ABSTRACT:
A weighing device for fluent materials, for example grain, enables a flow of the material to be weighed.
The device includes a sensor member with an inclined surface over which the flow passes. The member is supported in cantilever and the force on the member due to the flow of material is sensed by sensing means.
The sensing means senses the bending forces, or other physical characteristic of the member at two positions along the member and the resulting signals are compared to give an output signal corresponding to the weight of material passing over the member.
The sensing means may be strain gauges arranged in a Wheatstone bridge circuit the output from which is passed to integrating means.
