FAQ

Can a dial indicator be used for both linear and angular measurements?

Yes, a dial indicator can be used for both linear and angular measurements. Dial indicators are devices used to measure linear dimensions, such as the run-out of a workpiece, with graduations of 0.001 mm to 0.01 mm (metric) or 0.00005in to 0.001in (imperial/customary).

They can also be used to measure angles and positions, such as center alignment and angle measurement.

However, it should be noted that while dial indicators can measure angles, they are not specifically designed for precise angular measurements.

For more accurate angular measurements, instruments such as protractors or goniometers are typically used.

What are the advantages of using a dial indicator?

Dial indicators have several advantages over other measurement tools:

Ease of use: Dial indicators are easy to use and do not require any special training.
Accuracy: Dial indicators are very accurate and can measure small distances with high precision.
Versatility: Dial indicators can be used for many different measurements by means of a few simple attachments, making them more versatile.
Speed: Dial indicators are fast and easy to read, which is useful for quality control in the inspection room.
Positive visibility: Dial indicators have positive visibility, which means that the readings are easy to see and interpret.
Economy: Dial indicators are relatively inexpensive compared to other measurement tools.

Overall, dial indicators are a quick, easy, and accurate way to measure distances with minimal effort.

What are the limitations of using a dial indicator?

There are several limitations and factors to keep in mind when using a dial indicator:

Not sensitive enough for time-based phenomena: Dial indicators are not sensitive enough to measure many time-based phenomena, such as magnetic measurements over a few milliseconds duration.
Loss of accuracy due to machine vibration: Dial indicators frequently lose accuracy due to machine vibration.
Parallax effect: The parallax effect is a major disadvantage of the instrument. Since the dial indicator is viewed from an angle, the user must be careful to avoid misreading the measurement due to the angle of view.
Special care and storage conditions: Dial indicators are extremely precise and delicate measuring devices that require special care and storage conditions to maintain accuracy.
Size limitations: The size of the dial indicator limits the person using it in space, which can be a disadvantage in some situations.
Specialized instruction and close monitoring: Dial operation calls for specialized instruction and close monitoring to ensure accurate measurements.

Despite these limitations, dial indicators are widely used in manufacturing facilities for their accuracy and reliability in measuring linear distances.

Can a dial indicator be used in conjunction with other measurement tools?

Yes, a dial indicator can be used in conjunction with other measurement tools for more precise measurements. Dial indicators are often used to take critical measurements or to check the tolerance of an item.

They can be used in combination with other measurement tools such as calipers and micrometers to provide more accurate measurements.

For example, a dial indicator can be used to measure the difference from the surface of one object to the other, around a hole or boss, while a caliper can be used to measure the distance between two points on an object.

Dial indicators can also be used with a variety of bases, such as magnetic bases, to hold the indicator in a fixed position and provide more accurate measurements.

What are the different types of dial indicators available?

There are several types of dial indicators available in the market, each with its own unique features and applications:
