Pros and cons of digital calipers

You are an engineer, a scientist, or a physics teacher. You are struggling to know how to choose the best digital caliper and best suited for your work. Understanding the general psychology of everyone, in today’s article, I will introduce to you the pros of electronic calipers. Besides these advantages, every digital caliper has some common drawbacks, so depending on the pros and cons of the electronic calipers, you can consider and choose the best digital calipers suitable for your work.

The benefits of digital calipers

If the pros of the mechanical calipers are moderate price, durable design, the electronic calipers have many other outstanding benefits:

  • Easy to read results

With a mechanical caliper, you have to calculate complexly with measurements. However, the digital caliper appears to have “broken” that barrier. It is equipped with an LCD screen that makes it easy to see and read the results.

  • High precision

One of the advantages that cannot ignore when talking about electronic calipers is that they bring reliability and high accuracy. Some types of digital calipers can measure distances exactly like a micrometer to 0.001mm / 0.00004 inches.

  • Maybe 0 at any point

Digital calipers can be zero at any point without any recalibration. The zero function allows the user to calculate the difference between measurements automatically.

  • Measurements are easily converted

Distance measurement units can be changed instantly by pressing the mm / inch button.

The results can also be converted after we make the measurement. It helps ensure the reliability of the measurements, as manual conversion can sometimes lead to erroneous conclusions.

  • Diverse measurement features

Electronic calipers can perform up to four different types of sizes: measuring outside diameter, measuring inside diameter, measuring depth, and thickness.

  • The battery is quite good

Although it requires a battery to operate, it lasts quite a long time. Some energy-efficient calipers can work continuously for 3-5 years (20,000 hours) to replace batteries.

  • Shockproof

The digital calipers or electronic calipers are more shock resistant than other calipers because they do not have any moving parts (unlike the calipers with mounting mechanisms and gears). This means it is unlikely to be damaged if dropped.

Some drawbacks of digital calipers

Besides the advantages or the benefits, the digital calipers also encounter some limitations, and you need to pay attention to ensure the life of the device:

  • Water-resistant

Electronic calipers may be sensitive to water or coolants. However, some models are designed for use in harsh environments, which are resistant to dust and water.

  • Unreliable in hot or cold conditions

The digital calipers’ devices and components may be affected by very hot or cold conditions. It reduces the accuracy of the measurements.

  • Batteries required

Most digital calipers use batteries on-demand, making it challenging to find the right type on the market.

There are electronic calipers with spare batteries inside, but these models tend to be more expensive than standard battery-powered calipers.

Despite some small disadvantages, the digital caliper is still appreciated and is a reliable device to perform many different measurement functions.

Application

Depending on the pros and cons of digital calipers, we use them for different jobs.

  • In the steel industry

The calipers provide precise measurements in the steel industry, measuring the internal dimensions of steel objects or accurately measuring the thickness of desired objects that may have different shapes in the industry. The electronic vernier caliper also comes in handy when measuring the depth of holes in an object made of steel or metal. Also, it can measure the diameter of different cylindrical objects in steel pipes. To accurately measure the details of steel or metal materials, it is required that in addition to the accuracy of the caliper, the measuring technician must have a measurement technique to achieve high results.

  • In the automotive industry

Digital calipers can also be used for flexible measurement in the automotive sector, the calipers commonly used in this industry are those with sizes of 0 – 6 inches, although these calipers are not as accurate as micrometers. However, it still used quite popular in the automobile industry. The digital caliper is used to measure inside and outside diameters, to measure the width of the crankshaft, cylinder diameter, and height of springs.

  • In the science lab

Digital calipers are used for many different purposes in a science lab. For example, the study of the effect of temperature changes the size of the metal, you measure the size of the object when conducting experiments in two different parts. Besides, the vernier can measure regularly and irregularly morphological objects from inside and outside. Specially, you can measure the size of metal when there is a change in temperature so that it can analyze its properties and materials.

  • For education

It is commonly used in physics at all levels of the school. For instance, the distance of the caliper is used to teach students how to measure and get accurate measurements for an object, or correct the error setting the original value “0” for the ruler. Moreover, it is used in school laboratories to measure the internal and external dimensions of a geometric object or an object.

In short, digital calipers are used in many industries for measuring inside diameter, outside diameter, depth, and length of the object. Also, it can measure any part of the subject in any industry. With such importance, the selection of the best digital calipers from reputable brands is essential.
