WHAT IS CLAIMED IS:

1. A transducer sensor body comprising:

a first support structure;

a second support structure;

a tubular element having a center bore along a longitudinal axis;

a first flexure being elongated and joining the tubular element to the first support structure parallel to the longitudinal axis, the first flexure being rigid to transfer a longitudinal force therethrough along the longitudinal axis and being rigid to transfer an axial force therethrough along an axial axis that is orthogonal to the longitudinal axis; and

a second flexure being elongated and joining the tubular element to the second support structure parallel to the longitudinal axis, the second flexure being rigid to transfer a longitudinal force therethrough along the longitudinal axis and being rigid to transfer the axial force therethrough along the axial axis.

2. The transducer sensor body of claim 1 wherein the first and second flexures are compliant to a translational force along a translational axis that is mutually orthogonal to the axial axis and the longitudinal axis.

3. The transducer sensor body of claim 2 wherein the second flexure is disposed on a side of the tubular element opposite the first flexure.

4. The transducer sensor body of claim 3 wherein the first flexure and the second flexure are mirror images of each other with respect to the longitudinal axis.

5. The transducer sensor body of claim 1 and further comprising:

a second tubular element spaced apart from the tubular element having a second center bore along a second longitudinal axis;

a third flexure being elongated and joining the second tubular element to the first support structure parallel to the second longitudinal axis, the third flexure being rigid to transfer a longitudinal force therethrough along the longitudinal axis and being rigid to transfer the axial force therethrough along the axial axis; and

a fourth flexure being elongated and joining the second tubular element to the second support structure parallel to the second longitudinal axis, the second flexure being rigid to transfer a longitudinal force therethrough along the longitudinal axis and being rigid to transfer the axial force therethrough along the axial axis.

6. The transducer sensor body of claim 5 wherein the longitudinal axis and the second longitudinal axis are aligned with each other along a common longitudinal axis.

7. The transducer sensor body of claim 6 wherein the first, second, third and fourth flexures are compliant to a translational force along a translational axis that is mutually orthogonal to the axial axis and the longitudinal axis.

8. The transducer sensor body of claim 5 wherein the third flexure is disposed on a side of the tubular element opposite the fourth flexure.
