Test rig technology talks the torque

摘要

TO analyse the long-term performance and reliability of hard-working valves and pumps, the Bifold Group has adopted radio frequency-based torque transducers from Sensor Technology for two of its specialist test rigs. When It wanted to assess the effects of wear on its long-life valves it set about designing a special test rig. Engineer Andrew Laverick recalls: "We wanted to measure the power required to operate the valve to see how it changed over time and with long-term use. It was clear that the best way to do this was to measure the torque input over an extended period.
