GTM - Model K Series -Precise, Robust and Configurable Force Transducers from 200 N to 630 kN
The K series force transducers use the jump ring principle as the only integrative measuring method in force measurement. These force sensors set standards for accuracy, reliability and quality. This particularly affects the very low sensitivity to parasitic influences (lateral forces, bending moments, torsional moments, temperature fluctuations). They can withstand forces up to 300% of the nominal force without breaking and up to 150% of the nominal force without zero shift. With a fixed cable connection, the K series force transducers achieve IP protection class IP68.
The K series is a force sensor that enables high-precision measurements across the entire measuring range - from the smallest load to the nominal force. This means that the same force transducer can be used for the largest possible measuring range and offers a reliable and economical solution for your force measurement - ideal for materials and component testing, for static and dynamic testing machines or demanding production applications for process control and quality assurance.
