What is an electronic truck scale? Truck scale (or called weighbridge) is the main weighing equipment used for bulk cargo measurement. Before the 1980s, ordinary truck scales were usually mechanical truck scales with a purely mechanical structure using the principle of leverage, also known as mechanical weighing scales. In the mid-1980s, with the maturity of high-precision load cell technology, mechanical platform scales were gradually replaced by electronic truck scales with high precision, good stability and easy operation. The electronic truck scale weigh goods via using the principle of strain electric measurement, and the strain gauge is connected to the elastic body of the load cell to form a Wheatstone bridge. When there is no load, the bridge is in equilibrium and the output is zero. When the elastic body bears a load, each strain gauge will produce a strain proportional to the load, and the external load can be measured by the output voltage. So how long is the service life of the electronic truck scale? Some people feel 8 years, some feel 10 years, and the most widely spread is 15 years. There are different opinions. How long is it? I believe that many people cannot give a definite answer on the use time of electronic truck scales. The following we will introduce to you the service life of electronic truck scales, let's have a look! Generally speaking, there is no mandatory obsolescence period for electronic truck scales.

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

Verification and Maintenance of Electronic Truck Scale Electronic truck scale (static) is one of the most widely used weighing instruments in our country. Electronic truck scale is a large scale, which is mainly used for weighing the weight of vehicles and used to weigh bulk goods in factories, mines, enterprises, etc.,. Generally speaking, an electronic truck scale is composed of a load-bearing device (scale body), a load conversion mechanism (weight sensor) and a load measuring device (weighing display instrument or weighing display). 1.Electronic truck scale verification (1)The verification of electronic truck scale is divided into first verification, follow-up verification and in-use verification. ①The first verification is the verification of the electronic truck scale that has not been verified. The first verification items are divided into zero setting and tare equipment accuracy test, weighing test, tare measurement test, partial load test, dis
