This will show how to properly measure parts and how to read to the thousandths. The way of taking measurement of vernier depth gauge is same as vernier caliper has. It indicates a range of 0 to 1 inch and, more importantly, it … Picture a dial test indicator head-on, looking at the dial, or dial face. Quick and easy measurements of small parts and thicknesses are made with these hand-held tools. Digital type dial gauge is more accurate than Dial display. How depth is considered safe and how depth is considered as requiring very soon replacement. Place the bore gauge in a micrometer locked to the same diameter of the hole being measured. Since most calipers have more than OD jaws, make sure to check the tool’s ID jaws and depth-measuring rod, should it have one. See figure 2-30; consider the reading shown. Accuracy. You shouldn’t do the determination of depth using the jaws on the caliper unlike inside and outside measurements. wikiHow's. Step 3 involves actually reading the dial test indicator. The knife-edge base has a cutout so that the conical point can be precisely positioned for close work. Point is 1/2" (12.7mm) long with a 40 Deg included angle. Attach the pinion depth tool to the rear end of the differential housing (with the supplied mechanical clamps). A Vernier gauge is a useful measurement device equipped with two scales, one fixed and one that slides. The inner face, which is small and stationary, keeps track of the number of revolutions. A typical set of gears comes with a marking compound. To read a dial indicator, start by mounting it on a stand to stabilize it and calibrating the dial by turning the outer face until the hand points to 0. directly from the rack and the dial indicator. Looking for INSIZE Dial Depth Gauge, Depth Gauge Type Interchangeable Rod, Range 0 in to 12 in, Base Style Full (463J22)? Measurement scale – depth gauge measurements are typically shown in inch or metric (millimeter) values, with some … The 2.5″ x 3.75″ gauge is designed with an elongated knife edge stabilizer and a cut-out for positioning the pinpoint stylus directly over the pit for optimum measurements. Next is 0.279”. Measuring Procedure • For measuring lengths greater than 25mm add the necessary amount of measuring rods for the depth required. Dial indicator comes with different contact point vary according to the application. Count the tick marks the little hand has passed. On the dial face you References. Setting a dial bore gauge is a simple concept. dial thickness micrometer - medor de espesores. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Some normal characteristics of Depth Micrometer describe follows. Quick reference color coded scale and 1/32″-1″ sliding range. More about Tresna Instrument. Most of these tools The following information covers digital calipers but can also be used for dial or even Vernier calipers, if those are still in use. ﬁgures). 0 to 22 Inch Range, Steel, White Dial Depth Gage 0.001 Inch Graduation, 0.001 Inch Accuracy, 1 Inch Travel, 4 Inch Base Measuring Length. Depth micrometers have a base that aligns with the top of the recess that needs to be measured. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. Then read the measurement that you can see on the digital indicator. Most dial faces are graduated in .001-inch hash marks so that one full revolution of the indicator needle equals one tenth of an inch or .100-inch travel. The dial indicator uses a calibrated stem that transfers linear movement to an easy to read dial face. Grainger's got your back. Step 3 How to Read A Tire Tread Depth Gauge. ... – Value read in the instrument . Sometimes there are exceptions. or runout present. Also the direction of the graduations is reversed from that of a "normal" indicator. wikiHow is where trusted research and expert knowledge come together. Then there is a sliding panel that goes around the ruler, which has a wide platform that angles downwards into a flat section. In order to keep a check on that a tread depth gauge is what you need. The bezel surrounds the dial face, and Vernier scale is moveable on main scale. That said, here are some analog gages that might still serve a useful purpose. Then, spin the bezel such that the zero point is once again aligned with the pointer. How to measure depth with Vernier Depth gauge? For example, if one revolution equals .1-inches, then you would calculate three marks on the small gauge as 3 X .1=.3-inches. Any difference in the depth results in glue lines. Like other simple tools, you could intuitively use it. If yours does, consult the instruction documents for more information about the extra faces. Probe indicators typically consist of a graduated dial and needle driven by a clockwork (thus the clock terminology) to record the minor increments, with a smaller embedded clock face and needle to record the number of needle rotations on the main dial. This linear measuring tool is very easy to use. The Starrett 643 Series Dial Depth Gauges, Indicator Type, Inch, have a measurement range of 0 to 0.125", a resolution (or smallest graduation interval) of 0.0005", with + or - 1 graduation (0.0005") for the first 2.5 revolutions of accuracy.
