Series KTN-Z/D

Best-in-Class Force Transfer Standard Series KTN-Z/D
– ISO376 for Compression and Tensile Forces

Krafttransfernormal Serie KTN-Z/D – ISO376 für Zug- und Druckkräfte, für Kalibrierlaboratorien oder nationale Metrologische Institute von 5N bis 1MN (NMI)

Reference Force Transducer Series KTN-Z/D – Maximum Precision for Calibration Labs or National Metrological Institutes from 5N to 1MN (NMI)

The force transfer standards of the KTN-Z/D series are designed for measuring compression and tensile forces with the highest precision according to ISO376 class 00 and can likewise be used as reference force transducers or master sensors in calibration machines. For very low forces of 5 N to 100 N, a robust force transducer with integrated overload protection and M5 threads is available for supplementary force introduction. The measuring cables consist of high-quality double shielded wires that are perfect for this high-precision application. The KTN-Z/D series also boasts a broad spectrum of standard-compliant mounting adapters, as well as standardized connection dimensions.

Typical users of the KTN-Z/D force transfer standards include international metrological institutes, companies that perform calibration of force transducers as a service, and companies that use a large number of force transducers that have to be calibrated regularly.
