RVDT/RVIT Position Sensors

RVDT (Rotary Variable Differential Transformer) and RVIT (Rotary Variable Inductive Transducer) sensors feature precision ball bearings and non-contact inductive magnetic coupling for extremely long cycle life and virtually infinite resolution. Various off-the-shelf and custom packaging options are available for the most demanding application requirements. Our AC operated RVDTs are compatible with our full line of signal conditioners, panel displays and mini-controllers.

Product Features

  • AC operated RVDTs measure rotary position up to ±60 degrees
  • DC RVDTs and RVITs measure up to ±75 degrees with DC voltage output
  • Custom measurement ranges are available
