What is the difference between vernier caliper and Vernier height gauge?
Vernier Height gauge is used to measure heights. Vernier Height gauge is similar to vernier caliper, but the graduated scales are held vertically. and this Vernier height gauge used in conjunction with a surface plate.Dec 20, 2017
Who invented Vernier height gauge?
Pierre VernierAs long ago as 1631, Pierre Vernier, a French scientist, mathematician and engineer invented the “Vernier scale” and so provided the basis for mechanical engineers to measure and manufacture more accurately than ever before.Jul 27, 2018
What is the advantage of Vernier height gauge?
Advantages of Vernier Height Guage : It can be used in different ways: one set of jaws can be used to determine inner measurements, while the other set can be used to measure exterior measurements. It is the simplest and quickest of the vernier instruments to use, and it is also quite cheap.
How to use Vernier height gauge?
Procedure Of Using Vernier Height Gauge : 1. Take the material (sample) for which the value must be measured. 2. Check the vernier and the main scale must coincide at 0. 3. After checking the 0 marks put the sample piece and slowly leaves the measuring jaw over the piece.
What are Vernier height gauges made of?
The important features of vernier height gauge are : all the parts are made of good quality steel or stainless steel. The beam should be sufficiently rigid and square with the base. The measuring jaw should have clear protection from the edge of the beam at least equal to the projection of the base from the beam.
What is height gauge?
A height gauge is a measuring device used either for determining the height of something or for the repetitious marking of items. It is much more capable than calipers but not as complex as a coordinate measuring machine (CMM). Vernier height gauges, however, greatly rely on users’ skills.
What is the size of a Vernier gauge?
They are generally available in measuring size ranges from 6 inches to 6 feet. Models can have imperial (inch) or metric (mm) scales or both on them.
How does a height gauge work?
Height gauges consist of a sliding carriage with a moving stylus or scribe that is mounted to a vertical axis beam or column that contains a measuring scale. The beam is configured so that it is perpendicular to the base of the height gauge, which is typically made using a rigid material to add stability to the instrument for measurements. The beam or column height can vary from 6 inches or less to upwards of 6 feet, depending on the model. Custom gauges may extend the column height even higher. The carriage movement is controllable and may be adjusted by a set of adjustment screws for coarse or fine adjustments and may be locked into position as needed. A measuring jaw is used whose upper and lower surfaces are parallel to the base of the height gauge. In the case where it is desired to scribe the workpiece, a specialized scribing attachment can be used in place of the measuring jaw.
How to use height gauge?
Height gauges are used in quality control applications and can perform several types of measurements: 1 To measure the distance from a reference surface to a specific feature of a part to verify that it meets specifications and tolerances 2 To scribe a part with accurate vertical dimensions or features from a datum plane so that additional machining can be done 3 To perform 2D measurements of part features 4 To verify center-to-center dimensions 5 To measure flatness 6 To measure angles 7 To measure straightness/squareness or perpendicularity of parts
What is a digital height gauge?
Digital counter height gauges combine a dial and needle as found on the dial height gauge type with a dual-digit counter to increase the speed and efficiency of the measurement process . The counter will allow readings to tenths of an inch while thousandths of an inch can be read on the dial. The presence of an additional counter also has the advantage in that it enables users to set and maintain an absolute and floating zero if needed.
What is the measurement range of a dial height gauge?
Dial height gauges tend to be available in smaller measuring size ranges, typically less than 12 inches or 300 mm. These units feature a mechanical dial with a needle pointer that allows for easy reading. Because of their size, dial height gauges are very portable and can be stored in a toolbox.
What does variation in the reading on the height gauge indicate?
Any variation in the reading on the indicator reflects that the surface level is not correct, and the stoning and cleaning steps need to be repeated to correct the condition. The use of gage blocks is also recommended to validate all dimensional readings taken by a height gauge.
What is used to measure and scribe part features from a datum plane?
When using a height gauge, a granite surface plate is typically used to measure and scribe part features from a datum plane.
What is a vernier height gauge?
This is where the digital vernier height gauge comes in. Height gauges are specialized tools to measure the difference in elevation between two points.
What is height gauge?
Height gauges are specialized tools to measure the difference in elevation between two points. They are basically a variation of the regular vernier digital calipers and can perform similar functions like measuring internal and external diameters in addition to step measurements and center line distances. Height gauges normally have accuracies of ...
How to clean a height gauge?
The first step like using any instrument is to clean the work area and make sure the surface on which the gauge is to be set up is smooth and free from dirt. Next clean and dry the surface of the height gauge. Now attach the measuring jaw of the height gauge and clean it as well.
