical methods to achieve the conversion of the original signal, such as a micro-motion screw type micrometer, lever comparator, mechanical tooth measuring instrument, etc., has a simple structure, stable performance, and convenient use.

Optical measuring instruments, such as optical comparators, projectors, etc., that use optical methods to achieve the conversion and amplification of original signals. This kind of instrument has high precision and stable performance.

Electric measuring instrument, a measuring instrument that converts the original signal into electricity to achieve geometric quantity measurement, such as inductive comparator, electric profiler, roundness meter, etc. Its characteristics are high accuracy, easy to realize automatic data processing and display, and can be used for computer-aided measurement and automation.

Pneumatic measuring instrument, which uses compressed air as the medium, and realizes the original signal conversion through the change of the state of the pneumatic system, such as water column pneumatic measuring instrument, buoy pneumatic measuring instrument, etc. This kind of measuring instrument has a simple structure and can be used for long-distance measurement. It can also measure parts that are difficult to measure with other conversion principles (such as deep hole parts).

There are many applications of measuring tools. According to different purposes, they can be divided into standard measuring tools, universal measuring tools, special measuring tools, and tools can be divided into mechanical measuring tools, optical measuring instruments, and electric according to different principles. Measuring instruments, pneumatic measuring instruments, etc. Measuring instruments bring great convenience to the project in construction applications.
