Shaft Style Rotary Transformer Method

TMNR-ME Series

Features
  • Measures torque from geostationary axis to high-speed spindle by double bearing adoption
  • Possible to use for testing and instrument control, not just torque measurement
  • Horsepower measurement for motors can be performed by installing a rotation detector
