What is Screw Gauge?
A screw gauge is an instrument that accurately measures small lengths and diameters. The balance is comprised of a calibrated screw and a scale. Fine threads, one turn, and a short distance. Turning the screw causes movement of the measuring spindle against or away from the reference surface that stays put. The screw gauge has a scale from which one can take readings. This is an exact measure of an object being studied.
It consists of two scales: The pitch Scale and the Circle Scale.
- Pitch Scale: Pitch scale determines how far does the screw move in one turn. It assists in making sure that actual determination is done by tracking the screw movement and its turns.
- Circle Scale: A numerical scale that runs along the periphery of the screw is known as the circular scale. It’s just like a ruler but in a circular shape.
Total Reading = Pitch Scale Reading + Circular Scale Reading × least count of the gauge
Screw Gauge: Definition, Working Principle, Formula
Screw Gauge is an amazing device used for measuring small objects precisely. It is defined as an instrument that is used for measuring very small lengths, i.e. diameter of thin wires, the thickness of small sheets, papers, etc.
