Ridgetop Group’s RotoSense advanced rotational vibration sensor 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 for industrial applications.
RotoSense utilizes a low-power system architecture based on the Internet-of-Things (IoT) to help engineers perform wireless vibration analysis of rotating equipment and machinery. RotoSense is available in different packages for a range of applications. In addition, data from this innovative instrument can be used with a library of Sentinel Motion algorithms that extract prognostic feature data as a means to perform condition-based maintenance (CBM). The result is an improvement in safety, performance, and maintenance costs for future generations of rotating components.
Data is logged and compared in real time between the local testbed and a remotely located wireless gateway with precise results.
The latest update to RotoSense includes Sentinel MotionView, enabling faster setup for field analysis. Go to the Apple Store and download Sentinel MotionView on your IOS device today.
Standard RotoSense form factors are available by purchasing a Sentinel Motion Development Kit (SMDK), and can even be customized for unique industrial IOT applications. The RotoSense wireless vibration and temperature 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. Additional applications are listed below:
- 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
