Illustrated and specified as simple to install, both instruments offer tolerance of wide rotor-stator misalignment. They deliver low sensitivity to clamping loads plus high overrange and overload. They're emphasized to "have high accuracy in real-world applications, not just in the cal lab."
Bearingless digital torquemeter features are cited to include 0.05% accuracy, 200% and 400% overload, 300% overrange, 0.0006%/°F. compensation, analog and FM outputs, plus 3 kHz signal bandwidth.
