Long-term Quality Assurance of Measurement Results

Professional torque transducer calibration is a prerequisite for assuring the quality of your measurement results in the long term. Moreover, torque sensor calibration is an integral part of your ISO9001 certification.

Torque Calibration at HBM: From 0.2 N·m to 400 kN·m

The HBM calibration laboratory offers many advantages when it comes to calibrating your torque transducer:

Torque calibration in the range from 0.2 N·m to 400 kN·m - an extremely wide range. HBM maintains the only private calibration laboratory worldwide that can offer you this service
Calibration of complete measuring chains (also of third-party products) - at no additional cost for you
Decades of experience (since 1977) in the calibration of torque transducers, torque sensors and torque measurement chains
From the cost-effective calibration of industrial sensors to the transfer standard that meets the highest demands
Calibration of alternating torque as a working standard calibration

Traceable

ISO 17025 certification
Direct traceability to the German National Metrology Institute (PTB)
Assessment of the calibration laboratory by independent experts at regular intervals

Benefit from calibration certificates with minimal measurement uncertainty, directly traceable to the National Standard.

Precise

Calibration machines with minimal measurement uncertainty (in non-state calibration laboratories)
Dead-load machines (sensors are loaded with weights on a lever arm in the Earth’s gravity field) up to 25 kN·m, extraordinary for a private calibration laboratory
Machine accuracy up to 0.008%
Unique competence up to 400 kN·m with a measurement uncertainty of 0.1%

Optimize your measurement uncertainty assessment using the actual transducer characteristics - instead of data sheet specifications only.

If you want to know everything about your sensor: Calibration in accordance with DIN 51309 requires measurements using the sensor in three varying mounting positions. In other words, the sensor is rotated by 120° in the machine in each case i.e. the torque transducer needs to be mounted and dismounted thrice. The following characteristics are obtained from a DIN 51309 calibration and specified in the calibration certificate:

Exact output signal for each calibration step
Hysteresis values for each calibration step
Repeatability and reproducibility for one and for varying mounting positions for each calibration step
Creep behavior
Return to zero
Interpolation error (the measured value’s potential deviation from the cubic and linear approximation).
Classification in accordance with DIN 51309

Furthermore, the calibration certificate specifies the measurement uncertainty as defined in DIN 51309. This calibration provides guaranteed proof that your torque sensor is traceable measuring equipment (as required by ISO 9001). Conformity assessment: HBM will identify whether a torque sensor is outside the data sheet specifications.

Best price-to-performance ratio with guaranteed traceability Calibration in accordance with VDI/VDE 2646 requires two series of measurement in one mounting position (as opposed to DIN 51309). The following sensor characteristics are obtained from this calibration and specified in the calibration certificate:

Exact output signal for each calibration step
Optimized sensitivity (obtained from the increasing and decreasing series’ measured values, based on the least squares method)
Maximum linearity deviation
Maximum relative reversibility error
Remanence value
Furthermore, the calibration certificate specifies the measurement uncertainty. The required reproducibility data are based on statistical values resulting from similar calibrations. Besides HBM products, the database comprises many third-party sensors.

This calibration provides guaranteed proof that your torque sensor is traceable measuring equipment (in accordance with ISO 9001). Conformity assessment: HBM will identify whether a torque sensor is outside the data sheet specifications.

HBM also offers a working standard calibration with individually selectable load steps. The following sensor characteristics are obtained from this calibration and specified in the calibration certificate:

Exact output signal for each calibration step
Remanence value
Conformity assessment: HBM will identify whether a torque sensor is outside the data sheet specifications.

Our recommendation: We recommend calibration in accordance with VDI/VDE 2646 that, at the same price, provides you with more information about your torque sensor than the working standard calibration.

HBM offers the calibration of alternating torque in accordance with DAkkS-DKD-R 3-5. The following sensor characteristics are obtained from this calibration and specified in the calibration certificate:

Exact output signal for each calibration step
Reference straight line equation
Remanence value
Graphical representation of the deviation from the reference straight line
