Digital Platform Scale (orweigh scales或者秤) are devices to measureweight。Spring balances或者弹簧鳞片calculateweightthat is the product of mass into gravity (9.807 m/s2) on the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of one or more known masses. Some of them can be calibrated to read in units of force (weight) such as纽特而不是质量单位kilograms。使用传统平衡梁的平衡或一对刻度可以正确地读取质量，即使移动到具有不同的非零引力场强度的位置也可以正确读取质量。此外，设计精心设计的弹簧平衡，可以在不同的非零引力场强度下正确读取重量的重量。
秤和余额广泛用于商业，因为许多产品被销售和包装受到质量。
虽然约会到1700s的记录是指用于测量质量的弹簧尺度，但是最早的设计为这一设备的设计日期为1770年，并获得早期规模制造商的学分理查德盐门。[1]在1840年后，当R. W. Winfield开发了用于称重字母和包裹的烛台规模后，春季尺度在英国进行了广泛的用途。Uniform Penny Post。[2]Postal workers could work more quickly with spring scales than balance scales because they could be read instantaneously and did not have to be carefully balanced with each measurement.
By the 1940s various electronic devices were being attached to these designs to make readings more accurate.[1][3]Load cells, small nodes that convert pressure (or force) to a digital signal, have their beginnings as early as the late nineteenth century, but it was not until the late twentieth century that they became accurate enough for widespread usage.[4]
机械秤[edit]
A mechanical scale or balance is used to describe a weighing device that is used to measure the mass, force exertion, tension and resistance of an object without the need of a power supply. Types of mechanical scale include spring scales, hanging scales,triple beam balancesand force gauges.
