What does depth gauge mean?
What does depth gauge mean?
: a gauge for measuring the depth of holes, grooves, or concavities.
What is a vernier depth gauge?
What is Vernier depth gauge? Vernier Depth Gauge as the name suggests is used to measure the depth from the surface of reference of an object. Vernier caliper also has depth bar but this can not be used as the standard measurement.
What is the purpose of depth gauge?
A depth gauge is an instrument for measuring depth below a reference surface. They include depth gauges for underwater diving and similar applications, and engineering instruments used to measure the depth of holes and indentations from a reference surface.
How do you use a vernier depth gauge?
How to measure depth using a vernier caliper?
- Step 1 – Turn thumb screw to extend depth rod. Move the thumb screw gradually until the end of the end of the beam scale makes contact with the top of the hole.
- Step 2 – Position rod in hole.
- Step 3 – Turn Lock Screw.
- Step 4 – Read Measured Value.
How do you use a deep gauge?
Place the depth base on a surface plate or flat surface. Loosen the bezel lock screw, adjust the dial on the depth gauge to the “0” position and tighten the screw. Zeroing the indicator (without the extensions) on a flat surface.
What tools are measuring hole depth?
Depth Measurement. The depth micrometer is an accurate and reliable tool to use for depth measurement (Figure 1). The depths of holes, slots, shoulders, and projections can be measured accurately to within 0.001 of an inch. When using a depth micrometer, two points must be kept in mind.
What is the principle of height gauge?
A height gage is a measuring instrument in which a slider with a measuring stylus moves relative to a measuring scale on a beam and in which this motion is along a single vertical axis nominally perpendicular to a reference plane on the instrument base.
What is the purpose of a vernier depth gauge?
Vernier depth gauge is used for measuring the depth of holes, recesses and distances from a plane surface to a projection. Here the graduated scale is slide through the base and vernier scale remains fixed. Running through the depth gauge body is the main scale the end of which provides the datum surface from which measurements are taken.
Where is the measuring tip on a vernier scale?
The sliding jaw runs on the main scale with the guiding surface, which is accompanied by a vernier scale, in which it has a measuring tip on the left side. When two measuring tip surfaces are in contact with each other, the scale shows zero reading. The finer adjustment of the movable jaw can be done by adjusting screw.
How does a Starrett vernier depth Gage work?
Readings are taken directly from the rack and the dial indicator. Large openings can be measured using an extension base. Starrett Vernier Depth Gages are available in either a 6″ or 12″ (150mm or 300mm) range and are a quick and accurate method of measuring depth of holes, slots and recesses. directly from the rack and the dial indicator.
What are the jaws of a vernier caliper used for?
A Vernier caliper has main jaws that are used for measuring external diameter, as well as smaller jaws that are used for measuring the internal diameter of objects. Some models also have a depth gauge. The main scale is fixed in place, while the Vernier scale is the name for the sliding scale that opens and closes the jaws. 2
