A digital balance scale is essentially a balance scale equipped with electronic calculating and reading technology. Recent trends are shifting to digital load cell technology. Analog converters, networking systems and sophisticated fiber optic technology are often integrated directly into the load cell, increasing the precision and accuracy of measurements. The load cell measures and determines an analog value, which is converted by a circuit board into a precise digital number which is then transferred directly to the display screen. Digital balance scales feature alpha-numeric display panels, a touch-sensitive keypad that allows for precise entry of information and adjustable environmental filter settings that can adjust balance according to various environmental conditions. Most digital balance scales contain multiple weighing units, allowing a degree of flexibility of weighing in industrial and commercial operations. Large manufacturing companies use digital balance scales equipped with a parts counting function, used for accurate tabulation of small parts and components. A capacity tracking feature shows a graphic-type digital display of the used and unused portions of the weighing range. This feature is important in determining container weights loaded with different components. The directional interface feature provides communication between data collection and printing instruments. Adjustable feet can be attached to maintain level balance for accurate measurements on uneven working surfaces, such as in mining or construction operations.
Digital balance scales are the measurement instrument preferred by transportation and logistic companies, including air cargo transport and trucking industries. Heavy duty industrial digital balance scales are used in the railroad transportation industry, as rail cars can be accurately weighed in static or motion applications. Unlike traditional spring scales, the accuracy of digital balance scales may be electronically compensated for the variations in local gravitational forces, which can vary at different locations on the earth. A slight variation in the strength of the gravitational field caused by movement of the digital balance scale will not alter the measured mass because the forces on each side of the balance beam are equally affected. High precision digital balance scales, while highly efficient, can be affected in outdoor applications by air gusts, buoyancy, friction condensation, evaporation or changes in magnetic fields.
Most recently, new ultra precision Surface Acoustic Wave Scales (SAW Scales) offer a truly digital load cell output. They do not require the analog to digital conversion required for standard load cells. The accuracy is also up to ten times higher than regular scales.
