Among the different types of instrument for measurement ( durometer , tape measure , dosimeter ) we find the Digital Calibrator , which is usually widely used in the industrial field. With which it is possible to obtain length measurements with great accuracy.
History of the Digital Calibrator
With regard to the history of this instrument there is not much to say. As we can imagine from the beginning, this device was not a digital instrument, but an analog one. It should be borne in mind that its beginnings date back to the 6th century BC.
There are many models of this instrument that have been found in different parts of the world. For example, in ancient China , objects similar to the caliper were found. However, its use dates from the Greeks to the Romans.
Moving further to the present we can say that the Digital Calibrator made its appearance in 1982. This was due to the development of meteorological sciences . It should be noted that this is the study of measurement of magnitudes. Being the same one of the sciences that has advocated the most for the improvement and evolution of different measurement instruments, among them the Digital Calibrator.
What is the Digital Calibrator?
To begin we must know that the Digital Calibrator, also receives other names such as vernier calipers. Being a laboratory apparatus elaborated so that both the length and the internal and external diameters can be measured.
In fact, it has great accuracy when it comes to measuring lengths. We must remember that when we talk about lengths we refer to the straight extension of a body. Now the Digital Caliper has its method to measure lengths , which is to use a kind of ruler with measurements on its lower side, where we find both centimeters and millimeters.
At the top we can also find measurements, which are inches and fractions of inches . Another characteristic of this ruler is that it has clamps similar to keys, which allow you to measure exteriors or interiors.
It should be added that in general the classical capacitors, apart from the main “rule”, have two verniers . Being these auxiliary scales, with which this device has. These items can be found located at the top and bottom of the gauge.
As we mentioned the verniers are auxiliary scales . That is, they are basically the ones that divide the main rules. Thanks to this it is possible to make measurements with a much broader level of accuracy.
These verniers are not currently available on Digital Calipers. Because they were changed by screens and buttons, which allow you to control their configuration . Thanks to this quality, these devices are much more accurate when making a measurement.
Basically by not having the person who manipulates the Calibrator do calculations, since these are thrown by the instrument itself, to avoid errors in the measurement . That is, this is a process that is done automatically. Apart from this there is another advantage of the calibrator in its digital format and that is that it gives measurements on different scales.
The latter means that if we want to do medications, it is a scale of millimeters or inches, we can do them. In fact, all scales are available on this device, it only needs to be configured to work with the desired scale.
Digital Caliper Feature
One problem with Digital Calibrators is that they can be a bit confusing at first. Due to this we must know its characteristics and parts well to avoid being confused while doing our work.
This does not mean that it is a difficult instrument to manipulate . Only in the beginning it is important to know the Calibrator well to be able to manipulate them. After a couple of practices with this instrument, we will be able to use them without problems and without errors. In more detail we can say that the parts or characteristics of this instrument are;
Screen that allows us to know what the measurements are automatically.
Switches on the screen, which allow turning the Digital Calibrator on, off and changing the scale.
Rod that is located at the back, being a thin piece and is used to measure depths.
Lower and upper jaws, the first being used for measuring external parts of an object. While the second for the internal part of the objects.
Working screw with which we can fix the position of the clamp, when we have the object ready to measure.
To finish with the characteristics of this device, we can say that since it does not have verniers, this instrument is much easier to use. This is because we only have to locate the object that we want to measure, and use the parts of the clamp and the rod to measure the object.
What is the Digital Calibrator for?
This is a measuring device, which has great precision. However, we must bear in mind that due to its size, it can measure small lengths.
However, it is just as useful as it can measure internal and external lengths , as well as depth. The latter is due to the fact that this calibrator has a meter for this purpose.
We have been mentioning that this device has a great prediction. This being specifically one- fiftieth of a millimeter .
Where is the Digital Calibrator used?
Regarding the place where this instrument is most used, we have in the industrial sector . Where it can be used to create other calibrators. We must bear in mind that many of the parts used in this device and in many more are made with this instrument.
How does the Digital Calibrator work?
Turning to what would be the use of this device, we can say that it is not very difficult to use, as long as we know its characteristics. As we mentioned before, among its features we find three buttons, one to turn on and off, another “0” button that clears the previous measurements and restarts the equipment and a third button which does not allow you to choose without measuring in gauges or inches.
In the event that we want to measure outside, we must only place the piece between the largest jaw. After this, the results will appear automatically on the screen of the device.
On the other hand, when we go to measure the interior we must use the smallest caliper . In this case we must place the object to be measured between them. Until they reach the top and we will obtain the measurement.
Finally, when we want to measure the depth, we must use the needle or bar for measurements. Being the same in the right end of the caliper.
Types of Digital Calipers
In order to determine the different types of Calibrators that there are, we must take into account the precision it has when measuring a target . Keep in mind that this can range from a tenth of a millimeter to a fiftieth.
It is important to mention that there is also a difference depending on what needs to be measured. Like the size of it. When we know their precision and size, we can classify them into different types.
In the case of doing it by size we have that the turner type are the much larger. In fact, they are designed to know what the exact mediations are in the holes. Because of this, the oversized Digital Caliper has only the external measurement keys . It is important to mention that in this case we are talking about a type of gauge used in construction.
But we must bear in mind that in many cases these calipers are not as accurate as the smaller ones. But still they are very used.
To all this we must add that this instrument has other differences between classic and digital calibrators. As we can imagine the classics are those that depend on their verniers. To determine the measure of an object accurately. In this case we find two types of calibrators, the universal ones and the ones with a clock. The latter being the ones that allow the easiest reading and can measure in inches without problems.
However, if we compare each of them, we can say that the Digital Calibrator has greater precision.
Importance of the Digital Caliper
The importance of this instrument lies in its precision when measuring an object. On the other hand, we can say that it is an object with a variety of advantages , among which the most important are the ease of use and its precision.
Due to this, when buying it with its predecessors, we can say without fear of being wrong that this is the one with the most precision and therefore the most used. In fact, some models have USB ports. With which we can measure and extract the measurement data , for later use.
However, we must add that the main drawback of this device is its high cost, which is above the classic models. However, it remains an indispensable calibrator for many areas of the industry.
