What is vernier caliper and its uses?
A vernier caliper is a device that is used to calculate very accurate linear measurements. A vernier caliper is also used to measure the diameter of round and cylindrical objects, by positioning the jaws of the caliper on either side of circumference.
What is vernier caliper simple definition?
A measuring instrument consisting of an L-shaped frame with a linear scale along its longer arm and an L-shaped sliding attachment with a vernier scale, used to read directly the dimension of an object represented by the separation between the inner or outer edges of the two shorter arms.
What does a vernier calipers measure?
Figure 3 shows a common use for a vernier called a vernier caliper. This caliper can measure the outside diameter of an object (outside vernier), the inside diameter of a hole (inside caliper), or the depth of a hole (depth probe).
What is called vernier caliper?
The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale.
What are the parts of vernier caliper and their functions?
Vernier Caliper Functions & Important Parts Lower Jaws: The upper jaws are the most prominent feature of a vernier caliper. Upper Jaws: The upper jaws are smaller in size and are attached to the upper portion of the vernier caliper. Depth Rod: The depth rod is another useful feature of the vernier caliper which can be used to measure the depths of holes or steps.
Is a vernier caliper more accurate than a micrometer?
A micrometer always stays more accurate than the Vernier caliper because of the mode through which the values get calculated. The primary tools used for the calculation for a Vernier caliper become a sliding Vernier scale to measure small changes. On the other hand, a small screw comes in handy when we calculate the readings on a micrometer.
Why is a vernier caliper used to measure length?
Although a common and easy method of measuring the length of a cylinder or any object is to use the metre rule but in many situations more accuracy and precision may be required. In such situations the use of a vernier caliper helps to overcome the shortcomings of the metre rule and provide a better way to measure the length.
What is the difference between micrometer and vernier caliper?
Vernier calipers (vernier callipers) and Micrometers (Micrometer screw gauges) are both used to measure distances too small to be measured using a metre rule with a least count of 1 mm. The main difference between vernier caliper and micrometer is that the vernier caliper uses two sliding scales with different spacings between markings on each scale while a micrometer makes use of a screw to translate small distances moved by its jaws to larger distances along the marked scale.
