  • Displacement sensor
    Patent number: 8729912
    Abstract: A linear capacitance displacement transducer (1) comprising first (2) and second (3) fixed capacitor plate and a dielectric structure (5) moveable longitudinally within a space (4) between the first (2) and second (3) capacitor plates, the dielectric structure (5) being operatively coupled to a moveable element (8). The capacitor plates and the dielectric material may be cylindrical and disposed coaxially and concentrically. The transducer (1) enables a displacement sensor that is capable of monitoring liquid levels in a syringe type drug reservoir (101) with sufficient sensitivity as to allow detection of erroneous drug delivery. The sensor is inexpensive to manufacture and provides reliable performance through robust design.
    Type: Grant
