What is Rotary Telemetry ? When engineers and scientists need to measure torque, strain, temperature or other physical quantities on rotating shafts or components, rotary telemetry systems provide both conditioning for the shaft mounted transducers and a non-contacting means of transmitting measurement data to stationary recording and data processing equipment. A miniature transmitter and power pickup loop or battery pack are attached to the rotating shaft or component. The transmitter converts the transducer outputs into a form, which enables transfer from the rotating shaft to a stationary pickup. Transmission options include inductive, infra-red, radio and capacitive. A pickup, combined with an energising head in the case of inductively powered systems, collects the data and re-transmits via cable to the system demodulator and readout. The received data is decoded into analogue voltage or current form, or alternatively converted to serial data for input into a PC. Various configurations of demodulator / readout are available, including benchtop, industrial and compact versions for in-vehicle use For more information, contact ASTECH ELECTRONICS LTD. __________________________________________________ For details of Rotary Telemetry System Suppliers, click here...
