Your torque sensor in our calibration laboratory
At ATESTEO, we have manufactured torque measuring technology for the automotive industry for over thirty years. In the field of drivetrain testing, we apply these measurement technology instruments ourselves. So that our demanding automotive customers, just like we ourselves, can rely on the extremely precise calibration during tests and measurements, there is the ATESTEO calibration laboratory.
Professional calibration of a torque sensor is decisive for the quality of its measurement result, especially for repetitive measuring routines. You will also need the calibrations of your torque sensors for ISO 9001 certification. In the ATESTEO calibration laboratory, both simple factory calibrations and higher-level DAkkS calibrations in accordance with DIN 51309 and VDI/VDE 2646:2019 are possible. Although DAkkS calibrations are more complex than factory calibrations, our many years of experience, our modern equipment, and our specially developed calibration facilities guarantee you fast project turnaround times.
The ATESTEO calibration laboratory is accredited by DAkkS and certified in accordance with

DAkkS calibrations of your torque sensors in accordance with DIN 51309 and VDI/VDE 2646:2019
If you wish to know everything about your torque sensor and have high demands on as well as high requirements for the sensor and measurement result, ATESTEO offers you DAkkS calibration of your torque sensor in accordance with DIN 51309 and VDI/VDE 2646:2019. Every calibration in the ATESTEO calibration laboratory is precise, fast, and traceable. During DAkkS calibration, your torque sensor is calibrated according to DIN 51309 or VDI/VDE 2646:2019 from 0.2 N·m to 20,000 N·m. For this purpose, it is rotated in three mounting positions, each by 120°. This gives you all the values you need for the functioning and certification of your torque sensor.
Scope of services of DAkkS calibration:
|Measurand/Calibration object||Measuring range/Measurement span||Measurement conditions/Procedure||Expanded measurement uncertainty||Remarks|
|Torque/Torque transducer||0.2 N·m to 20,000 N·m||DIN 51309:2005
|0.02%||According to the reference principle|
On a DAkkS calibration certificate, ATESTEO documents the traceability to national standards for the representation of units in accordance with the International System of Units. This makes your calibration internationally recognised as well.
Traceable results of DAkkS calibration in accordance with DIN 51309 on the calibration certificate – the measurement values on the calibration certificate:
- Exact measurement values for each step of calibration
- Reversal error (hysteresis)
- Repeatability and reproducibility
- Creep behaviour
- Return to zero point
- Remanence value
- Interpolation error (potential deviations of the measured value from the cubic and linear approximations)
- Values of the measurement uncertainty at every calibration step
- Classification in accordance with DIN 51309

Your calibration in our calibration laboratory
We start with your requirements and wishes. What does your torque sensor need to do? Which key values do you need? For which requirements and certificates do you wish to have a calibration? In a joint discussion, we clarify the initial situation and objectives. Then, a decision is made for a DAkkS calibration or a factory calibration of your torque sensor. After you have approved the quotation and placed an order, we calibrate your torque measurement equipment according to the specified criteria and return it to you as quickly as possible along with the calibration certificate.
1. Inquiry for calibration
Together with you, we determine the criteria for the DAkkS calibration or factory calibration of your torque sensor:
- Measurement range
- Calibration standard
- Direction of torque (clockwise, counterclockwise/anticlockwise)
- Manufacturer and/or type
2. Quotation for calibration
You receive a comprehensive quotation taking into account the defined criteria (including price and delivery date).
After you have ordered, you receive confirmation of your order from ATESTEO. Then you send your torque sensor to ATESTEO for DAkkS calibration or factory calibration.
4. DAkkS calibration
We perform DAkkS calibration or factory calibration of your torque sensor in our DAkkS-accredited calibration laboratory with short turnaround times.
FAQ – frequently asked questions about the calibration of torque sensors
The accreditation of the calibration laboratory provides you with additional security on the professional competence of the laboratory. The accreditation is assessed, confirmed, and monitored by the DAkkS (German Accreditation Body). As an accredited calibration laboratory, we are able to perform DAkkS calibrations of your torque sensors to the highest standard.
Unlike certification, which can be issued by different societies, accreditation is issued by a single authorized body and the number of people (e.g. press accreditation for a specific event) or companies is limited.
DAkkS is the national accreditation authority of the Federal Republic of Germany (the predecessor of DAkkS was DKD). It is a central building block of the quality infrastructure and issues accreditations in the field of conformity assessment. DAkkS acts in the legal mandate and in the interest of the state, the economy and the protection of society and the environment. (www.dakks.de)
The subject of the work of calibration laboratories is the determination of display errors of instruments and measuring systems as well as the values of measurement samples. The aim is to ensure accurate and reliable measurement results. The accreditation of testing and calibration laboratories is carried out according to DIN EN ISO/IEC 17025. (www.dakks.de)
Ein DAkkS akkreditiertes Kalibrierlabor ist somit befähigt, die physikalischen Größen auf das Nationale Normal zurückzuführen. Für jede Größe und jede Kalibriervorschrift wird eine spezifische Akkreditierung erteilt.
Ein DAkkS akkreditiertes Kalibrierlabor muss unabhängig und für jeden zugänglich sein.
According to ISO 9001 or DIN ISO 17025, measurement and test equipment must be regularly calibrated. The resulting calibration certificates issued by the calibration laboratory in accordance with DIN 51309 or VDI/VDE 2646:2019 are valid for 26 months. After this period, the equipment must be recalibrated if the risk of incorrect measurements is to be reduced and costs for recalls or rework are to be avoided.
Every sensor and the associated measuring chain are subject to a variety of influences that can affect the measuring accuracy, such as aging, wear, operating errors, overloading, external or internal damage. Therefore, depending on the measuring principle, accuracy requirements, and risk analysis, measuring instruments must be calibrated at regular intervals or after an event such as an accident or misuse. We will be pleased to advise you when a calibration is useful or necessary.
It all depends on the requirements. Only a DAkkS calibration guarantees the traceability of the results. Factory calibrations do not ensure traceability to national standards. In addition, quality management standards such as DIN ISO 17025 do not accept factory calibrations. So if you need to meet certain requirements, you need a DAkkS calibration from a DAkkS-accredited calibration laboratory. Only their calibration certificates ensure traceable measured values.
Calibration involves comparing the measured value of a torque sensor or torque transducer with a standard value. The measurement accuracy is defined through the documentation of the deviation. This requires precise and reproducible calibrations in a calibration laboratory with high competence where calibration equipment, automation technology, and software along with highly qualified and experienced torque specialists come from one source.
The main difference is that the DAkkS calibration according to ISO 17025 fully guarantees the traceability of the test specimen to the national standard. This means that the deviation from the standard is documented for each individual stage in the test chain.
We will be happy to advise you on the question of whether a factory calibration, which we will also be happy to perform for you, is sufficient for your application or whether a calibration according to DIN 51309 or VDI/VDE 2646:2019 makes sense.
For torque sensors and torque transducers, calibration intervals are defined based on the user’s requirements, taking into account the following factors
- Stability of the characteristic values of the test equipment based on past calibrations.
- Requirements of the measuring accuracy.
- Requirements of the quality measurement standards.
- Operating conditions such as temperature, humidity, soil (higher values or higher fluctuations have a strong influence on stability).
- Mechanical stress, high load changes, operating time, high speed (high and many load changes have a stronger influence).
Depending on the individual application and taking into account the factors mentioned above, shorter or longer intervals may be required. For a non-binding consultation on whether a factory or DAkkS calibration is suitable for you due to the conditions of use or the stress, our expert team of the calibration laboratory will be happy to assist you.
The DAkkS calibration of a torque sensor usually takes a few days. After the administrative details are clarified, the following steps are carried out:
Step 1: Acclimatisation in the calibration laboratory to reduce the influence of humidity and temperature. Duration: at least 10 hours (preferably overnight)
Step 2: Calibration, check measured values for plausibility, release after successful calibration. Duration: a few days
Step 3: Return shipment to our customer
On request, we will be happy to advise you on suitable transport companies.
We can also provide you with transport cases tailored to your measuring shaft at a reasonable price.
