Calibration for S. Himmelstein Torque Transducer Products 

Calibrate Now provides NVLAP-accredited torque transducer calibration for S. Himmelstein MCRT® 84000V and 85000V bearingless digital torque transducers. Every calibration is performed in our accredited laboratory (NVLAP Lab Code 200487-0) and documented on an ISO/IEC 17025:2017 accredited, NIST-traceable certificate, so your quality team has defensible records for every audit.

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.

Himmelstein Bearingless Digital Torque Transducers offer the Best Real World Accuracy of any Torquemeter, Torque Sensor or Torque Transducer.  They feature wide installed measurement bandwidth with fast installed response, they are simple to install, tolerant of wide rotor – stator misalignments, and have the lowest sensitivity to clamping loads, highest overrange and overload.

Calibration Options for MCRT® Bearingless Transducers

Choose the calibration level that matches your quality program and how the transducer is used in your test stand.

• 10-point bi-directional calibration: the transducer is loaded at ten points in increasing and decreasing directions, CW and CCW, to characterize linearity, hysteresis, and repeatability.
• 10-point as-found/as-left calibration: two full calibrations, one as received and one after any adjustment or repair, with both data sets on your certificate for ISO 9001 and AS9100 documentation.
• Temperature and speed verification (factory calibration): available only for S. Himmelstein and Company transducers, including MCRT models. The unit is cycled from +75 to +175°F and run at maximum rated speed for 30 minutes before its 10-point calibration.

Why Calibration Matters for High-Accuracy MCRT Transducers

An MCRT transducer specified at ±0.01% of full scale only delivers that accuracy while its calibration is current. Periodic accredited torque sensor calibration confirms that linearity and hysteresis remain within the grade you selected and gives auditors documented proof that your measurement equipment is fit for purpose. If your quality program sets a calibration interval, schedule your MCRT unit before it lapses to avoid gaps in your test data.
