Description

Dynamic truck scale

Technical Field

The invention relates to the technical field of automobile scales, in particular to a dynamic automobile scale.

Background

Truck scales, also known as loaders and called truck scales, are large scales placed on the ground to weigh the tons of a truck, and are the main weighing devices used by factories, mines and other companies for weighing bulk goods. The truck scale can be divided into I-shaped steel loadometer, T-shaped beam loadometer, L-shaped beam steel loadometer, U-shaped steel loadometer, channel steel loadometer and reinforced concrete loadometer according to the structure of the weighing body, and can be divided into digital loadometer and analog loadometer according to the type of the sensor.

The dynamic truck scale is generally composed of a weighing area, a weighing sensor, a weighing display controller and the like. The weighing area consists of a load carrier and a transition belt, wherein the load carrier is a load bearing part; the weighing sensor converts the mass signal of the load into an electrical signal which is easy to measure; the weighing display controller amplifies, filters and A/D converts the signals, the signals are calculated by the CPU and displayed by the display, and a weighing result is printed by the printer.

The main components of the truck scale are weighing sensor, weighing platform, instrument, junction box, data line and slope guide (no-base type), the weighing sensor is the core component of the truck scale, and plays the role of converting the weight value into corresponding measurable electrical signals, and the advantages and disadvantages of the weighing sensor are directly related to the quality of the whole weighing apparatus.
