Torque sensors for hollow shafts
Torque sensing inside the hollow shaft, with no external housing and no added length.
The measuring point moves inside the hollow shaft. Outside, the installation space stays as it was.
Torque measurement in hollow shafts: compact, dependable sensor technology
Melectric sensors measure torque directly in the rotating axis of a shaft, through a suitably placed bore, taking up almost no room and losing none of the precision. Excellent signal stability and IP69K protection suit them to industry, agricultural machinery and automotive and motorsport applications.
