about caliper and its types
Calipers can be called the right hand of engineers in various industries. Measurement accuracy has always been one of the most important topics in engineering, and in countries with advanced industries, we see more accurate measurement equipment. Calipers have long been used by engineers as a high-precision measuring tool.
The history of calipers
According to recorded studies, the first use of the Caliper is related to Romans and Ionians. But the oldest caliper dates back to the 6th century BC and was found in the ruins of an island off the coast of Italy. The wooden part found has a fixed part and a movable opening. Modern calipers were invented by Pierre Vernier, who was a French mathematician and inventor.
Types of calipers
Like many other tools, calipers are produced in different types. Calipers have 3 common models. Vernier caliper (simple), dial caliper (hourly), digital caliper. All these calipers are very similar in terms of performance. Only reading values in these calipers differ from each other. All these calipers include a ruler with a fixed opening and a moving opening with an indicator.
- Vernier caliper (simple)
- Caliper (hourly)
- Digital caliper
Vernier caliper
A simple caliper has a fixed ruler (in centimeters, millimeters, and inches) and a moving part (called a vernier).
Dial caliper
Dial calipers use a dial to accurately help you read a workpiece or tool in fractions of a millimeter or inch.
Digital caliper
A digital caliper is a precision instrument used to take very accurate measurements. The caliper is easy to use with a digital display. Most are able to measure up to 0.01 mm (0.0005 inches).
