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.
Calibration machines with minimal measurement uncertainty (in non-state calibration laboratories).
Dead-load machines (sensors are loaded with weights in the Earth’s gravity field) up to 240 kN, extraordinary for a private calibration laboratory.
Machine accuracy up to 0.005% with compressive loading or 0.008% with tensile loading.
Competence up to 5 MN for tensile and compressive loading.
Optimize your measurement uncertainty assessment using the actual transducer characteristics - instead of data sheet specifications only.
Choice of different calibration standards:
Working standard calibration.
Measurement chain or sensor? ISO 376 to meet the highest demands or DAkkS-DKD-R 3-3? It's your choice. We will be happy to advise you.
The HBK calibration laboratory offers many advantages when it comes to calibrating your force transducer:
If you want to know everything about your sensor: The sensor is measured in three varying mounting positions. That means: The sensor is rotated by 120° in the machine in each case - i.e. the force transducer needs to be mounted and dismounted three times. The following characteristics are obtained from ISO 376 calibration and specified in the calibration certificate:
Moreover, the calibration certificate specifies measurement uncertainty as per ISO 376, i.e. for ascending as well as ascending and descending force series. HBK provides additional information such as measurement uncertainty including the effect of hysteresis as a special service at no additional cost. This goes beyond the requirements of the standard. This calibration provides guaranteed proof that your force sensor is traceable measuring equipment (as per ISO 9001).
Best price-to-performance ratio with guaranteed traceability Calibration per DAkkS-DKD-R 3-3 requires measurement in one mounting position only (as opposed to ISO 376). The following sensor characteristics are obtained from this calibration and specified in the calibration certificate:
Furthermore, the calibration certificate specifies the measurement uncertainty. The required repeatability and reproducibility data are based on statistical values resulting from calibrations of the same type. Besides HBK products, the database comprises many third-party sensors. This calibration provides guaranteed proof that your force sensor is traceable measuring equipment (as per ISO 9001). Conformity assessment: Should a force sensor be outside the specifications of the data sheet, HBK will point out this fact.
HBK offers working standard calibration with individually selectable load steps. The following sensor characteristics are obtained from this calibration and specified in the calibration certificate:
Our recommendation: We recommend calibration per DAkkS-DKD-R 3-3, which, at an identical cost, provides you with more information about your force sensor than the working standard calibration. We will be happy to advise you.

Professional force transducer calibration is a prerequisite for assuring the quality of your measurement results in the long term and is an integral part of your ISO9001 certification.
