What Is a Linear Gauge?
A linear gauge is a device used to measure the amount of displacement of an object to be measured.
It is used to measure the number of rotations of a shaft or to optically measure the amount of displacement of a device that is driven in a specific direction. It consists of a moving slit attached to the measurement target, two fixed slits, and a machine that counts the waveform of the slit as a pulse wave. The moving force of the measurement target is recognized as a pulse wave, and the degree to which the measurement target has moved by the number of waves can be measured. The measurement accuracy depends on the slit spacing.
Applications of Linear Gauges
Linear gauges are mainly used as sensors for machine tool control. Therefore, the industries in which they are used range from automobiles to home appliances, machine parts, logistics, and experiments. When selecting a linear gauge, it is necessary to consider the accuracy of the selection, its suitability for the environment in which it will be used, and whether it can be mounted. Examples of linear gauge applications are shown below.
- Measurement of shaft rotation speed in lathe equipment, milling machines, etc.
- Measurement of the travel of cutters and drills on lathes, drilling machines, milling machines, etc.
- Measurement of the movement of cargo in logistics plants
Principle of Linear Gauges
This section describes the principle of operation of linear gauges. A linear gauge is divided into two parts: the detection part, which uses a slit or similar device to detect the amount of change in the light waveform, and the counting part, which transforms the light waveform into a pulse wave and counts the number of pulse waves. The detection section consists of a light source, two fixed slits whose phases are offset by 1/4 pitch, and a moving slit that is attached to the measurement object. The counting section consists of a light-receiving element and a counter.
In operation, when the measurement target moves, light emitted from the light source passes through the two fixed slits and reaches the moving slit. The light that passes through the moving slit reaches the light-receiving element, and its waveform is measured. The two misaligned fixed slits cause the waveform to change, and the direction of movement is determined according to the amount of change in the waveform. The direction of movement is determined according to the amount of change in the waveform.
