The parts of triple beam balance are identified as the following. [3]Weighing pan - The area in which an object is placed in order to be weighed.; Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs.
In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits. It is a useful item in a small parts machine shop or production line for the quality control inspection team. The measuring happens in any of several ways.
An analytical balance (or chemical balance) is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg resolution or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation ...
Inside small jaws: used to measure the internal diameter of an object (like a hollow cylinder or pipe). Depth probe, or depth rod: used to measure depths of an object (like a small beaker) or a hole. Main scale (metric): marked every millimeter and helps to measure length correct up to 1 mm. Main scale (imperial): marked in inches and fractions.
Four measuring devices having metric calibrations Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. [ 1 ] [ 2 ] In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same ...
The part being checked must pass through the first gap and must stop at the second gap in order to be within specification. The two gaps accurately reflect the top and bottom of the tolerance range. Bore micrometer, typically a three-anvil head on a micrometer base used to accurately measure inside diameters.
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
A protractor is a measuring instrument, typically made of transparent plastic, for measuring angles. Some protractors are simple half-discs or full circles. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle. Most protractors measure angles in degrees (°).
