Measurements are becoming ever more accurate, instruments increasingly precise. Metrology as a branch of science focuses on measurement - reproducibility of measurement results throughout the world is key in this context. Hence it is essential in metrology to guarantee traceability from any calibration level to the primary standard. The primary standard is ensured by the national metrology institute and is the standard with the smallest measurement uncertainty in the respective country.
Metrological traceability needs to be guaranteed
These traceability "chains" for ensuring the reproducibility of measurements in practice are based on reference measurement chains implemented with HBM transducers and highest-precision measuring instruments. Over 100 metrology institutes throughout the world use HBM highest-precision test and measurement equipment.
Users benefit from the fact that strain gauge technology enables measurement chains with an extremely small measurement uncertainty to be implemented which, at the same time, have excellent long-term stability.
