Vernier height gauges are one of the two main types of tools used to make accurate vertical measurements. It is also used to measure straightness, squareness, or perpendicularity of objects. Whenever the vernier height gauge is not used, it should be kept in their cases. The following sketch shows the common errors of the vernier height gauge. What is a height gauge? Its Advantages and Disadvantages, Mechanical Pressure Gauges: Types, Working, Applications, Advantages. You have entered an incorrect email address! The rigidity should be such that an upward force of 1kg applied at the tip of the scriber when the measuring jaw is in its highest position such that there is no change in the parallelism of the jaw with the base of more than 0.005mm / 10mm of projection of the working surface of the scriber. If you have still any doubts about “Vernier Height Gauge” you can contact us or ask in the comments. A Vernier height gauge is a measuring device used either for determining the height … The following are the most important precautions to be taken without fail: For testing the accuracy of the vernier height gauge, the following conditions must be adopted: The major tests on vernier height gauge are straightness, squareness, the parallelism of the working faces of the beam, measuring jaw and scriber and the accuracy of the scale readings are done by following methods. It is lapped to an accuracy of 0.005mm as measured over the total span of the surface considered. These measuring tools are used in … Rather than a vernier scale, these gauges have a digital readout. There are analogue, or vernier (l), and digital (r) height gauges. That’s it thanks for reading. So for a vernier with a constant of 0.1, each mark on the vernier … Custom gauges may extend the column height even higher. CERA Caliper Checker Series 515. The projection of the measuring jaw from the edge of the beam should be at least equal to the projection of the base from the beam. Vernier height gages are used to mark out lines when accuracy is particular importan and widely used on surface plates and on machine tables. Heights or vertical distances may also be measured using the bottom of the scribe. Specifications. The faces should also be flat within the tolerances of 0.04, 0.06, 0.10, 0.12mm for vernier heights of 250, 500, 700, 1000mm respectively. The vernier scale is constructed so that it is spaced at a constant fraction of the fixed main scale. The left height gauge has the vernier scale, while the right one is an electronic height gauge with a digital readout. Learn how your comment data is processed. Clear specification of the range of measurement. The bottom side of the scribing tool can also be used to measure vertical distances, rather than inscribing height markings. A proper fitting is included to give a precise adjustment of the slider and suitable clamp fitted so that the slider can be effectively clamped to the beam after the final adjustment has been made. The standard reference temperature of 20°C shall be maintained in the room, wherever the test is being conducted. In 1968 the Trimos Company produced a digital height gauge … For all the above measurements, the use of surface plate is very much essential. For any position of the slider, the upper and lower gauging surfaces of the measuring jaw should be flat and parallel to the base within 0.008 mm. A Vernier gauge is a useful measurement device equipped with two scales, one fixed and one that slides. The parallelism of the measuring jaw and scriber with the base. Vernier height gauges are one of the two main types of tools used to make accurate vertical measurements. You may be interested in reading this articles: Save my name, email, and website in this browser for the next time I comment. The Mitutoyo 514-102 vernier height gauge has a measurement range of 0 - 300 mm, and is graduated to 0.02 mm, with + or - 0.04 mm of accuracy. Height gauge definition is - a gauge having a micrometer or a vernier scale for measuring heights. By resting the height gauge on precision surface plate various tests are being carried out. Notify me of follow-up comments by email. The underside of the base, faces of the measuring jaw and scriber are hardened to about 700 HV or 58 RHC for good quality steel and up to 650 HV or 56 RHC for stainless steel. The upper and lower surfaces of the measuring jaws are parallel to the base so that it can be used for measurements over or under a surface. Uses of Vernier Height Gauge. Subscribe our YouTube Channel for More! The other type is typically referred to as an electronic height gauge. A vernier height gauge is typically used to take precise vertical measurements of various objects. Rather than a vernier scale, these gauges … Vernier Height Gage - Series 506-Light Weight Height Gage.

A height gauge can also be used to set the height of a desired measurement or the height of a part. In this post, you’ll learn what is vernier height gauge it’s Least count, diagrams, nomenclature, and parts, errors and uses of the vernier height gauge. He completed his engineering studies in 2014 and is currently working in a large firm as Mechanical Engineer. Vernier scales are an additional measurement tool that can augment a straight scale and allow for more accurate measurement. If you have any questions about any topic you can ask in the comment section. On this channel you can get education and knowledge for general issues and topics A digital height gauge and granite surface plate should come fairly early in your Metrology investment schedule given how useful they can be. In case of digital type vernier depth gauge result can see in liquid crystal display with a maximum measuring speed of 1.5 m/s. It can measure extremely precise distances, in some cases to .02 mm. Vernier height gauge is a special type of vernier instruments which is used to measure heights of different engineering objects up to high precision and accuracy during many of industrial jobs where measuring process is require. This will often take the form of adjustable level so that it can be set to particular heights and then used to scribe marks on a piece of metal. They often have a scribing tool as the measurement level, allowing the operator to repeatedly mark vertical distances on pieces of metal that can then be worked on. We have also Facebook community for you guys, if you want, you can join our community, here is the link to our Facebook group. The perpendicular distance between the graduations on scale and graduations on vernier should have a dull finish and the graduation lines blackened in. Vernier height gauges are used to determine or measure vertical distances in metrology or metalworking. 2.Turn the fine adjust feed screw to attain the desired height setting. When used in metalworking and other related industries, a vernier height gauge is typically equipped with a scribing tool.
