  • Mechatronics in Medicine: A Biomedical Engineering Approach > Sensing Technology
    Rotary Variable Differential Transformer The rotary variable differential transformer ( RVDT ) is an angular displacement sensor which operates in a similar manner to the LVDT , the only difference being that it has a rotary ferromagnetic core. Incremental Encoders Incremental encoders are position feedback devices.
  • Modern Engineering for Design of Liquid-Propellant Rocket Engines > Design of Rocket-Engine Control and Condition-Monitoring Systems
    For valve-position sensing, the rocket-en- gine control will employ the rotary variable differen- tial transformer ( RVDT ) for measuring angular mo- tion and the linear variable differential transformer ( LVDT ) for measuring linear travel. Optical en- coders and ratiometric techniques, such as the track- ing resolver-to-digital converter, offer better accuracy and should be specified in new valve designs.
