What Is a Digital Micrometer?
A digital micrometer is a type of micrometer used for measurements that require high-dimensional accuracy in the order of 1 micron.
Since the measured dimensions can be checked visually and instantly, it is actively used at manufacturing sites. It helps prevent misreading of the scale, as is the case with analog micrometers that directly read the scale.
The components are basically the same as those of the analog type, and the digital type is also inscribed with a scale.
Uses of Digital Micrometers
Micrometers are mainly used at manufacturing sites and for measuring parts that require high dimensional accuracy in units of 0.001mm. They are capable of even more precise measurements than calipers.
In addition, various types of micrometers are available for different applications. These applications range from basic O.D., I.D., and depth measurements to measuring the tooth thickness of spur gears and measuring narrow grooves. They can even measure the web diameter of drills. Micrometers are widely used in a variety of situations and for a wide range of applications.
Features of Digital Micrometers
The construction of digital micrometers is basically the same as that of analog micrometers. However, since they are digital, they have a power button, a button to set the zero point, and a button to hold the measurement.
Some digital micrometers are also equipped with a function that allows measurement results to be transferred to a PC or tablet, which contributes to the efficiency of operations.
However, since digitally represented dimensions may be misrepresented due to electrical problems, and incorrect values may be displayed, they are only for reference purposes and must ultimately be checked directly on the scale to confirm that the dimensions are correct.
In addition, since direct contact with the micrometer will cause the frame to warm up with body heat, making accurate measurement impossible, a micrometer stand must be used to hold the micrometer in place for measurement.
Furthermore, since it uses batteries, the risk of the batteries running out is a disadvantage.
