专利汇可以提供Transducer installation专利检索，专利查询，专利分析的服务。并且A transducer assembly holder is mounted through the wall of a fluid conveying structure and includes an acoustic window in communication with the fluid. A transducer assembly is positioned within the holder and has a transducer active element encapsulated in an elastomeric material. The assembly is positioned up against the window of the holder and a spring force is applied to the assembly through a spacer tube or rod. The arrangement is such that the spring force is transferred evenly over the encapsulating elastomeric material and a pressure bond is created between the transducer active element and the acoustic window, such couplings being essential for proper transducer operation.，下面是Transducer installation专利的具体信息内容。

9. Apparatus according to claim 8 wherein: A. said force transmittal means includes a spacer member extending between said spring and said transducer assembly.
10. Apparatus according to claim 8 wherein: A. said adjustment screw is positioned within said transducer assembly holder at the second end thereof.
11. Apparatus according to claim 3 wherein: A. said window is an integral end oF said transducer assembly holder.
12. Apparatus according to claim 3 wherein: A. said window is inserted and retained at the first end of said transducer assembly holder.
13. Apparatus according to claim 3 wherein: A. said transducer assembly holder extends through an aperture in a wall of said fluid handling structure and is in direct communication with said fluid; and B. said transducer assembly holder is secured to said wall from the outside thereof.
14. Apparatus according to claim 13 which includes: A. sealing means for preventing fluid within said structure from discharging to the outside, through said aperture in said wall.
15. Apparatus according to claim 3 wherein: A. said acoustic energy transfer is generally along an acoustic axis; B. said elongated transducer assembly holder has a central longitudinal axis; and C. said acoustic axis and said longitudinal axis being colinear.
16. Apparatus according to claim 3 wherein: A. said acoustic energy transfer is generally along an acoustic axis; B. said elongated transducer assembly holder has a central longitudinal axis; and C. said acoustic axis and said longitudinal axis being at an angle theta , where 180*> theta .
17. Apparatus according to claim 16 wherein: A. said force transmittal means includes a spacer member having a beveled head portion for urging said transducer assembly against said window when said spacer member is axially moved.
18. Apparatus according to claim 4 wherein: A. said elastomeric encapsulant contacts said backing means.
