A height gauge is a measuring device used for determining the height of objects, and for marking of items to be worked on. [ 1 ] These measuring tools are used in metalworking or metrology to either set or measure vertical distances; [ citation needed ] the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
Vernier height gauge: a measuring device used either for determining the height of something, or for repetitious marking of items to be worked on. The former type of height gauge is often used in doctor's surgeries to find the height of people. Wire gauge: measuring tool determines the thickness of a wire.
Topographer's rods are special purpose rods used in topographical surveys. The rod has the zero mark at mid-height and the graduations increase in both directions away from the mid-height. In use, the rod is adjusted so that the zero point is level with the instrument (or the surveyor's eye if he is using a hand level for low-resolution work).
Depth gauge or height gauge. Form of marking gauge for marking lines parallel to an edge, by setting the head to a certain distance from the end of the rule. [6] Reference for directly transferring dimensions without needing to take a measurement, minimising measurement errors and inaccuracies. [7]
The cockpit of a Slingsby T-67 Firefly two-seat light airplane.The flight instruments are visible on the left of the instrument panel. Flight instruments are the instruments in the cockpit of an aircraft that provide the pilot with data about the flight situation of that aircraft, such as altitude, airspeed, vertical speed, heading and much more other crucial information in flight.
Gauge blocks (left in each picture, under optical flat) being used to measure the height of a ball bearing and a plug gage using interferometry. The interference fringes (lines) visible on the surface of the flats indicates error; the number of lines indicates the amount.
Snap go/no-go gauge for the OD of a cylindrical workpiece Thread snap gauge. Snap gauges are often used when a large quantity of work pieces must be inspected. [4] The snap gauge has four anvils or jaws, the first one or pair (outermost) are set using the upper limit (tolerance) of the part and the inner set adjusted to the lower limit of the ...
Angles are measured using a sine bar with the help of gauge blocks and a dial gauge or a spirit level. The aim of a measurement is to measure the surface on which the dial gauge or spirit level is placed horizontally. For example, to measure the angle of a wedge, the wedge is placed on a horizontal table. The sine bar is placed over the ...
