Abstract
A torsional sensor including a high-pressure sealing mechanism for sensing at least one parameter of a high-pressure fluid. The torsional sensor includes a torsional portion including a torsional rod sensor, a reference portion coupled to the torsional portion and including a transducer device and a high-pressure sealing mechanism coupled to the reference portion and the torsional portion and in sealing arrangement therewith. The high-pressure sealing mechanism is configured to provide for sealing therein the transducer device and allow for protrusion therethrough of a torsional rod sensor. At least a portion of the torsional sensor is mountable for immersion in the high-pressure fluid and operable to propagate a torsional wave that interacts with the high-pressure fluid along the at least portion of the torsional sensor so as to affect propagation of the torsional wave in a manner dependent on the at least one parameter of the high-pressure fluid.
