Horizontal sensing plate
The material travels down the flowguide, striking the sensing plate and discharging through
the outlet. The force exerted on the sensing plate has both a vertical and horizontal
component. The design of the load cell is such that it reacts to the horizontal component
only; the vertical component is ignored.
The sensing plate is displaced proportionally to the material flow and is not susceptible to
material build-up, so long as it does not bridge across to the housing. Positive displacement
of the load cell is limited by the positive stop incorporated in the design of the load cell.
The displacement of the load cell is sensed by its strain gauges. These convert the excitation
signal from the electronic integrator to produce a signal proportional to material flow.
