How does a Dial Gauge work? 

This gauge, or indicator, operates on a simple principle to measure small distances or variations. Here's how it works:

i) This gauge consists of a movable plunger or probe connected to a gear mechanism.
ii) When the plunger comes in contact with the object being measured, it moves the gear mechanism.
iii) The gear mechanism rotates a needle or pointer on a calibrated dial, indicating the measurement.
iv) The accuracy of the gauge depends on the precision of the gear mechanism and the dial scale.
v) These gauges work by making direct contact with the object being measured. The plunger dial gauge or probe is pressed against the surface, and the resulting displacement is translated into a measurement.
vi) These gauges utilise a mechanical amplification system to magnify small displacements. This allows for increased sensitivity and precision in measuring minute changes.
vii) These gauges have a calibrated dial or scale that provides accurate readings. The scale is divided into units such as inches, millimeters, or degrees, allowing users to interpret the measurements with ease.
viii) These gauges are designed to provide consistent and repeatable measurements. The gear mechanism and internal components are built to ensure minimal friction and reliable performance.
ix) These gauges can be used in various applications, including engineering, manufacturing, metrology, and automotive industries. They are suitable for measuring dimensions, variations, alignments, and deviations in mechanical parts and assemblies.

There are range of  gauges available, including bore gauges, test indicators, and dial gauge measurements. Brands like Mitutoyo offer reliable options such as plunger gauges and digital gauges.
