Calibration and certification: force transducers
Calibration of standard reference force tension or compression load cells is usually performed by applying the protocol established by international standard ISO 376. Standard ASTM E 74 is also a protocol issued in the US. Other calibration protocols can be defined according to the use of the dynamometer and to the level of inaccuracy sought. These standards provide a classification of dynamometers according to accuracy criteria.
The obtained results are displayed in a value table or a mathematical polynomial allowing the user of the dynamometer to know the value of the force from the indication provided by the related electronic equipment. The determination of the related inaccuracy is also part of the calibration. This is established according to the guide "Guide to the Expression of Uncertainty in Measurement" established by the International Bureau of Weights and Measures (BIPM).

Force calibration software
Sensy has developed calibration software products.
Two of them have been designed upon request by specialized laboratories, for the rigorous management of a set of standard reference transducers and testing machines: SENSY ISO 376 software and SENSY ISO 7500-1 software. Other software can be developed upon request, leveraging all the expertise of our engineers and technicians.
Calibration and certification: torque meters
Torque transducer calibration has its particularities when compared to the calibration of a dynamometer : Torque applied is generally a pure torque when using an effective decoupling system. Therefore, calibration results are only usable for the measurement of a pure torque.
If the torque meter is used for dynamometer calibration or verification, calibration must either be :
Calibration laboratories addressed by SENSY often work in compliance with national standards such as DIN 21309 or procedures acknowledged as accredited by calibration laboratories according to ISO 17025 Standard.
The ISO 6789 international standard establishes a calibration procedure for dynamometric wrenches.
