sügavusmõõtja

A sügavusmõõtja, also known as a depth gauge, is a measuring instrument used to determine the depth of a cavity, hole, or the thickness of a material. These devices are employed in various fields, including manufacturing, machining, and metrology. The fundamental principle behind most depth gauges involves a reference surface and a movable probe or spindle that extends into the depth being measured.

There are several common types of sügavusmõõtja. Vernier depth gauges utilize a sliding scale and a main scale to provide precise readings, similar to a Vernier caliper. Digital depth gauges offer electronic readouts, often with high accuracy and ease of use. Dial depth gauges employ a dial indicator to display the measurement. Screw-type depth gauges use a calibrated screw mechanism to extend the probe.

The selection of a specific sügavusmõõtja depends on the required precision, the nature of the measurement, and the working environment. They are essential tools for ensuring that manufactured parts meet specific dimensional requirements and for quality control processes. Accurate depth measurements are critical in many engineering and manufacturing applications to guarantee proper assembly and functionality.
