Ridgetop Group’s RotoSense advanced rotational vibration sensor (RVS) enables easy extraction of high-resolution acoustic signatures from rotating components in harsh environments. RotoSense is included in the Sentinel Motion™ product line of advanced diagnostic and prognostic tools, and is an integral part of the RailSafe™ Integrity Analysis System.
Ridgetop’s innovative Internet of Things (IoT)-compatible RotoSense wireless instrument helps engineers perform dynamic analysis of rotating interaction and develop improved designs for rotating components. RotoSense is available in different packages for a range of applications. In addition, data from this instrument can be used with Sentinel Motion algorithms that detect and predict faults based on external acoustic signatures, for prognostic purposes. The result is an improvement in safety, performance, and maintenance costs for future generations of rotating components.
The RotoSense wireless rotation sensors have been installed and tested inside a Bell OH-58 helicopter gearbox spinning at 5,500 RPM. A paper jointly authored by NASA and Ridgetop Group details the impressive results. RotoSense has also been tested on the Transportation Technology Center, Inc. (TTCI) test track in Pueblo, Colorado.
Data are logged and compared in real time between the local testbed and a remotely located wireless gateway with precise results.
- Sensing gear tooth wear, chatter, or spindle balance in computer numerical control (CNC) applications
- Real-time monitoring of downhole drill vibration in oil and gas exploration applications
- Detecting vibrational signatures in rotating shafts or pinions to give early warning of gear tooth cracking or spalling in wind turbines and transmissions
- Sensing wheel cracks, friction, and wear in train applications
RotoSense development kits are available from Ridgetop.
