DIGITAL DEPTH GAUGE MICROMETER INSTALL

It is possible to buy depth bases with 2-1/2' or 4' spanning widths and attach these to any dial indicator you already own. The use of dial indicators allows you to choose from a variety of resolutions and accuracies up to. Since the spindle pressure is constant and slight, the readings are not likely to be distorted because of over-tightening in the case of micrometers, or unconscious fudging in the case of calipers. The depth base spans the opening, keeping the indicator steady and giving you perpendicular entry into the hole, slot or groove.Ī lifting lever at the top of the indicator allows you to easily lift and release the gaging plunger (the indicator spindle). This is, in effect, a dial indicator with a depth base attached. positioning can be unsteady without the added depth base.

long range up to 6 inches without having to change or install extensions.

Depth bases designed for use with calipers are shown on page 173.Īdvantages of using the dial caliper for depth measurement: This is absolutely necessary for an accurate reading.īecause the thickness of the caliper beam varies from manufacturer to manufacturer, depth bases may not always be interchangeable between makes. The base allows you to firmly position your calipers over the opening in order to get a perpendicular entry into the hole. In other cases you may need to buy it separately. Before tightening the screw, place the caliper on a flat surface to make sure the depth base is flush with the end of the caliper. These simply slide on and are clamped in place with a screw. 060' diameter for measuring depth.įor best stability when measuring, attach a depth base to the end of the calipers. If you need to measure the depth of small holes you may be interested in the Shop-Cal which has a thin cylindrical rod of. This dimension may limit its use, but the rod could be filed or ground to a specific profile, as long as it does not affect the length of the rod. 145' on Brown & Sharpe, Tesa and Etalon 6' calipers. Obviously you can measure depths equal to the extended length of your calipers. 001', at least for the first 4 inches of travel. The depth rod which protrudes from the end of the calipers, as you open them up, is used to measure depths with a resolution of. The simplest depth gage is one you probably already have in your possession: the dial caliper. Using calipers, depth gages and depth micrometersĪs always, the equipment used depends on the application.
