Around the Shaft telemetry is only implemented when End of Shaft Telemetry unit cannot be used due to shaft end restrictions. It consists of an annular rotor which is mounted at a location along the test vehicle's rotating shaft, to a suitable rotating interface and a stator assemly, containing power and data coils. Rotadata have over 20 years of experience designing challenging Around the Shaft telemetry units into difficult space envelopes and harsh environmental conditions, all with varying capabilities.
All Around the Shaft telemetry units are bespoke designs for each application, but the system components usually contain the following elements:
|Rotor Assembly||Electronic Casette assemblies Annular interconnect PCBs Power and data transmission coils|
|Stator Assembly||Stator Body Power and data transmission coils Test vehicle stationary interface|
|Rotor Mount and Connector Assembly||Rotor mounting hardware Instrument termination PCB Test vehicle rotating interface|
