Abstract
A sensor (18) for measuring the rheology of materials is provided, comprising a deformable beam (20) simply supported at two locations (21 and 22). The beam has supported and unsupported portions, with the unsupported portion (28) extending beyond the supported portion. A strain gauge (23) is attached to the supported portion of the deformable beam (20), and measures the induced strain on the beam when the unsupported portion (28) is deflected by a moving material.
