  • Method and apparatus for retrofitting an existing conveyor to include a factory calibrated weighing device
    Patent number: 6693244
    Abstract: An integrated element scale is provided that can replace an existing support structure within a piece of equipment to achieve a piece of equipment with the integrated scale. The integrated element scale may contain one or more load cells and be configured to replace a standard component used in the assembly of certain types of equipment. The integrated element may include a mechanism to align the load portion and support portion of the element with the load cell or load cells in between them. The integrated element may further include a mechanism for protecting the load cells from damage due to overload or under load as well as side impacts. When higher accuracy is required, the integrated element further may include a mechanism for decoupling the loads within each element from other load cells within the same element or other elements so that horizontal loading between the deflecting load cells does not occur.
