Displacement measurement system and method using magnetic encodings

摘要: A measurement system includes a rotating member configured to transfer mechanical energy point of use. The has at surface thereof one or more circumferentially oriented bands magnetizable material. Each band magnetic pattern comprised plurality transitions magnetically recorded in the material that band. magnetic-field sensor is disposed sufficiently near each sense as rotates. generates signals response sensed by sensor. Processing electronics communication with receive generated while rotates and dynamically compute from associated performance member.
