Force Transfer Standards According to ISO376 Class 00 and Torque Transfer Standards According to DIN51309 Class 0.05 – and Better: GTM Accuracy Class VN
In addition to high-precision force, torque and multi-axis transducers GTM, as a worldwide leading supplier of best-in-class transducers, also offers compatible high-precision transfer standards for forces and moments. Especially noteworthy are the force transfer standards of the KTN-D series and the torque transfer standards of the Dm-TN series: Both transfer standard series exceed the highest metrological standards for force measurement (ISO376) and torque measurement (DIN 51309) many times over! Even if these high accuracy standards are not always required from an economical point of view, they impressively demonstrate GTM’s core competence as best-in-class provider for the precision measurement of forces and moments.
The team of experts at GTM strive to always give you uncompromising precision and quality at an excellent price-performance ratio. This philosophy is especially evident in GTM’s transfer standards, since GTM force transfer standards are used by National Metrological Institutes (NMI) and accredited calibration labs for inter-lab tests (round robin tests) at the same metrological instance. This makes them a central component for seamless national traceability with all uncertainties of measurement from the national standard to industrial measurement systems. Extremely high precision or lower uncertainty of measurement throughout all metrological stages, from industrial measuring systems to national standards, is a real advantage for every user of force and torque sensors, as well as multi-axis transducers.
GTM Transfer Standards offer Maximum Reliability
All GTM force transfer standards of the KTN series feature very high repeat accuracy of ≤50 ppm with different standard force measurement systems and ≤20 ppm under comparable test conditions. They achieve exceptional long-term stability and are hermetically enclosed. Eccentric strain, interference or bending moments have only a minimal effect on the accuracy.
GTM transfer standards are also time-proven as reference transducers or master sensors. In this application, the transfer standards are used directly in the testing or calibration systems. The premise of seamless traceability of measurement systems is of course also given here and can be fulfilled excellently with GTM transfer standards. Especially companies that offer calibration as a service, and high-volume manufacturers of strain gauge-based measuring sensors such as load cells, torque transducers or weighing cells benefit from the reliability and precision of GTM transfer standards.
The Entire Reference Measuring Chain from a Single Source
The high-precision measuring amplifiers of the CFA225 series are also a very important and indispensable component in metrological applications in order to implement a precise, reliable and traceable metrological measuring chain from a single source. The CFA225 series is based on a bridge supply voltage of 5 V and, as the name implies, a carrier frequency of 225 Hz. It offers the lowest uncertainty of measurement in traceability to national standards available today.
