The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A mounting system for supporting a precision transducer in spaced alignment with a supporting case, the mounting system comprising a plurality of mounting means, each mounting means having first and second ends and a resilient intermediate portion, the first end of each mounting means being connected to the transducer, the second end of each mounting means being connected to the case, at least the first end being composed of a substance that has a coefficient of thermal expansion approximately equal to the coefficient of thermal expansion of the transducer, the intermediate portion of each mounting means being adapted to provide a low resistance to relative movement between the transducer and case in a radial direction and a high resistance to relative movement between the transducer and case in directions normal to the radial direction, whereby differential thermal expansion or contraction between the transducer and case do not stress the transducer or cause misalignment between the transducer and the case.

2. The mounting system of Claim 1, wherein the first ends of adjacent mounting means are joined to one another by means of bridge sections, such that the mounting means and bridge sections form a continuous, mounting ring, the bridge sections being composed of a substance having a coefficient of thermal expansion approximately equal to the coefficient of thermal expansion of the transducer.

3. The mounting system of Claim 2, wherein each intermediate portion comprises a beam having one compliant axis and two noncompliant axes normal to each other and to the compliant axis, each beam having its compliant axis oriented in the radial direction.

4. The mounting system of Claim 3, wherein the transducer is generally cylindrical in shape, wherein the compliant axis of each beam intersects the centerline of the transducer, and wherein the length dimension of each beam is aligned with the cylindrical axis of the transducer.

5. The mounting system of Claim 4, wherein the first ends and the bridge sections form a continuous, cylindrical, inwardly facing mounting

surface, and wherein the mounting ring is connected to the transducer at said mounting surface.

6*. The mounting system of Claim 5, wherein the transducer includes a cylindrical mounting section, wherein the mounting ring is connected to the transducer at said mounting section, and wherein the mounting section and the mounting ring are composed of the same substance.

7. The mounting system of Claim 6, wherein said substance is

Invar.

8. The mounting system of Claim 6, wherein the mounting ring is connected to the mounting section by welding.

9. The mounting system of Claim 3, wherein the width and length of each beam are substantially greater than the thickness of the beam such that the compliant axis of the beam corresponds to the thickness dimension, and wherein the thickness dimension of the beam is aligned with the radial direction, whereby the beam has a relatively small resistance to differential thermal expansion between the transducer and the case, and a high resistance to overall translation and rotation of the transducer with respect to the case.

10. The mounting system of Claim 2, wherein the second ends of adjacent mounting means are separated from one another by gaps.

11. The mounting system of Claim 10, wherein the second end of each mounting means is connected to the case by means of an adhesive.
