What is the depth shown on a depth gauge

The depth shown by a depth gauge is the vertical distance of an object or surface relative to a horizontal reference plane. Depth gauge is a measuring tool mainly used to measure the depth of workpieces such as holes, slots, bumps and depressions, etc. Its principle utilizes the measuring principle of a mechanical gauge. When the probe of the depth gauge comes into contact with the measured workpiece, the reading mechanism converts the movement of the gauge needle into a depth value, which is displayed on the dial.

Depth gauges are usually displayed in millimeters or inches. Depth gauges have a wide range of applications and are widely used in manufacturing, machine building, automotive maintenance, aerospace and other fields. Its accuracy and measuring range also vary with different brands and models. Generally speaking, the measuring accuracy of depth gauge can reach 0.01 millimeter, and the measuring range can reach several hundred millimeters.

In the process of practical application, the precision and stability of the depth gauge has a crucial role in the accuracy of the measurement results. Therefore, when using the depth gauge, you need to pay attention to keep the probe perpendicular to the measured workpiece, avoid collision or fall and other situations, so as not to affect the measurement results. At the same time, the depth gauge needs to be calibrated and maintained regularly to ensure its measurement accuracy and stability.
