LORD Sensing’s Torque-Link has been used successfully by several companies in flight test applications. Instead of relying on bulky, unreliable slip rings that require hours to install, engineers were able to quickly install Torque-Link nodes and connect it to a wireless system for fast and accurate torsional strain measures.
The limitations of slip rings is perhaps most apparent on the proving grounds for off-highway vehicles. During development tests, slip rings may last only 100-200 hours before failure, while the Torque-Link wireless node has been proven to endure for more than 1,000 hours. In addition, removing a failed slip ring may require several hours. A Torque-Link, meanwhile, requires less than five minutes for removal, battery replacement, and re-installation.
Rotating Machinery Analysis:
Engineers performing root-cause analysis for rotating machinery failures use the Torque-Link in burst mode (up to 4 kHz) due the higher frequency required for analysis of torsional vibration and driveline resonance. In the field, a system of more than ten Torque-Links has been used by a company to analyze how driveline resonance caused driveshaft failures on fracking pump trucks. LORD Sensing’s Torque-Link technology successfully analyzed the situation and provided a damping solution.
Many companies currently rely on accelerometers and thermocouples to measure bearing vibration, pump vibration, machinery vibration, and temperature. Using a LORD Sensing Torque-Link not only accomplishes the same goals but also increases accuracy and can also identify other issues-- helping to more fully diagnose failures and plan maintenance cycles, which can, in turn, save up to $1 million per hour that would have been lost during unplanned maintenance downtime.
