Contactless position transducer
Measures fuel valve and inlet guide vane position with no mechanical wear. It comes in TCV and NGV types with an intrinsically safe (EEx ib) housing. One version sits inside the guide-vane hydraulic actuator: it works in 60 bar hydraulic oil at high temperature, is fast and accurate enough for position control, and brings its signal out through the actuator wall.
