 SERIES II – Transducer Rating 160 / 512 / 1600 / 5120 (oz-in)
Vibrac’s patented Optical Torque Transducers provide a precise method for accurate torque measurement. With over 45 years of successful field application, Vibrac Transducers have consistently proven their extreme durability and reliability. The Transducers operate by shuttering light proportionally to the angular displacement of a torsion bar. This technique results in clean, noise free electrical output. The levels of these outputs are orders of magnitude greater than those of conventional transducers. By using precise encoder type discs, instead of brushes and slip rings, the Transducers are well known to have a very long life and very low inertia. Vibrac Transducers can be used for both dynamic and static torque measurement over a wide range of torque and speed. A 100% overload capability prevents permanent damage in accidental high-torque situations. The Transducers used in conjunction with any of Vibrac’s instrument packages are calibrated for zero and span with a single adjustment.
