FSG company produces angle displacement sensors in inductive, magneto resistive and optical types, which can be selected according to user needs. Inductive angle displacement sensors are non-contact, suitable for measuring points in severe vibration conditions. Magneto resistive sensors have good sealing properties and can measure control axis displacement and excavator knuckle arm angles. Optical angle displacement sensors are suitable for single or multi-turn coils, low temperature coefficients and digitally coded angle displacement output signals.
