Transmission of Signal Data from High Speed Machines
Edward S. Shepard · IRE Transactions on Industrial Electronics · 1958
This paper deals with the development of a completely transistorized and encapsulated telemetering device capable of transmitting signal data from high-speed machines at speeds up to 54,000 rpm. The need for this type of telemetering arose from the simple fact that in many instances it was not convenient to install contacting devices of a permanent nature on certain types of turbine machinery and the like, due to space limitations and limitations in the maximum number of information channels.
