Gauge wheels mounted near the end of the boom will maintain uniform boom heights. Using a “Cadillac” gauge will also expand the capabilities of these height gauges and test indicators…. The gage must be zeroed before measuring parts. Terms and Conditions, Truck-mounted units use spinners or booms for distribution. Not only is the dial easier to read than a Vernier scale, but the dual-digit counters allow one counter to be set at the reference datum and the other to be used as a floating zero. Sometimes engineers design unique mounts to support the instruments for special jobs. Height gages are used to set and mark a certain height on the workpiece, or to measure the piece after it has been machined. The carriage movement is controllable and may be adjusted by a set of adjustment screws for coarse or fine adjustments and may be locked into position as needed. The steel bar is 3 cm wide and 1 cm high and it is subjected to a tensile Force of F-30 kN. Accuracy is sometimes defined as a +/- percentage of the full-scale value of the gauge or as an absolute value in length units. Mount a test indicator to the scriber and bring the indicator to the surface or reference part. The desired result was 2.396″. 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. Dial height gages are usually for smaller measurements of less than 12 inches, but are therefore great as a transportable tool that is easy to store. Thomas Regional® are part of Thomasnet.com. The dial makes reading the device easier than a Vernier scale. The carriage … The typical indicator holder is a magnetic-based stand that has an arm, or arms, to hold the measuring apparatus in a variety of positions. Repeatability – also called precision, is  a measure of the gauge’s ability to generate the same reading for a measured dimension on a given part when that measurement is performed many times. [So, if mounted on a 2-inch diameter pole, the boom should extend out 6 inches away from the pole]. • Ideally located at a horizontal distance of 4 times the height of the nearest obstruction.
