Abstract
A transducer baseplate includes a base, a protrusion extending from the base along a longitudinal axis, a pair of opposed transducer receptacles defined within the protrusion, and respective pressure plena. The pressure plena are separated by a plenum wall, each plenum being in fluid connection with an area external to the protrusion through a respective pressure line. The pressure lines provide a direct fluid path to their respective receptacles.
Claims13
A transducer baseplate comprising:
- a base with a protrusion extending from the base along a longitudinal axis, wherein the base has a cross-sectional perimeter in a plane perpendicular to the longitudinal axis;
- a pair of transducer receptacles defined within the protrusion, wherein the transducer receptacles are opposed from one another across the longitudinal axis, wherein the transducer receptacles are in fluid and operational isolation from one another, wherein the receptacles each have a width parallel to the longitudinal axis, and wherein the combined widths of the receptacles, when oriented in a common plane perpendicular to the longitudinal axis, are too large to fit within the cross-sectional perimeter of the base;
- and
- a pair of pressure plena separated by a plenum wall, one plenum in fluid communication with each receptacle, respectively, wherein the pressure plena are in fluid and operational isolation from one another within the protrusion, wherein each plenum is in fluid connection with an area external to the protrusion through a respective pressure line, and wherein the pressure lines provide a direct fluid path to their respective receptacles.
