Accumetrics' comprehensive line of telemetry products includes battery and induction powered telemetry systems to meet the most demanding wireless torque, force, and strain measurement applications in a wide variety of industries from automotive to wind power to rolling mills and more. Our telemetry systems wirelessly and safely transmit real-time measurement data off of rotating shafts, including shafts rotating at high RPM.
How can Accumetrics solve your measurement challenges?
Accumetrics' single channel systems are ideal for torque, temperature (thermocouple and RTD), and electrical measurements on drive shafts of motor-generators. These solutions serve as a rugged and non-contact alternative to slip rings.
Need to perform torsion testing or take measurements on rotating shafts for a temporary application or in small spaces? Accumetrics' battery powered digital telemetry system, AT-5000 EasyApp is mounted to a shaft using a heavy-duty aramid fiber strap. Measure, digitize, and transmit data wirelessly off rotating half shafts, drive shafts, and rotors to a stationary receiver. The receiver converts the digital data to an analog output voltage.

Battery Powered Telemetry System for Short-Term Testing
Need to take precise measurements on rotating shafts over a longer duration? Accumetrics offers induction powered solutions ideal for long duration applications where accuracy, resolution, low drift, and low noise levels are critical. The induction power eliminates the need for batteries. Sensor data is directly measured and digitized on a rotating shaft then transmitted off-shaft using wireless technology. The receiver outputs high bandwidth analog data.

Induction Powered Telemetry for Permanent Installations
When using slip rings for measurement, there is contact between the shaft and a stator which can cause:
With wireless telemetry, there are no parts that rub against the shaft and wear out.
