6 Different Types Of Calipers & Their Functions               

Calipers are important measuring tools used in many industries, including manufacturing, engineering, automotive, and aerospace. They measure objects with high precision, both inside and out. There are many types of calipers, each with different features and benefits. It’s important to know what they do and where to use them. This article gives an overview of calipers. It explains their functions and uses in different industries.

Calipers Introduction

Calipers are tools used to measure the size of an object – its length, width, height, or diameter. These tools have two jaws that adjust to measure the size of an object accurately. Industries need precise measurements to make good products and work well. So they use calipers a lot. Technicians and engineers can ensure accurate measurements and high-quality standards by knowing different types of calipers and their functions.

  • Vernier Calipers

 Vernier calipers are common and have a main scale and a sliding vernier scale. The main scale measures in millimeters or inches. The vernier scale gives more precision for smaller measurements. The user places the jaws around or inside the object being measured. Then, they combine the main scale and vernier scale values to get the reading.

Vernier calipers are cheap and easy to use. They are favored in many industries. People use these to measure mechanical parts, inspect products and assure quality.

  • Dial Calipers

 Dial calipers look like vernier calipers but use a dial instead of a scale. The dial indicator shows the measurement directly. It’s easy to read and reduces errors. You can get dial calipers in metric or imperial units. They’re very accurate and precise.

Industries like aerospace, automotive, and manufacturing use dial calipers for precise measurements. They are often used to measure the size of mechanical parts, check finished products, and control quality.

  • Digital Calipers

 Digital calipers are a modern option to traditional vernier and dial calipers. They are also called electronic calipers. They have a digital display that shows the measurement directly. This removes the need for manual calculations and lowers the chance of errors. Digital calipers have added features. You can switch between metric and imperial units and zero-set them at any position. They also offer data output that lets you connect them to computers or other devices.

Industries like electronics, medical, and precision engineering use digital calipers for exact measurements. These calipers are becoming more popular. These tools measure small parts, inspect fragile components, and verify that quality standards are met.

  • Inside Calipers

Inside Calipersare made for measuring the inside of objects. For example, they can measure the size of holes, slots, or the space between two surfaces facing each other. They have bent or curved jaws which can adjust to fit inside the object being measured. This gives an accurate measurement of its internal size.

Many industries, like machining, metalworking, and woodworking, need to make precise measurements inside products. To ensure quality and efficiency, they use inside calipers.

  • Outside Calipers

Outside Calipers measure the outside of things like rods, flats, and plates. These devices have jaws that adjust to fit around the object you want to measure. This gives an accurate measurement of its size.

Industries like metalworking, woodworking, and manufacturing commonly use outside calipers. Accurate external measurements are crucial for maintaining product quality and process efficiency.

  • Divider Calipers

Divider calipers, also called compasses, mark distances and transfer measurements between objects. They have two sharp, pointed legs that can be moved to the desired distance. You can use them to draw lines or mark points on an object’s surface. Divider calipers are often used in industries like woodworking, metalworking, and drafting. They help ensure accurate marking and layout, which are important for quality and efficiency.
