A pointer (called also tilt scale) measures by a fixed weight on a single lever arm rash, this mechanism is used for postal scales. One Scale, consisting of a rod with a scale and two unequal levers, one equipped with a counterweight, the other with the hook to attach the material to weigh is also quite common. The ratio between the two arms is carried out by the moving of the attached weight. A Dezimalwaage is similar to the principle of the scale, the really striking difference here is the arm length ratio of ten to one for the weight lifting arm. So you can weigh out relatively precisely up to ten times that with the help of reference weights.
Examples of scales with weight force comparison principle; Scales and kitchen scales, baby scales, up to 5 or 10 kg General function according to the principle of the spring scale. Scales as there are in every household that measure the weight of the body (usually up to 150 kg, with a deviation of up to 3 kg). Mainly stand-alone machines for the trade or industry (with different scale divisions, divided into 25 kg / 50 g, 50 kg / 100 g or 100 kg / 200 g, with a minimum Deviation which is specified here as a percentage and is located under one per cent). Electromechanical – and electronic scales the advance of electronic weighing scales provides the associated benefits, such as their robustness, precision and easier readability to a maximum displacement of previously related mechanical scales. In particular, the cost advantage achieved through innovative technology in the production ensures that electronic scales are usually even cheaper to purchase than mechanical scales. Its possible construction, such as for example a protective air movement chassis, special damping devices to reduce vibrations normally also provide reduced susceptibility and thus a higher service life.
The setting of modern scales can be refined, which is another advantage over the usual mechanical devices by means of program calibration. The normal range is in terms of kilograms with an average deviation of maximum 0.15%. Functioning electronic scales; The Forming the weight in a way, or a kind of deformation is necessary for all electronic weighing scales, as these only indirectly measure can be. This transformation can generate itself through a spring or a bending beam, whose size and solidity is crucial later for the mass deliberative off to, so the spring supplied in a crane scale is an almost solid block of E.g. metal. The measurement of the deformation of the beam, or the spring can be done either directly through a stretch marks or indirectly through the encoder, where, for example, the change in the capacitance of a capacitor can be measured by the resulting plate spacing. Examples of electro-mechanical scales; Crane scales with a measuring range of up to 200 tons of static / dynamic axle load scales (weight was determined ultimately by summing the individual weighing of individual axles of a vehicle) platform and vehicle scales (E.g. weighbridges) floor scales, pallet scales the technique for the given scales related works basically after the above sensor principles, namely the principle of electromechanical power compensation and the Wagezellenprinzip (with stretch marks).
