Telemetry

RTM GmbH telemetry systems provide a means of accurately transmitting signals from a moving or rotating component. The strain, thermocouple or voltage signals are conditioned and transmitted completely wireless from the rotating antenna to the stator and then to the control unit. The control unit converts the transmitted signal back to an analog value. This data can be read on the control unit display and can be connected to an external data acquisition system. The system can be powered by a battery on the rotating side or inductively powered from the standard stator. The inductive powered installation can provide a completely maintenance free operation for many years. The compact and lightweight design of the rotor electronics makes the system ideal for limited space installations without influencing the dynamic properties of the component under test. The “one winding” technology allows for quick and easy installations where the power is transmitted to the rotor electronics and the conditioned signal is transmitted back through the same antenna. This flat antenna band permits a generous axial and radial distance between the stator and the moving part. The telemetry systems offer a remote shunt calibration feature which allow strain gage applications to be verified even during measurement.
