摘要： A measurement system (74) for determining an angular position of a component of a gas turbine engine (20) includes one or more proximity sensors (76; 76a, 76b) positioned at a fixed structure of the gas turbine engine (20) and one or more sensor targets (80, 82) positioned at a rotatable component of the gas turbine engine. Each sensor target of the one or more sensor targets includes a target surface (84) having a variable distance between the target surface and the proximity sensor with rotation of the rotatable component about a component axis of rotation. A measurement of distance between the proximity sensor (76; 76a, 76b) and the target surface as measured by the proximity sensor is indicative of an angular position of the rotatable component relative to the component axis of rotation.
