Variable Reluctance Torque Sensing Enabling flight control feedback and
rotating shaft health measurement
• Two sets of 3 Variable Reluctance (VR) sensors measure ferrous
targets on a spinning shaft (gear teeth, coupling features, etc.)
• Timing between the two sets of sensors used to determine shaft motion
in 5 degrees of freedom
• Able to accurately determine shaft twist to <0.001°, twist measurement
and shaft stiffness calibration used to calculate torque
• In production as flight control component on fixed-wing aircraft (DAL-A)
Wireless Torque Sensing
Enabling real-time health
measurement for rotating shafts

Torque-Link
• Scalable collar and small
electronics design enable
retrofit across broad range of
applications (<1” to >10” shaft)
• Non-contact, eliminates slip
rings for both power and
measurement
• Lossless (LXRS) wireless
communication technology
• Battery or inductive coupling
