C18 Force Sensor: Dependable, Cost-Effective, and Precise C18 Force Sensor: Dependable, Cost-Effective, and Precise | HBM

C18 Reference Force Transducer: Transfer Devices for Large Compressive Forces

The C18 reference force transducer measures compressive force based on the ring torsion principle and is, therefore, particularly insensitive to temperature gradients, lateral force and bending moment. As far as capacity is concerned, the transducer is small and light-weight, and therefore, easy to transport and install in different locations. Its hermetically sealed stainless steel design, with an IP68 degree of protection, ensures a robust performance and long-term stability. 

The C18 series covers capacities ranging from 10 kN to as high as 5 MN. Besides, it meets the requirements of a transfer device for traceability of a force measurement machine to a standard. The transducer is also well-suited for use as a working sensor in calibration machines or as a working standard in companies that need to ensure dependable traceability of measuring equipment. The C18 is used in many national metrology institutes and is also well-suited to mobile applications as well as in the extremely precise determination of the center of gravity, for example, of an aircraft.

A C18 transducer is always calibrated, and comes complete with a mounting base and thrust piece. No additional load application parts are required. Overall, the C18 provides users with an extremely cost-effective solution.
