This system can allow for a much higher measurement resolution than is normally possible with a straight scale. This is typically achieved by a fixed scale printed along the length of the measuring device, while a sliding vernier scale is on the moving component. It is possible to measure many different things with the gauge, but they are most often used in metalworking and other related industries. Vernier height gauges are one of the two main types of tools used to make accurate vertical measurements. The left height gauge has the vernier scale, while the right one is an electronic height gauge with a digital readout. In addition to sliding jaw assembly, provision is provided to carry a removable clamp. A digital height gauge and granite surface plate should come fairly early in your Metrology investment schedule given how useful they can be. 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. In this post, youâll learn what is vernier height gauge itâs Least count, diagrams, nomenclature, and parts, errors and uses of the vernier height gauge. In specifying the vernier height gauge three main factors are important and they are: In general, all the parts of height gauges are made of good quality steel or stainless steel. The name of this tool is derived from the special, sliding vernier scale that the devices make use of. Standard gauges are used for testing purpose. In long height gauges, to avoid its heating by warmth from the hands, care should be taken.

The carriage mov… During fabrication. A vernier height gauge is typically used to take precise vertical measurements of various objects. Rather than a vernier scale, these gauges have a digital readout. The other scale on the other side has inches, but nobody uses those any more. Anyone doing construction or remodeling work and in need of accurate measurements of the depth of a slot, hole or recess will find a Vernier depth gauge … Using the Thread Pitch Gauge and Comparator to count the amount of threads per inch, then the vernier calliper to measure the length of the head which came out to be 1.101in., its depth to be 0.457in., full … In 1968 the Trimos Company produced a digital height gauge … The parallelism of the measuring jaw and scriber with the base. What is a height gauge? Specifications. 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. For many years the Swiss have been synonymous with precision measurement equipment and measuring devices, and it was a Swiss company that made the first major advance on the Vernier Height Gauge.. 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 beam or column height can vary from 6 inches or less to upwards of 6 feet, depending on the model. Is Amazon actually giving you the best price? The springing of the measuring jaw should be always avoided. If you have any questions about any topic you can ask in the comment section. Imperial height gauges measure heights up to a maximum of 48" using a main scale and vernier scale graduated to read to 0.001". CERA Caliper Checker Series 515. This site uses Akismet to reduce spam. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. Thatâs it thanks for reading. Following are the main parts of vernier height gauge: The base is made to high proportions to ensure rigidity and stability of the gauge. 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. Notify me of follow-up comments by email. This may be necessary if the scribing tool becomes worn or damaged, and is often adjusted through the use of a feed screw. Saif M. is a Mechanical Engineer by profession. A Vernier height gauge is a measuring device used either for determining the height … The other type is typically referred to as an electronic height gauge. 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. As the name suggests, it is a device for measuring the height of an object. 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. These faces should be square to base within 0.04mm / 100mm. The graduated scale has least count of 0.02 mm like Vernier Caliper has. Two main types of height gauges … The underside of the base is relieved leaving a surface round the outside edge of at least 7mm width and an air gap is provided across the surface to connect the received part with the outside. The scriber, used to mark a position on a workpiece, is 32 mm x 80 mm (H x W), carbide-tipped for hardness and to help prolong life, and is held to the gauge … On Vernier height gages, the beam typically features two engraved scales (imperial and metric) that take the main measurement. A height gauge is a measuring device used for determining the height of objects, and … Even a magnifying lens is provided to facilitate to take readings. When the zero mark on the sliding scale is located between two graduations on the fixed scale, the operator can find the location where the vernier and fixed graduations line up to determine a precise measurement. Uses of Vernier Height Gauge. It can be used to measure only small objects. Vernier Calipers/Height Gauges (Depth Gauges) Overview. It is mainly used in the inspection of parts and layout work, with a scribing attachment in place of measuring jaw, this can be used to scribe lines as the certain distance above the surface. A common and simple mechanical vernier height gauge has a least count of 2 0.02 mm. Height gauge definition is - a gauge having a micrometer or a vernier scale for measuring heights. 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. About $262.99 on Amazon. Running through the depth gauge … This little known plugin reveals the answer. Right? In order to ensure the continued accuracy of a gauge, it is typically possible to adjust the level. 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. Digital height gauges may be more expensive than their vernier counterparts, but typically take less training or expertise to read correctly. He completed his engineering studies in 2014 and is currently working in a large firm as Mechanical Engineer. The following sketch shows the common errors of the vernier height gauge.
