The weighed object or truck is placed on the table of the carrier. Under the action of gravity, the gravity is transmitted to the weighing sensor through the carrier, so that the elastic body of the weighing sensor is deformed, the strain gauge bridge attached to the elastic body loses balance, and the electrical signal proportional to the weight value is output. The signal is amplified by a linear amplifier and then converted into a digital signal by A/D, the weight signal is processed by the microprocessor (CPU) of the instrument and the weight data is displayed directly.

Working principle of electronic truck scale

instructions for use of electronic truck scale:

Electronic truck scale is a new type of electronic weighing instrument, with the characteristics of rapid weighing, high accuracy, intuitive display, complete functions, etc., suitable for industrial, commercial, construction, warehousing, freight stations, bazaars and other industries, is an ideal measuring instrument.

Chapter 2 System Composition and Working Principle

SCS series electronic platform scales are mainly composed of scales, weighing sensors and connectors, junction boxes, weighing displays and other parts.

Its working principle is: the mass of the goods to be measured acts vertically on the weighing platform, and the weighing platform transmits the mass Q to the sensor, causing the elastic body of the sensor to deform, and then causing the resistance value of the strain gauge attached to the elastic body and forming the Wheatstone bridge to change. The balance of the bridge is destroyed, and a voltage signal with a linear relationship with the size of Q is output. As the sensitivity of each sensor is different, therefore, under the action of the same quality Q, the voltage output of each sensor is slightly different, which affects the consistency of the scale. Therefore, a junction box should be connected to the system to make the output signal of each sensor consistent. The validity voltage signal output from the junction box is connected to the weighing display, and the measurement result is displayed digitally after being processed by the weighing display.
