Calibration service

As part of Danisense’s pursuit of precision and innovation, the Danisense Calibration Laboratory was constructed in 2017. The aim was to improve our technical proficiency and to grow our knowledge of current sensing technology. Since then, we have expanded and improved the calibration service to offer customers highly accurate and reliable calibration of current transducers, with some of the lowest uncertainties available. After learning and building our competence, the first ISO/IEC 17025 accreditation by DANAK was finalised in 2022. The primary objective of Danisense Calibration is always to give the customer useful and trustworthy results.

Calibration provides knowledge

Calibration is the comparison of measurement values delivered by a device under test with those of a calibration standard of known accuracy. This provides the device user with knowledge of how well the device performs in controlled conditions. Regular calibration of an instrument gives the user confidence in their test results and insight into the reliability of their system.

ISO/IEC 17025 ensures competence

ISO/IEC 17025 is the internationally recognized standard for calibration laboratories. While similar to ISO 9001, the standard demands high levels of competence in both management and technical aspects of the laboratory to ensure the impartiality and quality of the results.  

 The DANAK Accreditation document

Accreditation gives international acceptance

Accreditation is the independent conformity assessment by a third party against recognised standards. While each country has its own accreditation body, the EA and ILAC Mutual Recognition Arrangement (MRA) means that once accredited, the accreditation is accepted everywhere. This means that the customer can trust the high standard of the accredited laboratory anywhere in the world. 

Traceability links results to the SI units

Measurement traceability refer to an unbroken chain of comparisons relating an instruments’ measurements to a known standard. Primary standards are used to realise their unit of measure which directly corresponds to their definition in the SI unit system. From this, secondary standards can be calibrated and used in national metrological institutes (NMI) as national standards. By maintaining traceability in calibration, the chain links the users’ instrument directly to the defined physical units. This means that measurement results can be compared using the same units across the world if uncertainty is accounted for.

DC Calibration

We perform DANAK accredited ISO/IEC 17025 calibration of DCCTs at Danisense Calibration. Our measurement capabilities are found in DANAKs website: https://registry.danak.dk/registry/613/CAL613?lang=en 

The following table is an example of the uncertainties we provide at different current levels in DC calibration:

Calibration Frequency

  For current out we recommend every 3 years

   For voltage out we recommend every 1-2 years
