3 Best Dial Indicators In 2022

Updated Oct 14, 2021

Dial indicators are one of the essential measuring tools used in accurate engine building. They are generally used for crankshaft thrust and straightness, measuring deck clearances, lifter travel, and other measurements involving the distance between two areas or small amounts of component travel. The dial indicator normally reads in 0.001-inch increments over a range of one inch. Most builders use an indicator with 0.250-inch total travel which is enough for many accurate measurements.

The indicators refer to different types of instrument gauges used to determine the diminutive distances and angles, intensifying them to make them clearer. The tool provides an indication to the user which they cannot see.


Types of Dial Indicators

There are two types of dial indicators, the horizontal and the vertical.

The main difference between the two is on how the dial meter is mounted and how it works.

The horizontal test indicators provide measurements with the use of level arms while the vertical test indicators measure with a plunger.

The Difference Between Dial Indicators and Test Indicators

The test indicators use lever contacts while the dial indicators use plunger contacts. Test dial indicators are lightweight and smaller than dial indicators. They have overlapping uses but are most of the time used for separate tasks.

Dial indicators are recommended for comparative and repetitive measurements. If it is fixed in a fixture gauge, the straight, vertical movement ensures that relative to the fixture, the contact always settles in the same area.

The test indicators are used to gather consistency measurements, rather than comparative ones. They are usually used to interpret broad part areas, usually one or two dimensions. An example of this is height, roundness, or flatness variations.
