The weighed object or truck is placed on the platform of the carrier, and under the action of gravity, gravity is transmitted to the load cell through the carrier, so that the elastic body of the load cell is deformed. The strain gauge bridge attached to the elastic body loses balance, and outputs an electrical signal that is in direct proportion to the weight value. The signal is amplified by a linear amplifier, and then converted into a digital signal through AD, The weight data is directly displayed after the weight signal is processed by the microprocessor CPU of the instrument. After the printer is configured, the weighing data can be printed and recorded. If the computer and weighing management software are configured, the measuring data can be comprehensively managed through the weighing management system.
The truck scale can weigh the weight of the car, and it is very accurate, so it is widely used in various industries, but some of our Electronic weighing instrument manufacturer The writers of have little knowledge about the car wash, and the price of the weighbridge does not know what operations cannot be used on the truck scale in daily work, which causes various failures of the truck scale and wastes some unnecessary expenses and troubles of the enterprise. Now, we will teach you how to operate correctly and what to pay attention to. Pay attention to the following points when using truck scale.
According to the introduction of the electronic weighing instrument manufacturer, the weighing instrument manufacturer shall observe whether the instrument display is gross weight zero before each vehicle is mounted on the truck weighing platform: observe whether the instrument display is stable before printing or recording data. The loaded vehicle shall be mounted on the truck scale platform at a constant speed, and the speed shall be controlled within 5Km/h. Emergency braking is prohibited on the scale platform, and speed limit signs shall be made. When there is a vehicle on the scale, it is not allowed to cut off the power of the instrument. If the power is cut off temporarily, the vehicle shall be taken off the scale platform after the power is restored, and the meter shall be re measured after the zero point of the instrument is restored. The truck load measured each time shall not be greater than the weight, but not less than the weight of 20d.
It is forbidden to weld or use the scale platform as ground wire on the scale platform. During the installation of truck scale, the site shall be selected as far as possible to avoid being transported on the public passageway. Vehicles that are not measured in the production process of the weighbridge are prohibited from passing the weighbridge platform at high speed. The weighbridge in food processing or grain industry shall be well rat proof, and the joint shall be well waterproof when the cable is broken; Cables shall be sleeved with metal hoses. When the temperature is low in winter, the instrument will be powered on for 20 minutes before metering. The electronic weighing instrument manufacturer believes that the characteristics of the weighbridge should be waterproof in spring and summer, and dry agent should be placed in the junction box of the weighbridge without foundation pit; The sewage and drainage pipes in the shallow foundation pit weighbridge foundation pit shall be unblocked. Correct and standardized use of truck scale can make the service life of truck scale longer.
