How does a dial gauge work?

The working principle of the Dial Indicators is that the movement of the spindle multiplied with the reading of the main scale due to the indication of the needle. In addition to this, at the main scale rotation of pinions and gears is indicated. The plunger which meshes with P1 and G1.

What does dial gauge mean?

Definition of dial gauge : a gauge consisting of a circular graduated dial and a pointer actuated by a member that contacts with the part being calibrated.

What is the type of dial gauge?

A single reading of a standard-type dial gauge is 0.01 mm, but there are also special dial gauges with a single reading of 0.001 mm. In addition to an analog type where measurements are read on a scale, a digital type is available as well.

Where are dial gauges used?

Dial indicators are one of the primary measuring tools used in precision engine building. They are typically used to measure deck clearances, crankshaft thrust and straightness, lifter travel and other measurements that involve the distance between two surfaces or small amounts of component travel.

How accurate is a dial gauge?

Dial Thickness gauge has an accuracy of 0.01 mm.

What is a problem in using dial gauges?

When used for measuring amplitudes of vibration, the dial gauge was found to have two major errors, one occurring at low frequencies, the other appearing at high frequencies. The low frequency error is caused by the weakness of the hairspring which takes up backlash in the mechanism.

How do you zero a dial gauge?

Next, the dial indicator must be zeroed. To do so, rotate the outer dial bezel and position the gauge zero mark directly on (over) the large needle, regardless of where it’s pointing. Once the dial indicator is zeroed, you can take measurements by moving the target part through its range of travel.

What are the 3 parts of measurement?

So a measured number has 3 parts; magnitude, unit and entity.

What is the practical use of a dial gauge?

Size of the dial gauge is very small and compact,so it can be used easily in mass production.

Dial Gauge used for the Quality Departments and tool rooms for acceptance of the tools or components. So, these are the dial gauge application in the mechanical field; in addition to these, the dial gauge is used for testing the roughness of the surfaces.

What does a dial gauge measure?

A dial gauge is a precision measurement commonly used to measure machined parts for production tolerances or wear. Dial gauges are capable of producing extremely fine measurement values; increments of 0.00005 inch (0.001mm) may be possible with some gauges. Measurement inputs are transferred to the gauge via a plunger,…

How do you set a dial bore Gage?

Based on the size bore you will be testing, set the micrometer. With extensions compulsory for the bore’s diameter, set up the dial bore gage. The bore gage is then placed between the anvil and spindle of the micrometer. Rock the gage side to side and back and forth in the micrometer. Zero the dial indicator to the minimum reading.
