Types of calipers
Calipers are used to accurately measure manufactured parts or anything we want to measure. Different types of calipers are classified according to their appearance, application (such as altimeter caliper, depth gauge caliper, groove caliper, radius caliper, etc.), ten units of measurement or measuring systems (such as metric and inch systems). Which include:
Varnished calipers (with varnish)
Clock Calipers
Digital Calipers
In the following article, we will give a brief description of all vernier calipers, clock calipers, digital calipers and their types, and ask questions such as, what is the quantity of calipers? In what jobs is the caliper used? And? Dear reader, after reading this article, you can name the components of the caliper, know the types of calipers in terms of accuracy, master the reading of the caliper and the components of the caliper, and answer the sample questions of different calipers and easily You can get the price of caliper with good searches.
Vernier calipers
Vernier calipers come in different types, such as ordinary vernier calipers, altimeter caliper, veneer caliper, depth gauge, and so on. Also, in terms of measurement system, we can name millimeter and inch calipers. To get acquainted with how to read different types of millimeter calipers, in terms of measurement accuracy, click here, and to get acquainted with how to read different types of inch calipers, For more information, click here. In the following article, we will give a complete knowledge of different types of vernier calipers, along with their application.
Ordinary Vernier Caliper
Ordinary millimeter and inch vernier calipers are common tools and instruments of technical works and industrial and production factories for internal and external measurements of parts and products. Of course, for the production of series and mass work, measuring systems and equipment should be used that are easy and fast to use and do not require much accuracy compared to the time of production. For example, choosing different measuring gauges (hole gauges, mouth torpedoes, grooves, etc.), digital calipers or watches is a good choice for this task, which will be discussed in detail below. The figure below shows the internal and external measurements and the rotation of the caliper forks inside the workpiece to test the complete circle and the absence of machine defects during production.
Vernier height gauge caliper
Vernier caliper is used to measure the height of the parts.
Vernier caliper calipers are composed of different parts, just like ordinary vernier calipers. The first part that is seen in this type of caliper and is used to move this part is its base, which is usually made hollow to make the final product lighter and cheaper. In this case, both the final payment of the product will be easier in terms of construction and the level of reliance will be reduced and it will not stick to the stone or metal table (flat plate). To move the altimeter calipers, it is better to take it from the base, lift it and move it.
Other parts of Vernier altimeter calipers are:
Types of connection screws, loose and sliding adjustment
It has a ruler with inch and millimeter divisions
Measuring prongs, usually made of resistant materials to prevent abrasion.
It has an interface nut between the sliding slider and the mechanism for low displacement. In this case, to use this part, tighten the lock screw of this mechanism and loosen the sliding screw.
Digital or electronic caliper
As is clear from the name of this type of calipers, their operating system is electronic and they are sensitive to change of size and are generally more vulnerable and vulnerable than Vernier calipers and clock calipers. The accuracy of these calipers is 0.01 mm and 0.001 inch.
Different parts of digital or electronic calipers
The various parts of a digital or electronic caliper are generally similar to Vernier calipers and clock calipers, and are different:
Has a number display
On / Off key (ON / OFF)
Measuring system switch (inch / mm)
ZERO key
HOLD KEY
The difference between a vernier caliper, a clock caliper and a digital caliper
The main difference between vernier calipers, clock calipers and digital calipers in the measurement system is that in vernier calipers and digital calipers, by buying a caliper, we also have a millimeter system. Also the inch system (depending on the brand, but most have which we can choose when buying). But in hourly calipers, we have to prepare millimeters and inches separately.
Appearance difference between varnish caliper, clockwise caliper and digital caliper
Another important difference is that, in all vernier calipers, clock and digital calipers, such as ordinary vernier calipers, altimeter calipers and depth gauge calipers, which have been discussed in detail, may not have the same components and generally have different designs and With different components.
Differences in reading Vernier Caliper, Clock Caliper and Digital Caliper
In terms of reading vernier calipers, clock calipers and digital calipers and in general all types of calipers are the same in the metric and inch system, which are discussed in detail in the articles mentioned above, with practical examples in separate articles. That you can read.
