  2. Triple beam balance - Wikipedia

    en.wikipedia.org/wiki/Triple_beam_balance

    Base - The base rests underneath the weighing pan and can usually be customized to fit on a workbench or set up with tripod legs. Beams - The three beams on the balance are used to set the level of precision, with each beam working at different increments (1-10 grams, 10 grams and 100 grams). When using the triple beam balance, it is ...

    Online sensors are set on the scanner beam to scan across the web. Typical crossing time of the web in new systems is 10–30 s (8m web, 60 cm/s). If the web speed is 1200 m/min and web width 8.5 m, the web moves 280 m during a scan, and the sensor moves the same distance diagonally across the web.

    A checkweigher is an automatic or manual machine for checking the weight of packaged commodities. It is normally found at the offgoing end of a production process and is used to ensure that the weight of a pack of the commodity is within specified limits.

    Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st

    Typical accuracy figures are: Planarity of a 2-foot (0.61 m) wide surface, to 10 micrometres (0.00039 in). Shape of a motor combustion chamber to 2 micrometres (7.9 × 10 −5 in) (elevation), yielding a volume accuracy 10 times better than with volumetric dosing. Shape of an object 2 inches (51 mm) large, to about 1 micrometre (3.9 × 10 −5 in)
