Weighing instrument, also known as weighing display and control instrument, is the load cell signals (or then through the weight transmitter) converted to digital display of weight, and can be stored on the weight of data, statistics, printing of electronic equipment, commonly used in industrial and agricultural production of automated dosage, weighing, in order to improve production efficiency.

5, electronic platform scale

Electronic platform scale is the use of electronic strain elements deformation principle of force output small analog electrical signals, through the signal cable to the weighing instrument, weighing operation and display the weighing results of the weighing apparatus.
