Dial Indicator | Dial Gauge | Types Of Dial Indicators | Working Principle
The Dial indicator is a mechanical mean, having gears and pinions or levers for magnification system. They can responses to linear measurements even when they are too small. The Dial Indicators can be used as comparators. Basically, comparators are the precession measuring instruments used to compare the workpiece measurements with the standard measurements. When this […]
Scalar and Vector | Definitions | Differences
In physics, Scalar and Vector are two distinct quantities of measurements. In this article, we are going to discuss the definitions with the examples. Scalar and Vector Definitions Scalar is a single dimension quantity whereas the Vector is a two-dimensional quantity. Scalar has a magnitude and vector will have both magnitude and direction. Make sense?…… No? …… […]
Micrometer Screw gauge, Working Principle, construction, Reading measurements
Topic: Micrometer, Working Principle, construction, Reading measurements. The Micrometer is known for screw gauge because a calibrated screw is used for precise measurements. The accuracy of the micrometre screw gauge is 0.01. This is very high accuracy compared to the vernier calliper accuracy 0.02. Most of the engineering works have to require more precession. so screw gauge is […]

What is Least count of an instrument?
In Metrology The least count of an instrument is the smallest change in the value that can be measured with the measuring instrument. Least count for Steel Ruler For example in a Steel Ruler, there are twenty divisions between each 10-millimetre scale reading. So the least count for this steel ruler is 0.5 millimetre. The formula for […]
