A sensor assembly that includes a sealed housing. A printed circuit board assembly including a first section that includes processing circuitry is disposed within the sealed housing and a second section that includes detection circuitry extends from the sealed housing. The sensor assembly also includes a conductive target movably coupled to the second section of the printed circuit board to vary net voltage of the detection circuitry as the conductive target moves along the second section to provide an output signal. The processing circuitry detects the output signal and converts the output signal into a linear representation of position of the conductive target in relation to the second section.

Inductive sensor assembly for fluid measurements

A method for detecting a relative position of a magnetic field source is disclosed. The method comprises the steps of detecting at least two magnetic field components of a magnetic field produced by a magnetic field source using a magnetic field sensor, determining a temperature effect compensation which compensates for a temperature effect on the magnetic field components, and establishing an output signal corresponding to the relative position of the magnetic field source based on a quotient of the magnetic field components, the temperature effect compensation, and an offset correction.

Temperature compensation method of magnetic control fields in a hall sensor with OS adaption

A displacement sensor is disclosed for contactlessly measuring a relative position of a magnetic field source which produces a magnetic field and a magnetic field sensor in relation to each other, wherein the magnetic field source and the magnetic field sensor are movable relative to each other. Each magnetic field probe detects at least two spatial components of a magnetic flux density of the magnetic field. A storage unit stores individual position signals. A control and calculation unit calculates an output signal of the displacement sensor based on the position signals, and calculates a magnitude of the magnetic flux density and compare it with a predetermined threshold value to output a current calculated position signal for each magnetic field probe if the magnitude is greater than the threshold value and to output a preceding stored position signal if the magnitude is less than or equal to the threshold value.

Displacement sensor for contactlessly measuring a relative position by means of a magnetic field sensor array on the basis of the hall effect

The present invention relates to a method for contactlessly measuring a relative position of a magnetic field source () which produces a magnetic field and a magnetic field sensor () in relation to each other. The present invention further also relates to a corresponding displacement sensor. The invention describes an operating principle of a sensor which is based on the Hall effect and which achieves an increase in the sensor output range with a magnet which is simultaneously reduced in size by storing the earlier value when control by the magnetic field is lost. In particular, the method comprises the steps of: calculating the position signal on the basis of a quotient of two magnetic flux density components; calculating a magnitude of the magnetic flux density and comparing the magnitude with a predetermined threshold value; outputting the current calculated position signal if the magnitude of the magnetic flux density is higher than the threshold value; outputting a preceding stored position signal if the magnitude of the magnetic flux density is smaller than or equal to the threshold value; storing the output position signal.

Method for contactlessly measuring a relative position by means of a 3D hall sensor having measurement signal store

The present invention relates to a method for contactless measurement of a relative position of a magnetic field source, which produces a magnetic field and a magnetic field sensor in relation to each other. The present invention further relates to a corresponding displacement sensor. According to the present invention, the magnetic field sensor detects at least two spatial components (Bz, By) of the magnetic field and a position signal is produced from the measured components. The method comprises the following steps of calculating the position signal based on a quotient of the two magnetic field components; and correcting, before the quotient is calculated, the magnetic field component, which extends in a movement direction between the magnetic field source and the magnetic field sensor.
