The requirement to prove traceability to national standards includes all equipment used for measurements and tests made for quality assurance of a company's products
The new TB2 reference torque transducer from HBM has been designed to ensure traceability of measurements as part of the ISO 9000 certification.
Any company aiming to receive certification to ISO 9000, or having already been certified, has to prove traceability to national standards.
This requirement includes all equipment used for measurements and tests made for quality assurance of a company's products.
The measuring body of the TB2 has been designed with axially arranged U-sections to give increased accuracy, especially for the temperature effect on zero signal, the linearity deviation and the reproducibility.
The models feature a very small uncertainty of measurement.
The relative standard deviation of repeatability is <+/-0.01%, the temperature effect on the zero signal is <+/-0.02%/10K and the linearity deviation including hysteresis is <+/-0.03%.
This means that the transducers are specified with an accuracy of 0.03 and typically achieve the best accuracy of 0.05 as specified by DIN 51309 or EA-10/14 already for initial values below 2%.
The strain gauge measuring system enables all types of SG full bridge amplifiers to be used.
These amplifiers, especially the DMP 40 digital precision amplifier or the MGCplus system's ML38 precision amplifier module, are used to integrate the transducers into the complete measuring chain provided by HBM.
This means: "The complete one-stop solution, from transducer through signal conditioning and evaluation software".
In addition, amplifiers enable easy linking to the different interfaces and fieldbus systems.
There are six models in the TB2 reference torque transducers series. These have nominal (rated) torque values of 500Nm, 1kNm, 2kNm, 3kNm, 5kNm and 10kNm.
