    摘要： A position sensor system (200) for measuring a position (Z) of a target (220) movable outside a plane (230), the system (200) comprising: a first magnetic sensor (201) and a second magnetic sensor (202) fixedly arranged in said plane (230) and spaced apart by a distance (D); the first respectively second magnetic sensor (201, 202) adapted for measuring at least one first respectively second in-plane magnetic field component (Bu1, Bv1),(Bu2,Bv2) in said plane to obtain at least a first respectively second value; a controller (240) connected to the sensors for obtaining said values, and adapted for determining the out-of-plane position (Z) as a function of the values and of the predefined distance (D). A method (1200) of determining said position.

    摘要： Method of testing a sensor device that comprises a single angle calculator and at least two magnetic sensor elements, comprising the steps of: a) obtaining signals from the sensor elements; b) amplifying and digitizing the signals from the sensor elements; c) applying a first input value (IN1) derived from the digitized signal, to the angle calculator, to obtain a first angle value (α); d) applying a second input value (IN2) derived from the digitized signal, to the angle calculator, to obtain a second angle value (β); e) performing a consistency test of the first and second angle value (α, β); f) detecting an error of the sensor device or the angle calculator based on an outcome of the consistency test.

    摘要： Method of determining a gradient of a magnetic field, comprising the steps of: biasing a first/second magnetic sensor with a first/second biasing signal (11, 12); measuring and amplifying a first/second magnetic sensor signal (v1, v2); measuring a temperature (T) and/or a stress difference (ΔΣ); adjusting at least one of: the second biasing signal, the second amplifier gain, the amplified and digitized second sensor value (A_V2) using a predefined function f(T) or f(T, ΔΣ) or f(ΔΣ)of the measured temperature and/or the measured differential stress before determining a difference between the first/second signal/value derived from the first/second sensor signal. A magnetic sensor device configured for performing this method. A current sensor device. A position sensor device.
