Mechanical Scale. Any of several mechanical devices that measure the weight of an object. The two most common types are spring scales and balances. A balance measures the weight of an object by comparing it to standardized weights. In compares the weight of the object placed in a pan on one end of the balance with standard weights placed in a pan on the other end. A spring weighing scale measures the forces necessary to stretch or compress a spring and convert this displacement to weight on an analog indicator.

Weight Transmitter. An electronic device that processes the low voltage electrical output from mechanically deforming load cells, amplifies that signal, and uses it to operate an integrated digital or analog readout, or to control another device. A load cell is a transducer which converts force into a measurable electrical output. Although there are many varieties of load cells, strain gauge based load cells are the most commonly used type. They offer accuracies from .03% to .25%full scale, and are suitable for most industrial applications.
