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 measurement  even when they are too small. The Dial Indicators can be used as Comparotors Basically, comparators are the precession measuring instruments used to compare the workpiece measurements with the standard measurements. When this Dial Indicator is used in any measuring equipment for comparison purpose then these equipment are called  Dial Gauges. A Dial Indicator must be mounted on any other base/Equipment, otherwise, it will be useless.  The accuracy of the dial indicator is up to 0.001 mm are available. Construction of Dial Indicators There is a classification of dial indicators based on their dial shape. They are sector shape Dial Indicator and Circular shape Dial Indicator. But sector type is a quite limited range, so this sector type Dial Indicator is used for extremely accurate measuremen...

What is a vernier caliper? How to use?

Instructions on use The Vernier caliper is an extremely precise measuring instrument; the reading error is 1/20 mm = 0.05 mm. Close the jaws  lightly  on the object to be measured. If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord. Ignore the top scale, which is calibrated in inches. Use the bottom scale, which is in metric units. Notice that there is a fixed scale and a sliding scale. The boldface numbers on the fixed scale are centimeters. The tick marks on the fixed scale between the boldface numbers are millimeters. There are ten tick marks on the sliding scale. The left-most tick mark on the sliding scale will let you read from the fixed scale the number of whole millimeters that the jaws are opened. In the example above, the leftmost tick mark on the sliding scale is betwee...

RRB JE METROLOGY FULL DETAIL SYLLABUS EXPLANATION

What is the linear measurement and Types of linear measuring instruments. There are a wide variety of geometries that are measured in angular units. These varieties include angular separation of bounding planes, digression from a basic direction, angular spacing conditions related to a circle, etc. Because of these diverse geometrical forms, different types of methods, equipment and instruments are available to measure angles in common angular units of degree, minute and second. Several factors come into the role in the selection of appropriate angular measuring instrument. These factors may be the size, general shape of the part, the location and angular accessibility of the feature to be measured, expected a range of accuracy, etc. As in linear measurement, they can be categorized into two groups. The first one is standard line instrument. It includes divided scales like protractors, Bevel Protractors. The second category of angular measuring instrum...
