Abstract: A device for determining an external magnetic influence has a component comprising ferromagnetic material and a magnetizable region comprising at least three opposing magnetic tracks. The at least three magnetic opposing magnetic tracks are magnetizable in opposite directions, form at least two groups, and are arranged axially relative to the component. A first magnetic field sensor for emitting a signal is arranged radially to the component and assigned to the first group. A second magnetic field sensor for emitting a signal is arranged radially to the component and assigned to the second group. Redundant magnetic field sensors, each configured for emitting a signal, may be arranged radially in relation to the component for each of the first and second groups. The signals of the first and the second sensors can be set in relation to each other and in relation to the signals of the redundant first and second sensors.

Abstract: A sensor assembly includes an annular target body disposed about a rotatable member outer surface and an annular angular position indicator with at least one angular position index corresponding to an angular position of the member. Radial displacement sensors are spaced circumferentially about the axis and radially outwardly from the target body outer surface. A reference sensor is disposed circumferentially between two of the radial displacement sensors, has an inner end spaced outwardly from the target body surface by a first spacing distance, and is configured to detect the target body. An angular displacement sensor is spaced axially from the reference sensor and has an inner end spaced outwardly from the position indicator surface by a second spacing distance. The angular sensor is located such that the second spacing distance is generally equal to the first spacing distance and such that the position index passes the sensor inner end.

Abstract: An apparatus for detecting a magnetically conductive object in a detection area has an electrical coil and at least one sensor element. The apparatus is intended to be as free of degradation processes as possible and thus requires little maintenance and is configured and set up with the highest possible degree of redundancy and measurement reliability. For this purpose, the coil is set up to form a magnetic field in the detection area and the sensor element is configured to detect a magnetic field with a field strength, the magnitude of which is greater than a predefined threshold value. The threshold value is set to be higher than the field strength present in the detection area when the magnetically conductive object is absent and lower than the field strength present therein when the object is present.

Abstract: A rotation angle detecting device includes a resolver that outputs three-phase signals based on a rotation angle of a rotary shaft, and an R/D converter that acquires the three-phase output signals via signal lines corresponding to the respective phases. The R/D converter determines the rotation angle of the rotary shaft on the basis of the three-phase output signals. The R/D converter includes switching elements that change the potential of the first-phase signal line and the potential of the second-phase signal line, respectively.

Abstract: Sensor assemblies and methods of assembling and using the sensor assemblies are provided for monitoring operational characteristics of subsea rotating devices such as subsea motors and pumps. Pressure-compensated proximity sensor tip assemblies configured to withstand subsea pressures are mounted adjacent a subsea rotating shaft for directly monitoring a position of the rotating shaft during dynamic operation thereof. An end of a sensor housing opposite a sensor tip assembly is mounted to a wall of the device housing. The sensor housing defines a fluid reservoir containing a substantially incompressible fluid therein that is in fluid communication with the interior portions of the proximity sensor tip assembly. A length of the sensor housing is adjusted to accommodate a distance between the wall of the device housing and the rotating shaft.
