Description
The model F2221 tension/compression force transducer in miniature design with strain gauges is suitable for both static and dynamic force measurement in the direct force flow.
The force introduction is carried out via threaded bolts at both ends of the instrument. The force is thus transmitted centrally and evenly into the instrument. This enables precise measurement of the actual tension or compression forces in a wide variety of applications, for example to determine the actual tension forces in wire ropes or rod systems.
Special features
- Rated forces from 0 ... 2.25 lb to 0 ... 11,240 lb [0 ... 10 N to 0 ... 50 kN]
- For static and dynamic measurement
- Force introduction via threaded bolts
- Tension/Compression calibration
- Compact miniature design, confined mounting situations
