Use these attachments to mount indicators in chucks, tool posts, height gauges, or a variety of other setups. If the zero line lands just past the 2.35-inch marking on the vertical shaft, and the best-aligned number on the vernier scale is "4," then the final measurement height is 2.354 inches. When the pin contacts a surface, pressure forces the pin lever up, causing the dial gauge to move. As with dial indicators, however, custom dial faces are available for test indicators … Record the last visible number located under the measuring equipment on the vertical shaft. Adapt metric dial indicators for use with standard inch-size contact points. Acceptable Limit: +/- 0.001" or 0.025 mm.

Depending on the level of accuracy and features, electronic height gages can be divided into three different groups: As you’ve probably gathered from the information above, the variety of height gauges is pretty broad. Gages in this group may also have additional features, such as tolerance setting, ID/OD measurement, max./min., TIR and probe compensation. Attaching Dial Test Indicator to Height Gage I'm not having much luck finding an adapter to attach a dial test indicator to my Mitutoyo height gage. To do so you’ll need a test indicator. long scriber or lever-type dial indicator is used, the measurement error becomes larger. When scribing, securely lock the slider in position using the clamping Mount a test indicator to the scriber and bring the indicator to the surface or reference part. Keep the column, which guides the slider, clean. The round nose of the scriber cuts clean, sharp lines with smoothness and less pressure and can reference zero from the bottom of the base to get the full usable range. The hand-operated feed wheel raises and lowers the gauge on the beam with smooth, even travel, and is selectable for coarse or fine feed. Measuring Offset Using Dial Indicators 3.

They are much more capable than calipers, but not as complex (and expensive) as a coordinate measuring machine (CMM). Relatively simple to operate, their main advantage over other height gages is the range of sizes they come in, meaning they can be used to accurately measure a wide range of workpieces. For example, if the shaft reads 1.2 inches, and the needle on the dial face is pointed to "53," the final height measurement is 1.253 inches. Contact Points for Interapid Most height gages come with a scriber by default. In simple terms, a height gage is a bench top tool commonly used to either measure vertical distances or make repeated markings on a part. Please read our disclosure for more info.
