In the early 1960s, my country's electronic scales were simple machines.
Electrical combination type, complex operation, poor human-computer interaction, accuracy and stability are relatively low and can only perform a single weighing function. Many companies also specialize in a foundation pit was dug for the large electronic scale and personnel and workshops were set up. Sixty over the years, after the rapid development of electronic weighing technology and computer technology, my country's electronic scale weighing technology has developed from the initial electromechanical combination model.
To the current fully electronic and digital intelligent models, measurement methods have also evolved from analog models.Simultaneous measurement has been upgraded to digital measurement, and the weighing method has changed from the original static weighing method.
With the development of combined dynamic and static weighing, the operation is becoming more and more simple and functional.The functions are becoming more and more abundant and intelligent, and their application scope covers energy, transportation, mining and metallurgy.
Gold, coal chemical industry, aerospace, wholesale and retail, manufacturing, environmental protection care and other aspects of daily life.
