Model F1848 Compression force transducer
Compression force transducer
The force transducer model F1848 is used because of its redundant output signal very often for monitoring used by safety applications. The spherical calotte (spherical load application button) allows for a very simple force introduction.
Compression force transducers are used for the determination of compression forces in a wide variety of applications and are suitable for static and dynamic measuring requirements.
