Structure and maintenance of electronic truck scale

Time:2022.03.03     News sources: Hebei Chaoda Sealing Products Co., Ltd

Electronic truck scale structure

1. The bearing

(1) weighing platform

Weighing platform is generally made of metal materials, with a section, two sections, three sections and four sections of the points. It has high strength and hardness, and has sufficient area of use.

(2) scale bridge and connector

Scale bridge as the frame of the table has an irreplaceable role, its quality will affect the quality of electronic truck scale.

(3) limit device

The horizontal limit device of electronic truck scale can eliminate other interference and ensure the weighing result is stable and reliable. And the electronic truck scale overload limit device, is to protect the electronic truck scale device, and then protect and prolong its service life, to prevent serious overload of electronic truck scale damage.

2. Weighing sensor

At present, electronic truck scale adopts weighing sensor, especially resistance strain type weighing sensor. It is widely used as a sensor with high accuracy, good stability, mature technology and easy production.

The weighing sensor of electronic truck scale adopts a certain number of cantilever beam type or double cantilever bridge type weighing sensor according to the scale size and the length of table.

In order to overcome the differences in output impedance and sensitivity of multiple weighing sensors, the weighing sensors are connected in full parallel connection, and the adjustable precision resistance is installed in parallel connection at the output end of each weighing sensor accordingly, so as to ensure the accurate and reliable weighing results.

3. Measurement display system

The measurement and display system of the electronic truck scale amplifies the output signal of the weighing sensor in front, and then through A/D converter, microprocessor and display, the mass value of the goods on the electronic truck scale is finally displayed in the form of numbers.

Of course, electronic truck scale has other devices and printing devices and other components.

Electronic truck scale maintenance

L, in order to ensure the accuracy of the system measurement, from wind and rain erosion, conducive to operation, required to set up a workshop and measuring scale room.

2. There should be a 10-15mm gap at the junction of the scale platform and the lead slope, and collision and friction shall not occur.

3. The weight of the truck measured shall not exceed the rated weight value of the system.

4. In order to ensure the normal measurement of the weighing instrument, it should be verified regularly.

5. Foreign bodies shall not be stuck under the platform of the scale.

6, the scale operator must be trained to operate, repair personnel in the absence of the necessary knowledge, shall not be free to remove any parts, so as not to affect the measurement accuracy or damage the system.

7, the operator of the instrument, must be detailed digestion and absorption of the instrument manual, master the basic principle, familiar with the instrument maintenance method before formal operation and use.

8. Check whether the power supply and grounding device are reliable before the system is powered on. Unplug the power plug of the instrument and cut off the power supply after work.
