<p>A process parameter sensor (5) for a material processing system (1) includes a conduit (103A-103B) configured to contain material from the material processing system. A plurality of motion transducers (105A-105D) is operative to produce a plurality of motion signals representing motion at a number of locations on the conduit. An overdetermined process parameter estimator (30) is responsive to the plurality of motion transducers and configured to receive the plurality of motion signals. The overdetermined process parameter estimator is operative to resolve conduit motion into motion attributable to each of a predetermined number of forces and to estimate a process parameter associated with a material in the conduit according to the resolved motion, wherein the number of locations exceeds the number of forces such that the plurality of motion signals provides an overdetermined information set for resolution of conduit motion into motion attributable to the predetermined number of forces.</p> |
