What Is a Dial Indicator?
A dial indicator is a measuring instrument for measuring the length and runout of a workpiece. Some products have the same shape and function and are named dial gauges.
It is placed on a foundation and measures the workpiece to determine the dimensional difference from an exemplar (such as a block length gauge). The scale to be measured can be in hundredths of a millimeter or thousandths of a millimeter. If the temperature is not controlled, the measurement method, the condition of the foundation and workpiece, etc., are not controlled, the measurement will not be made with the desired accuracy, and a significant error may occur.
Uses for Dial Indicators
Applications include:
- Measuring parts used in precision instruments.
- Measuring relatively small-diameter components.
- Measuring the runout of circular parts.
First, set the base to be fixed on top of the base, and place dial indicators or gauges on the tip of the base.
Next, place an exemplar of the specified dimension on the base, adjust it to within the range that can be measured by touching it to the tip, and set the indicator needle to 0 (zero).
Remove the dimensional exemplar and place the workpiece to be measured between the base and the measuring element. The indication of the needle at that time is the dimensional difference between the model and the workpiece, so the dimensions of the relevant part of the workpiece can be measured.
Principle of Dial Indicators
There are two types of dial indicators: the spindle type, in which a rod-shaped measuring element moves up and down in the longitudinal direction to indicate the dimensional difference, and the method using this principle, in which a rod-shaped measuring element moves back and forth in the inclined direction to indicate the dimensional difference.
The spindle type is the most common for measuring simple shapes. The measuring element moves up and down, so it is relatively easy to adjust and fix it so that it is perpendicular to the base.
The lever type is often used to measure narrow areas where the measuring element cannot fit in the spindle type. Care must be taken in its use. The measuring element has a structure that tilts around its base. The measuring element must be installed at an angle close to a right angle to the direction in which the workpiece dimensions increase or decrease at the measurement position.
In both cases, the measuring element moves up and down or back and forth, causing the hand to swing like a clock. The difference from the model can be seen by setting the specified dimension to 0 (zero) on the model and reading the needle display while the workpiece is set to be measured. Particular attention should be paid to the display's resolution (how many millimeters are in one scale) and the number of weeks the needle is in the air, which must be visually confirmed while measuring.
By working with a defined measurement method and temperature control, even one-thousandth of a millimeter can be measured with high accuracy.
