Metrology Glossary: Caliper
What Is a Caliper?
A caliper is a precision measuring tool used to gauge the thickness, width, diameter, or depth of an item. It consists of two adjustable legs or jaws that can be closed to secure the object under measurement. These jaws are usually crafted from hardened steel, ensuring accuracy. Calipers find applications across various sectors such as manufacturing, engineering, and construction.
Where Are Calipers Used?
Calipers find extensive application in multiple industries including:
- Manufacturing: Calipers are used to gauge the dimensions of a diverse range of components, from minute parts to extensive assemblies. For example, calipers are used to assess the diameter of a shaft, the thickness of a metal sheet, or the depth of a bored hole
- Engineering: Engineers utilize calipers in the design and testing phases of product development. Calipers are used in measuring the dimensions of prototypes, ensuring that products adhere to specified criteria, and diagnosing any issues. For example, an engineer might use a caliper to measure the thickness of an airplane wing, verifying its strength to withstand the stresses of flight.
- Construction: Calipers are used to measure the dimensions of various building materials, such as lumber, drywall, and concrete. Their role is to guarantee that materials conform to the correct size and shape before installation. For example, a carpenter might use a caliper to measure the thickness of a piece of lumber, ensuring it aligns with the project’s required specifications.
