Scale Dials, also known as Vernier or micrometer scales, are a type of measuring instrument used in various industries to accurately and precisely measure distances. The scale dial is composed of two parts – one is a fixed scale, and the other is a movable dial with a magnifying glass. The scale is calibrated to produce the same divisions on both the fixed scale and the dial, so that when the two scales are placed together, the magnified divisions are visible through the magnifying glass. The scale divisions can be measured to either tenths, hundredths or thousandths of a millimetre, hence measuring devices with measurement accuracy to 1µm or less can be used.
The 28A11B10 Scale Dial is a kind of micrometer scale used to measure distances with an accuracy of 0.1µm. It is a mechanical device consisting of a fixed frame made of stainless steel and an adjustable moveable scale. The scale acts as a guideline when measuring distances in order to obtain measurements with very high accuracy and precision. This type of scale dial is ideal for applications in the automotive, pharmaceutical and electrical industries. For instance, it can be used to accurately measure the distance between two components in a car, or to measure the thickness of a tablet in the pharmaceutical industry.
The working principle behind the 28A11B10 Scale Dial is fairly simple. The fixed frame is used as a standard to measure against and the adjustable movable scale can be moved to the desired measurement point. The adjustable scale has grooves on either side which can be matched up with the grooves in the fixed frame when the desired distance is reached. A magnifying glass is then used to measure the exact measurement by reading the scale divisions. The magnified scale can then be read to calculate the exact distance or thickness in either tenths, hundredths or thousandths of a millimetre, depending on the accuracy of the scale.
In summary, the 28A11B10 Scale Dial is a precision measuring tool designed to measure distances accurately and precisely to 0.1µm. It is typically used in the automotive, pharmaceutical and electrical industries to measure the distances between components and the thickness of tablets. The working principle behind the scale dial is quite simple as it relies on the grooves of the scale to provide an accurate measurement in either tenths, hundredths or thousandths of a millimetre. This makes it a very useful and precise measuring tool for different applications.
