As a new generation of Truck Scale, Electronic Truck Scale is almost the same as Digital Truck Scale. It uses a separate Digital Junction Box to perform A/D conversion on the signal output by the analog sensor, so that the signal from the Junction Box to the instrument becomes a digital signal. It is used for weighing large goods, such as four-axle trucks, heavy goods, etc. .
Today, we will introduce the composition and measurement methods of electronic truck scales.
Firstly, let us talk about the structure and working principle of the electronic truck scale:
1. The structure of electronic truck scale.
Electronic truck scales are mainly composed of carriers, vehicles, load sensors, connectors, limiters, connection boxes, etc., and can be connected to peripherals such as large-screen displays, computers, and stabilized power supplies.
2. The working principle of electronic truck scale.
The objects on the loader are placed on the ground of the loader. Under the action of gravity, the gravity is transmitted to the weight sensor through the loader. The elastic body of the weight sensor is deformed, and the strain gauge bridge on the elastic body loses balance, and then the output electric signal proportional to the weight value is amplified by the linear amplifier, and then converted into a digital signal by A/D. The weight signal is processed by the microprocessor of the computer to display the weight data, configure the printer and print the recorded weight data. Through the computer, the measurement data can be input into the computer management system for comprehensive management.
Next, let us talk about the main technical indicators of the electronic truck scale.
1. Measuring object: standard four-axle truck, weighing less than 100T or 150T.
2. Working mode: dynamic connection, bogie metering or vehicle metering.
3. The driving speed of the weighing vehicle is 1-15 km/h, and it can reach 1-20 km/h if the straight line between the left and right sides of the weighing platform exceeds 50 meters.
4. The sensitivity of the measuring counter: When measuring the weight statically, add or subtract 20kg, and the change exceeds 10kg.
5. The zero drift should be less than 10 kg and last for 4 hours.
6. Measurement accuracy: please refer to the relevant regulations of JJG234-90 of the National Metrological Verification Regulations of the People's Republic of China.
7. Output mode: color display, digital output, display speed, weight data is easy to download, used to make tables, weighing results can be stored in the computer for a long time, and then statistical information can be inquired at any time.
8. Power supply: The power consumption of this device does not exceed 500 watts.
The above is the structure, working principle and main technical indicators of the electronic truck scale shared by Lude company. Through the sharing of us, do you have a better understanding of the electronic truck scale? See you next time!
