S. Himmelstein and Company (Hoffman Estates, IL) introduces its Bearingless Digital Torque Transducers. Designed for difficult conditions, they provide high accuracy, overrange and overload. According to the company, the latest MCRT 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. Other 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.
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.
