What is the working principle of electronic crane scale?

The working principle of electronic hanging scale: when the load is acted on the sensor by the hook, the elastic body of the sensor changes slightly, so that the resistance value of the resistance strain gauge attached to the elastic body changes, and the balance of the bridge is changed. The output voltage changes, the voltage signal changes through high speed and high precision A/D converter into A digital signal, the digital signal through the collector, wireless transmitter (or cable) transmission to the secondary instrument. The secondary instrument will get the signal for data calibration processing, the corresponding weight value to the display screen display, but also can be printed by a printer, when necessary, can be transmitted to the computer management system. Matters needing attention when using hanging scale 1. Avoid using or storing in places with high temperature, humidity, high dust concentration or serious vibration. 2. Do not strongly impact, pay attention to the weighing 3. It must be used within the specified voltage range, otherwise it will cause damage. 4. Do not weigh overloaded goods, so as not to damage the sensor. 5. Unplug the power plug when not in use for a long time. 6. Read the manual carefully before use and fully understand the function of the scale. 7. The scale body should be kept clean, do not wash with water
