Rotating Torque Transducers, Simple Installation and High Accuracy

S. Himmelstein: Series MCRT® 81008V Bearingless Digital Torque Transducers offer high measurement accuracy, fast installed response, high mechanical overload and electrical overrange and ease of installation. Output signals are provided as analog, digital and FM, simultaneously.

Wide allowable tolerance of the positioning of the stator relative to the rotor simplifies the user’s installation and protects the equipment from rotor to stator contact due to vibration or thermal growth. Mounting pilots and bolt circles are dimensioned in SI units, fasteners are metric.

They are available in three accuracy grades: ±0.1%, ±0.05% or ±0.03% of full scale combined non-linearity and hysteresis, and have world class temperature performance. Mechanical overload of 200% offers a safety margin in the presence of high startup torques or large torsional oscillations. Electrical overrange of 150% avoids clipping of real world torque peaks and driveline torsionals reducing potential for errors in the average torque measurement. A carrier amplifier, immune to dc and low frequency signals, conditions the strain gage torque bridge output. An extremely stiff sensor element design yields wide installed bandwidth and fast response to torsional transients.

Each is easy to use with included interface software that allows fast PC setup and re-configuration while selecting from up to 10 units of measure, all without re-calibrating. All are calibrated CW and CCW to rated load in our ISO 17025, NVLAP accredited laboratory (NVLAP lab code 200487-0).

They are well suited for a broad range of applications including both performance and endurance testing of engines, transmissions, drive systems, pumps, motors, servo motors, gearboxes, actuators, etc.

S. Himmelstein and Company has been offering innovative torque measurement solutions since 1960, manufacturing a full line of shaft, spline, flange, pulley, wheel and reaction torquemeters, and other torque measuring instruments. For more information, call 1-800-632-7873, visit www.himmelstein.com.
