Beltweigher

[1] Invented by Herbert Merrick in the early 1900's, belt weighers are commonly used in plants and heavy industries, such as mining.

[2] Belt weighers replace a short section of the support mechanism of the belt, which might be one or more sets of idler rollers, or a short section of channel or plate.

This weighed support is mounted on load cells, either pivoted, counterbalanced or not, or fully suspended.

[3] Belt weighers generally include the necessary electronics to perform this calculation, often in the form of a small industrialized microprocessor system.

Due to the belt tension variation, frequent check calibration must be done.
