Buying Guide of Best Dial Gauges
Dial indicators are some of the precise tools out there. Based on their accurate information, a lot of designs are done, and decisions are taken. So, buying a decent dial indicator that won’t flood you with the wrong information should be your main priority. To achieve this task, you should consider few factors that will help you while choosing the right one for you. Read below for the discussion,
Build
Dial indicators are very delicate tools and if they are too nimble, they will break easily. As these tools are mostly used in workshops, facing the rugged condition is a day in, day out. To withstand all those, the build of the tool should be robust. Therefore, look for those which are made from metal or stainless steel as they offer excellent integrity.
Accuracy
The more accurate the dial indicator is, the better results it will give – always keep this in mind. Look for those indicators which have the lowest margin of error. A low margin of error will assure you less proximity to get the false information. Most of the high-quality dial indicators come with an accuracy range of ±0.001 Inches.
Mounting System
Check whether it is lug back or flat back. Also, there are some which offer both. Lug back mounting systems are mostly recommended as they are more convenient to use and can offer more stability. Some also come with a magnetic stand which can provide additional ease.
Faceplate
No matter how the faceplate is, make sure you can understand the measurements easily. What’s the point of buying a dial indicator if you cannot understand what it says? Look for a bigger dial and clearer scaling for a better experience.
Case to Carry
Carrying the dial indicator is crucial. Carry wrongly and you will imbalance the calibration of the tool. Some manufacturers include a hard case with their dial indicator to minimize such occurrence, such as Clockwise Tools DICR-0105. Its hard case makes it very easy to carry it around safely and securely.
FAQ
How do you read a dial indicator?
Firstly, start with preparing your indicator. After that, measure your object. Make sure that you are extra cautious while measuring. Then look at the gauge. Specifically, the mode of operation entails marking the scale on the dial gauge’s body first and then determining the position of the dial gauge’s leading surface. Take the reading. Notice the highest line that is visible. If the measurement is in cm, convert to mm. Add both, and you will get your result.
What is the difference between a dial indicator and a test indicator?
Both the dial indicator as well as test indicator are precise measuring tools. However, differences are present, and they are quite distinct. The distinction is in the contact point. Test indicator is based on a lever, whereas dial indicators are based on plungers. Also, if you compare the size and weight, you will notice test indicators are fairly light and small. Because of their nature, both of them have their own distinct applications.
What are the two basic types of dial indicators?
The basic two types of dial indicators are lever type and plunger-type. The plunger-type dial indicator depends on a rack and a pinion. It calculates the change in the linear line and focuses on the movement of the pointer.
A lever-type dial indicator relies on a lever that scrolls to check the displacement. Here the lever has a limited movement. This type of good for inspection as well as to set up a machine.
What is the least count on a dial indicator?
The least count may vary depending on the type of dial indicator. However, the most standard least count is 0.01 mm, which has a range of 0.80-2 mm. If you get more specialized ones, you can even get the least count of very marginal significance. Here, we are talking about as subtle as 0.001mm, where the range is between 0-1 mm.
What should be avoided while using a dial indicator?
Dial indicators are very delicate, and they need extra care while using. Make sure the subject is not very harsh as it may damage the indicator. Also, oiling the spindle bearing is not a good idea. Better not to lock the indicator until it is properly under gauging tension. Tightening the contact points too away from the rack spindle will cause distortion, so better avoid doing that as well.
Final Verdict
To design and construct a precision part, calculating the measurement is crucial. In those situations, the need for a precision tool is inevitable. Dial indicators are one of those lifesavers which made precision counting way easier than before. You can even count the thousands of an inch, way out of our limitations.
To enhance your experience with precise part construction, get a good quality dial indicator. The market is bloated with a lot of dial indicators. However, not all are decent. You may also best dial indicators but sticking to the old school is more reliable. We tried to include all the best ones with their distinct offerings in our list of dial gauge indicators.
