Abstract
A slip ring includes a rotor and a stator. Stator contacts are connected to a data acquisition unit. The rotor contacts are connected to an amplifier circuit mounted in a housing connected to and rotatable with a rotating member. A sensor mounted on the rotating member to which the rotor is also fixedly mounted generates an electrical output signal corresponding to a sensed operating parameter of the rotating member. The sensor output signal is amplified by the amplifier in the housing before being transmitted through the slip ring to the data acquisition unit. Vibration isolation is provided when required for the slip ring and the circuit board in the housing carrying the amplifier to dampen vibrations generated by the rotating member. Resilient pads are mounted on the circuit board and engage the housing attached to the rotor.
