Steps Toward High-Precision Torque Measurement

Rising fuel prices, coupled with tightening regulations on vehicle efficiency and emissions, are creating a global demand for higher levels of precision in torque measurement on test stands for engines and transmissions. On one hand, torque values must be certifiable to meet regulations and manufacturers' specs. On the other, they must be precise enough to pick up efficiency differences of 0.1% or less in the test object. Such tight system accuracy requirements mean that the torque flanges themselves must be accurate to within 0.05%.
