SAW Torque Transducers Offer Wide Measurement Range

The TorqSense RWT320 series digital, configurable non-contact SAW rotary torque transducers are available in versions from 500 mNm to 10,000 Nm. The component interfaces with LabVIEW-based software to indicate the torque, speed, power, and peak torque of rotating drive systems. Employing surface acoustic wave and patented TorqSense technologies, it promises precise measurement of the strain-induced resonant frequency change in frequency-dependent, internal surface acoustic wave devices without loading the drive with extra inertial load. Other features include user-selectable features, digital outputs, diagnostics, the ability to monitor and output shaft temperatures, an accuracy to ±0.25% FS, and a resolution of 0.1% FS. Price for the RWT320 is $1,800 each. SAELIG CO., Pittsford, NY. (888) 772-3544.
