Decoding The Depth Micrometer Measurement Dilemma: The What, Where, and Need of Calibration

The What


Depth micrometers deal with the precise measurement of small objects including the depth, width, and length of the items fitting within its anvil and spindle. These are excellent devices used for calibrating, training, and qualification of caliber gauge users. Depth micrometers have a base aligning with the top of the recess for carrying out depth measurements of different holes, recess, and slots. Depth micrometers offer more accuracy over vernier calipers as the latter has no absolute standard and can only be used for comparison purposes. With the least count of 0.01 mm and a measuring span of 25 mm, the span can be adjusted by upsetting the rod to fit the object under measurement.


The Where


Depth micrometer measurements are extensively carried out in machining applications. underwater diving and similar applications, and engineering instruments for measuring the depth of holes, and indentations from a reference point of the surface. For conducting measurements, you hold the device in your dominant hand, grasp the thimble between the thumb and index fingers, place the C-shape frame against your palm, and wrap your pinky or ring finger around the inside of the frame. This tool can deftly measure the depths of holes, slots, projections, and shoulders.


As much accuracy depth micrometers can offer, even these tools are prone to errors and mistakes that can only be made better with calibration. As professionals and engineers fail to get the best depth micrometer calibration, inaccurate readings tend to impact the quality of the design of manufacturing parts, equipment, and other tools that further impact businesses using those parts for production, processing, and other business flow verticals.


Why Calibration?


This section explains the importance of calibration to conduct depth micrometer measurements. Regardless of the brand and quality of the tool, if you cannot avoid these mistakes, the entire process of conducting measurement will be futile:


➔ Scale misreading or parallax effect

➔ Jaw tilt due to excessive force

➔ Thermal expansion due to temperature difference between caliper and workpiece

➔ Inside jaw-offset resulting in small hole diameter error


All in all, errors can arise due to different negligent tendencies. However, some of the common ones include eros in measuring the squareness of the tip to the micrometer base, lead errors, drunkenness, and over tightening of the screw. Calibration helps overcome all these errors by checking the accuracy of the instrument and determining the traceability of the measurement. Besides, with constant usage, the accuracy of measuring devices tends to decrease over time. It can be due to normal wear and tear, an electric or mechanical shock, a hazardous manufacturing environment like in the presence of oil, metallic chips, etc.


The hidden costs through an uncalibrated device tend to way more than getting it professionally done. An experienced and reputable company can save your time, efforts, and money resulting from your depth micrometer measurements with regular calibrations to minimize eros and keep the readings in an acceptable range.
