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. Hand calipers are measuring instruments that can measure a variety of items such as length (outer shape), inner diameter, and level … The springing of the measuring jaw should be always avoided. Things I didn’t … Height gauges may have an offset scriber and the scale on the beam so positioned that when the scriber is coplanar with the base, the vernier is at zero position. 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. A common and simple mechanical vernier height gauge has a least count of 2 0.02 mm. 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. Following are the uses of vernier height gauge: Vernier height gauges … 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. Double Column Electronic Digital Vernier Height Gauge , Find Complete Details about Double Column Electronic Digital Vernier Height Gauge,Height Gauges,Digital Height Gauge,Vernier Height Gauge from Gauges … Notify me of follow-up comments by email. The projection of a scriber beyond the jaw should be at least 25mm. A Vernier height gauge is a measuring device used either for determining the height … Running through the depth gauge … Height gauge definition is - a gauge having a micrometer or a vernier scale for measuring heights. The use of the vernier scale is shown on a vernier caliper which measures the internal and the external diameters of an object. How to Read the Scale Graduation : 0.05mm(VHK-15,20) Graduation : 0.02mm(VHK-30,60) 2 As with vernier calipers, the scale is read off the main scale and off the vernier … CERA Caliper Checker Series 515. 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 … Following are the main parts of vernier height gauge: The base is made to high proportions to ensure rigidity and stability of the gauge. Custom gauges may extend the column height even higher. The graduated scale has least count of 0.02 mm like Vernier Caliper has. Operators may use this functionality to mark many pieces of metal with identical and precise measurements. In addition to sliding jaw assembly, provision is provided to carry a removable clamp. If you have any questions about any topic you can ask in the comment section. So for a vernier with a constant of 0.1, each mark on the vernier … Is Amazon actually giving you the best price? As seen in the image above, height gages are composed of several different parts. Standard gauges are used for testing purpose. We have also Facebook community for you guys, if you want, you can join our community, here is the link to our Facebook group. Vernier Height Gage Series 514-Standard Height Gage with Adjustable … Thatâs it thanks for reading. About $262.99 on Amazon. Wikibuy Review: A Free Tool That Saves You Time and Money, 15 Creative Ways to Save Money That Actually Work. 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. If you like our article then please share it with your friends. The various parts and nomenclature of height gauge are shown in the figure given below: Least count is the difference between one smallest reading of the main scale and one smallest reading of vernier scale. A height gauge can also be used to set the height of a desired measurement or the height of a part. Digital height gauges may be more expensive than their vernier counterparts, but typically take less training or expertise to read correctly. The name of this tool is derived from the special, sliding vernier scale that the devices make use of. Vernier height gauges are used to determine or measure vertical distances in metrology or metalworking. Following are the uses of vernier height gauge: So now, we hope that we have clear all your doubts about Vernier Height Gauge. Clear specification of the range of measurement. The guiding edge should be perfectly flat within the tolerances of 0.02, 0.04, 0.06, 0.08mm for measuring a range of 250, 500, 750, 1000mm respectively. At a distance of 25 mm from the end of the jaw, the test measurements are made. Swiss Precision. 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. To ensure rigidity during use, the cross-section is chosen. Any specific requirements regarding the type of vernier desired. 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. As the name suggests, it is a device for measuring the height of an object. 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. Vernier scales are an additional measurement tool that can augment a straight scale and allow for more accurate measurement. The errors in any portion within the measuring range of height gauge should not exceed Â±0.02mm for 250mm height gauge, I0.04 mm for above 250mm and up to 750mm, I0.05mm for large more than 750mm. A height gauge is a measuring device used for determining the height of objects, and … In the many of industrial jobs where some measurement is required we may face different nature of values for measuring like depth, breath, height and length … What is vernier height gauge? Typically a scriber, test indicator, touch probe, or CMM-style probe is used to detect the measured feature. Here the graduated scale is slide through the base and vernier scale remains fixed. 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 Vernier height gauge has a vernier caliper, equipped with a special base block, measuring jaw, and other attachments which make the instrument suitable for height measurements. This system can allow for a much higher measurement resolution than is normally possible with a straight scale. It can be used to measure only small objects. Even a magnifying lens is provided to facilitate to take readings. 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. The following sketch shows the common errors of the vernier height gauge. He is also an author and editor at theengineerspost.com. 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.
