Dial indicators are precision measuring tools commonly used in manufacturing and mechanical engineering applications. They are designed to measure small distances and variations with high accuracy, and are typically used to check the alignment of machine parts, the flatness of surfaces, or the runout of rotating components. Dial indicators feature a small dial face that displays the measured value in thousandths of an inch or millimeters, and a needle that moves in response to changes in position. They are available in a variety of styles and sizes, and can be mounted on magnetic bases or other fixtures for added convenience.

Frequently Asked Questions (FAQs)
1. What is a dial indicator used for?
Dial indicators, including dial test indicators, are used for precise measurements and comparisons of workpiece surfaces, machine components, part tolerances, alignment, and deviations from expected standards. They help ensure accuracy and precision in various industries and applications.
2. What are the 2 types of dial indicators?
The two types of dial indicators are lever dial test indicators and plunger dial indicators. Lever dial test indicators have an arm that sweeps an angle and measures lateral movement, while plunger dial indicators have a plunger that measures vertical displacement.
3. What is the difference between a dial test indicator and a dial indicator?
The main difference between a dial test indicator and a dial indicator is the way they measure. A dial indicator uses a plunger to measure how far it is raised by the surface below, while a dial test indicator uses an arm that sweeps an angle and measures lateral movement. Both types are useful, but the dial test indicator is often used more frequently.
4. What is the difference between a test indicator and a dial indicator?
Test indicators and dial indicators have some noticeable differences. Test indicators have lever-type contacts, while dial indicators have plunger-type contacts. Additionally, test indicators are smaller and lighter compared to dial indicators. These differences make test indicators more suitable for certain applications where size and contact type are important factors.
