Single Channel Telemetry | Measurements from Rotating Shafts

Measure Torque, Strain, Temperature, Force, Vibration, Voltage

Accumetrics' telemetry products 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.

Safe, Reliable, Non-Contact Torque and Strain Measurements Even at High Rotational Speed

How can Accumetrics solve your measurement challenges?

  • Speed | Measurements transmitted from shafts rotating at speeds as high as 17,000 RPM
  • Reliability | High data integrity and noise immunity: No interference seen from ignition, variable frequency motors, drills, etc.
  • Ruggedness | Stands up to harsh environments
  • Safety | Tired of tape? Equipment is securely fastened to the shaft with a split clamp collar
  • Ease of Installation | With split clamp collars, installation is quick and simple, in some cases taking as little as 5-10 minutes
  • Support | Accumetrics' commitment to Total Customer Satisfaction (TCS) ensures you'll get the support you need to 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.

 

Induction Powered Non-Contact Measurement Transmission

Need to take precise measurements on rotating shafts over a longer duration? Accumetrics offers an induction powered solution 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.

Why Use Telemetry as a Replacement for Slip Rings?

When using slip rings for measurement, there is contact between the shaft and a stator which can cause:

  • Reliability issues
  • Maintenance difficulties
  • Brushes to wear out, requiring replacements

With wireless telemetry, there are no parts that rub against the shaft and wear out.
