FOR IMMEDIATE RELEASE
Real World Torque Measurement Accuracy
S. Himmelstein and Company Bearingless Digital Torque Transducers are designed for difficult oil field conditions. They provide high accuracy, overrange and overload. They are simple to install and extremely tolerant of rotor-to-stator misalignments.
The latest models offer best combined non-linearity and hysteresis error of less than ±0.01% of full scale. Coupled with the many standard critical features of these units, the result is a sensor that delivers the best possible torque measurement accuracy, even under varying real world conditions.
Standard features include high mechanical overloads of either 200% or 400%, depending on model, offering a mechanical safety margin in the presence of high startup torques or large torsional oscillations. Substantial overrange of up to 300% on the electrical output signals avoids clipping of real-world torque peaks and driveline torsionals and reduces potential for errors in the average torque measurement. An extremely stiff sensor element design yields the widest installed bandwidth and fastest installed response over any competitive model. Wide allowable tolerance in 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. They are available in three accuracy grades: ±0.04%, ±0.02% or ±0.01% of full scale combined linearity and hysteresis, and have world class temperature performance. These characteristics permit optimal sizing and selection of the sensor to provide the best accuracy in actual testing conditions.
All torque transducers from S. Himmelstein and Company are noise-hardened against electromagnetic interference (EMI) commonly generated by other Variable Frequency Drives, ISM transmitters and other industrial noise sources, further enhancing their real world performance.
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. All units are shipped with an NIST traceable, ISO 17025 accredited calibration certificate. Laboratory accreditation provided by NVLAP (NVLAP Lab Code 200487-0).
