S. Himmelstein and Company’s Bearingless Digital Torque Transducers measure torque with high accuracy. They are available with a best combined non-linearity and hysteresis error of less than ±0.01% full scale. The Bearingless torque sensor is simple to install, and users can select from 10 units of measurement without recalibration. It comes in capacities from 5Nm to 2.5 million Nm. Dual-range units are also available.
Standard features include high mechanical overloads of 200% or 400%, offering a mechanical safety margin in the presence of high startup torques or large torsional oscillations. Substantial over-range of 150% to 300% on the electrical output signals avoids clipping of real-world torque peaks and driveline torsionals, reducing the potential for errors in the average torque measurement. 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 are calibrated CW and CCW to rated load in S. Himmelstein and Company’s ISO 17025, NVLAP-accredited laboratory (NVLAP lab code 200487-0).
