Dial Calipers
Dial calipers are precision measuring tools used to measure inside, outside, and depth dimensions. They are typically made of steel or aluminum and have a hardened steel anvil and a hardened steel spindle. The anvil is the fixed jaw of the caliper, and the spindle is the movable jaw. The distance between the anvil and the spindle is measured by a dial indicator, which is a small, circular gauge with a pointer that moves along a graduated scale.
Dial calipers are used by a variety of professionals, including automotive mechanics, machinists, and surveyors. They are an essential tool for any job that requires accurate measurements.
Types of Dial Calipers
There are three main types of dial calipers: analog, digital, and vernier.
- Analog dial calipers have a mechanical dial indicator that moves along a graduated scale. They are the most basic type of dial caliper and are typically the least expensive.
- Digital dial calipers have a digital display that shows the measurement. They are more accurate than analog dial calipers and are easier to read.
- Vernier dial calipers have a vernier scale that allows for more precise measurements than analog or digital dial calipers.
Uses of Dial Calipers
Dial calipers are used to measure a variety of dimensions, including:
- Inside dimensions, such as the diameter of a hole or the width of a slot
- Outside dimensions, such as the length of a bar or the diameter of a rod
- Depth dimensions, such as the depth of a hole or the thickness of a plate
Dial calipers are an essential tool for any job that requires accurate measurements. They are easy to use and provide accurate results.
