Types of calipers

You are planning to purchase a caliper for your job. However, on the market today, there are many different types of calipers with diverse designs and many different characteristics and materials. It makes you extremely confused and does not know which one is the best and most suitable?

Understanding your thoughts, in today’s article, I am presenting some differences in calipers to keep in mind while choosing the best and the most suitable calipers for your career. Are you curious about what those differences are? I won’t make you wait any longer. Let’s find out what they are right now.

Along with micrometers, gauges, the vernier caliper is also an indispensable measuring device in the field of mechanics. First of all, maybe support users to check the status of the mechanical equipment they own after a period of use, or the parts are processed to ensure their accuracy. Calipers divide into three main types: mechanical calipers, digital calipers, meter calipers.

What is a caliper?

The vernier caliper is a versatile measuring device (external dimension, internal dimension, depth gauge) that widely use in the industry. It is composed of: inner measuring function, external measuring function, fixed function, dynamic function, locking pin, depth gauge and body ruler, mm / inch unit. As for accuracy, we have different types of calipers with unusual precision, such as 0.1 mm, 0.05 mm, 0.02 mm. Calipers classify into three main categories based on their characteristics and accuracy.

Mechanical calipers

This type of caliper displays results via automatic lines. Material made of stainless steel or alloy anti-abrasion, anti-fouling. Some examples of mechanical calipers, specifically for the food industry, are made of fiberglass. The caliper is going to distinguish based on scale and accuracy. If the same size and efficiency are different, they will differ in the type of mount. The jaw of the mechanical caliper will be of varying length and length; the unique mount has its design. Calipers with special mounts will dedicate to a particular measuring function, usually grooving. The mechanical vernier caliper will also distinguish the difference through a ruler brake or fine-tuning screw. Most mechanical calipers will brake or lock the ruler with screws. Some others will lock automatically with the push of a button – release the operating finger immediately. The depth gauge of the mechanical caliper, the most common of which is a flat grip. In some unusual situations where you need to measure the depth of a small, round hole, you should choose a cylindrical rod type. The depth gauge is just an extension of the mechanical grip, so the default is flat.

Electronic calipers or digital calipers


It is a handy caliper, accurately measuring the size of small objects. Users can easily view the results through the display on the electronic screen quickly. Regarding the battery supply for the calipers, most digital calipers use the same universal easy-to-find universal battery. There are some types of battery-powered rulers, but it’s not entirely necessary, so you don’t need to pay attention. Need to pay attention to the details of indicator screen with backlight or not? If used in environments with low or too bright light sources, circumstances with backlight (backlit = backlight = background light) should consider. High-grade, strong clamp, round workpiece, square workpiece, and basic geometric shapes. The tail gauge has a rectangular or rectangular depth gauge. Smart sensor technology (S.I.S.) = S.I.S. = Smart Inductive Sensor Automatic power off when long no effect. Automatically switches to standby to save battery. Digital calipers can set the ZERO position at any position. Conversion of measurement units mm / inch. Data after measurement with the calipers can transfer to a P.C. via USB or RS232 communication protocols.

With this type of caliper, users will observe the measurement results via the digital clock face on the caliper. The meter caliper has both metric and inch scales. The scale on the ruler is laser engraved. Most calipers have anti-shock features. Waterproof dew point type, meet IP40 standard. Standard of DIN 862. The depth gauge is like a regular mechanical caliper.

In conclusion

I have shown the differences you need to consider when selecting the best caliper for your job. I hope that this information I have provided for helping you. Besides considering the above factors, when buying, you need to know the brands of them and their characteristics to support your career. Lastly, thank you for taking the time to read through this article. I wish you to purchase the most suitable caliper.
