Study Notes
Vernier Caliper
A Vernier caliper is a precision measuring instrument used to measure internal and external dimensions of objects.
Main Components
- Main scale: A linear scale marked with equally spaced divisions, usually in inches or millimeters.
- Vernier scale: A shorter, movable scale that slides along the main scale, with its own set of markings.
- Jaw: The movable part that is used to measure the object.
How it Works
- The main scale is used to measure the whole units (e.g., inches or millimeters).
- The Vernier scale is used to measure the fractional units (e.g., 0.1 mm or 0.01 inch).
- The Vernier scale is slid along the main scale until the zero of the Vernier scale aligns with a marking on the main scale.
- The measurement is taken by reading the main scale value and adding the Vernier scale value.
Types of Vernier Calipers
- Standard Vernier caliper: Measures external and internal dimensions.
- Depth Vernier caliper: Measures the depth of holes and recesses.
- Height Vernier caliper: Measures the height of objects.
Advantages
- High accuracy and precision
- Can measure small dimensions
- Easy to use and read
Applications
- Engineering: Measuring parts and components.
- Science: Measuring specimens and objects in biology, physics, and chemistry.
- Quality control: Inspecting products and materials.
