Rotary Torque Transducers

Drawing on more than 50 years of experience and innovation, S. Himmelstein and Company builds rotary torque transducers that give the highest accuracy in real-world environments.

  • Ultra-Precise Digital — Three overload models plus dual-range model, torque ranges: 25 to 375,000 lbf-in.

  • Low Capacity — Shaft-end models, torque ranges: 10 to 400 ozf-in.

  • Precision Digital — Three overload models plus dual-range model, torque ranges: 25 to 4,000,000 lbf-in, .05 percent accurate analog of shaft torque, .02 percent noise and ripple.

  • Bearingless Digital — Flanged/Disk-style, very high stiffness, easy installation, tolerant of rotor-stator misalignment. Ranges from 250 to 4,000,000 lbf-in.

  • MV/V Analog — Torque ranges: 25 to 4,000,000 lbf-in, mV/V output, compatible with ac carrier amplifiers.

  • DC Analog — Torque ranges 10 lbf-in to 4,000,000 lbf-in.

Rotary Torque Transducer

Rotary torque transducers: measure torque in a rotating shaft and sense torque with high-precision strain gages. These respond to shear forces with changing electrical resistance when mounted on a rotating element. When configured in a Wheatstone Bridge arrangement, sophisticated electronics convert these signals into torque values. In both cylindrical and pancake configurations, the rotary transformer offers advantages over slip rings: they offer no friction, no wear, are immune to intermittent contact problems, and can operate at higher speeds.
