At the messtec + sensor masters 2018 trade show, the Dx-Power system took first place in the sensor category and won the coveted messtec + sensor masters award. It was recognized as an innovative system for non-contact power measurements on vehicles that does not require any additional mechanical connection for rotation angle detection.
The Dx-Speed system conveniently acquires the wheel speed directly on vehicle wheels. The system does not require a stator or additional reference point and delivers measurement results – both on the test bench and outdoors – even in harsh conditions such as mud, snow and dust. The accouracy ist typically better than 0.5%. Impacts against the axle also will not affect the results. This means that even driving over sleepers is possible!
The Dx-telemetry system is universally applicable. With a receiving unit (Dx-RCI), data from up to four transmission units (Dx-SCT) can be received synchronously. Each Dx–SCT sends data from one or more different sensors to the Dx–RCI. It is therefore easy to cascade an already existing system.
In automotive development, it is important to accurately measure the torque exerted by the vehicle – especially during acceleration and braking maneuvers. The WTT-D<sup>x</sup> provides users with a highly precise tool. The measuring wheel detects the mechanical load directly where it is generated: at the wheels, the meeting point between vehicle and road.
A highlight of CAEMAX´s new, fully digital DX telemetry is the ability to perform absolutely synchronous data acquisition with several transmitters in one single ISM band. With one single telemetry transmitter up to six channels – e.g. two strain gauge full bridges or four half bridges or analogue signals or temperatures can be transmitted. The max. sum sampling rate is 7,2 kHz.
Whether doing dynamics tests, brake tests or determining load spectra – the new 6-Component WFT-Cx measuring wheel measures all forces and moments acting on the vehicle with high precision. The robust housing provides reliable protection against dirt, water and snow and can be used in all weathers.
For measurements on rotating components and moving machinery, imc offers modern telemetry systems for a wide variety of tasks: whether single-channel torque monitoring of a rotating shaft, multi-channel strain gauge and temperature measurements on a train wheel-set or non-contact power measurement on a vehicle drivetrain in harsh environments.
CAEMAX extends its proven Dx telemetry system with a high-temperature version for ambient temperatures from -40°C bis +125°C. This enables applications in the engine compartment, measurements in the climatic chamber and temperature-critical applications in mechanical engineering and energy technology.
