Scale is widely used in industry, agriculture, commerce, scientific research, health care and other sectors. Weighing scale is the use of Hooke's law or force lever balance principle to determine the mass of the object. So do you know what scales include?
1, car scale
Car scale, also known as weighbridge, is the main weighing equipment used in factories, mines, merchants, etc. for bulk cargo measurement. In the twentieth century before the 1980s common car scale is also known as mechanical weighbridge. In the mid-1980s, with the increasing maturity of high-precision load cell technology, the mechanical weighbridge was gradually replaced by high-precision, stable and easy-to-operate electronic weighbridges.
2, electronic crane scale
Electronic crane scale is to make the object in the hanging state for its quality (weight) measurement of electronic scales, called electronic crane scale. Requirements for the use of the occasion must have an electric hoist, generally used in steel mills, coil mills, steel mills, docks and other areas.
3, electronic forklift scales
Electronic forklift scales are particularly suitable for railroads, highways, trade, industry and mining, and other logistics operations in the weighing of goods, scales by the hydraulic manual handling mechanism and weighing components, hydraulic drive platform lift, manually implement the vehicle running.
4, electronic platform scales
Electronic platform scales are more common, there is a separate load weighing platform and connected to the column mounted weighing display instrument. Working principle: electronic platform scale is the use of electronic strain elements deformation principle of force output small analog electrical signals, through the signal cable to the weighing display instrument, weighing operation and display weighing results. The electronic platform scale has various display modes: digital tube display [LED], liquid crystal display [LCD], luminous display [VFD] and liquid crystal point vibration display. The platform is fitted with an overload protection device to protect the load cell [against extreme overload]. The weighing range of the electronic platform scale is around 30-600kg.
2. What is the structural composition of the scale
The scale mainly consists of 3 parts: load-bearing system, force-transferring and converting system, and indication system.
1. The load-bearing system (e.g., the weighing pan)
The structure depends on the form of the object being weighed. Platform scales, weighing scales are generally equipped with a flat plate load-bearing mechanism; specializing in the measurement of an object scales, is equipped with a special load-bearing mechanism to shorten the measurement time and reduce the operation of the heavy weight, the load-bearing system, although the structure is different, but the function is the same.
2, force transmission system (such as lever force transmission system)
is the key component that determines the measurement performance of the scale. Usually use lever force transfer system and deformation force transfer system. Lever transmission system mainly consists of load-bearing levers, transmission levers, bracket parts and linkage parts such as knives, knives, hooks, rings and so on.
3, the value system (such as dial)
Mechanical scales of the value system is mainly used with a scale marking the measurement of the lever or dial. The former use to increase the weight, swimming weights, weights to balance the measuring lever to obtain readings; the latter through the pointer along the fan or circular dial rotation to indicate the results of measurement. Electronic scale value system for the weight indicator, it has a digital display and analog scale display two kinds.
