Dial indicators are mechanical instruments used to measure small distances, typically in the range of a few millimeters or less. They consist of a needle that moves across a graduated scale in response to changes in position. They are commonly used in manufacturing and engineering applications requiring precision measurements.
How Does a Dial Indicator Work?
The needle on a dial indicator is typically attached to a spring-loaded plunger, which moves in and out as the instrument is adjusted. This movement is translated into a corresponding needle action across the scale, allowing the user to make accurate measurements.
Choosing the Best Dial Indicators:
The best dial indicator for you will depend on your specific application and budget. However, when choosing the best dial indicators, consider the following factors:
- Accuracy – The accuracy of a dial indicator is the most crucial factor to consider. The accuracy is usually measured in thousandths of an inch or millimeters; look for a dial indicator with a high accuracy level.
- Durability – Ascertain a dial indicator’s durability made from high-quality materials and sturdy design.
- Resolution – The resolution of the dial indicator is the smallest measurement that the indicator can display. Consider a dial indicator that has a high resolution, especially if you need to measure small distances.
- Range – Choose a dial indicator with a range suitable for your specific application.
- Brand reputation – The reputation of the brand is also essential. Choose a dial indicator from a reputable brand with a good track record for producing high-quality products.
- Price – The price of the dial indicator is also a factor to consider. Look for a dial indicator that offers good value for money and fits within your budget.
What are the Uses of Dial Indicators?
Dial indicators can be used to measure a variety of parameters, including distance, height, depth, and runout, and are often used in conjunction with other measurement tools, such as micrometers and callipers, to provide more comprehensive measurements. They are available in various sizes and accuracies to suit different applications and are a valuable tool for anyone involved in precision measurement and machining.
