Weighing module converts mass (weight) into electricity, which is a mass (weight) measurement method. The output electric quantity signal and the input mass (weight) signal have a single-value linear correspondence, which has the required accuracy and high sensitivity, good frequency response characteristics and less inertia, has little influence on the state of the weighed object, and can work in poor environmental conditions; Good stability, reliability and long service life.
020-34563445Every time the weighing module completes the collection of weighing signals and data preprocessing, it completes the nonlinear error in the whole weighing range according to the principle of adaptive compensation. Comparison of weighing output before and after adaptive nonlinear error compensation. Is the output before and after weighing compensation
The number of metering modules is usually determined based on the number of supporting points, so that the center of gravity coincides with the geometric centers of multiple weighing sensors (supporting points). The weighing module is mainly composed of scale body, weighing sensor and weighing instrument, and the supporting part should meet the requirements of levelness, straightness, rigidity and parallelism as much as possible.
In order to realize the static weighing measurement of large containers and hoppers in industrial environment, weighing module integrates weighing sensor, load transmission device, limit and overload prevention, and can be easily connected with various mechanical equipment. On the basis of traditional resistance strain sensor, combined with modern microelectronics technology and microcomputer technology, control functions are added, including weight display, quantitative feeding, unloading, field equipment control, alarm signal display, formula setting and process monitoring.
