Claims
- 1. An apparatus for transmitting both emf and pneumatic signals from a high speed rotating test item, said test item mounted in a test fixture, said apparatus comprising:
- means for selectively connecting one of a plurality of rotating pressure tubes to a single rotating pressure. A tube, the pressure present in said one of said plurality being input into said single rotating pressure tube;
- slipring means for converting a plurality of rotating sensor wires connected to said rotating test item to a plurality of stationary output wires having thereon said emf signals, said slipring means having therein a longitudinal void, said single rotating pressure tube for output passing through said void;
- a pressure transducer, said pressure transducer being stationary, said pressure transducer having input said single rotating pressure tube and having output a stationary pressure sensor wire having thereon a pneumatic signal indicative of the pressure in said single rotating pressure tube;
- a shaft connected to said test item and containing said means for selecively connecting and said slipring means fixedly mounted to said shaft rotatably secured within said test fixture, and
- a case, said case having said shaft rotatably secured thereon and said pressure transducer fixedly secured thereon, said case being stationary.
