To combine weigh in the most accurate portion, a combination weigher—whether a linear combination weigher or a multi head combination weigher—uses several combination scales to measure product portions simultaneously. The system then runs a rapid algorithm to find the optimal sum closest to the target weight. This process, known as combination calculation weighing, ensures speed and accuracy. Curious how a multi head weigher calculates combinations? It evaluates hundreds of combinations per second and selects the best-fitting one for each cycle.
