Principle of operation
Belt scales work with an existing belt conveyor and the selected Siemens integrator. As material
moving along the conveyor belt travels over the belt scale, it exerts a force proportional to the
material load through the suspended weighdeck to the load cells.
The belt scale reacts only to the vertical component of the applied force. The resulting
movement in each load cell is sensed by its strain gauges. When the strain gauges are excited
by voltage from the electronic integrator, they produce an electrical signal proportional to weight,
which is then returned to the integrator. The vertical movement of the load cells is limited by the
positive overload stop incorporated into the design of the belt scale.
