Request Feature Sheet


Rotadata's Around the Shaft Digital Telemetry is typically implemented when an End of Shaft Digital 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 assembly, containing power and data coils.

Rotadata has 20 years of experience designing challenging Around the Shaft Digital Telemetry units into difficult space envelopes and harsh environmental conditions, with various component configurations.

Rotadata's Around the Shaft Digital Telemetry units are turnkey specific designs for each application. The system components usually contain 3 main elements, the rotor assembly, stator assembly and the rotor mount assembly. At Rotadata we have managed many difficult thermal growth and stress profiles and we are recognised to be the low risk supply partner for the more complex Digital Telemetry applications.
