C18 - Compact Force Transducer Measures Large Forces Precisely

Suitable applications for the C18 compressive force transducer include calibration tasks in areas where only confined mounting space is available. Due to its low weight it is also ideally fit for mobile test applications. Based on the ring torsion principle, the transducer has a small diameter and a low profile.

New: Also available with a nominal (rated) force of 5 MN

The transducer is available in 11 models with different nominal (rated) forces ranging between 10 kN and 5 MN, allowing it to be used in a wide range of applications. The complete measuring body and the force applications parts (base and thrust piece) included in delivery are made from stainless steel. They ensure optimum test results and at the same time prevent error loads.

The force transducer is distinguished by its precision. Class 0.5 according to ISO 376 is guaranteed. Class 00 is even possible on request for nominal (rated) forces from 500 kN. Main applications include calibration tasks such as e.g. the classification of material testing machines, or ensuring traceability of industrial test equipment. For these purposes, HBM calibrates its force transducers in its own laboratory, which has been accredited as a DKD laboratory for the the past 25 years.
