Abstract: To reduce the construction effort and also to make it smaller, the detector coil (6) is formed in the detector head (7) of a magnetostrictive position sensor (100) in a semiconductor chip (2), in which at the same time also the evaluation circuit (16) is formed and—if biased electrically and by means of direct current—also the then necessary separate bias coil (18).

Abstract: Since the functional unit (PS-F) of a position sensor is no longer to be repaired in the event of failure, but is to be replaced completely—which is nevertheless to be canred out according to the principle of bloodless removal, especially when arranged in a piston of a working cylinder unit—according to the invention, such functional units are manufactured in different dimensions and possibly also functioning according to different measuring principles in a very simple and cost-effective manner and according to the modular principle in that a functional rod (FS) of the functional unit (PS-F) on the one hand the electronics board (2) with the evaluation unit (12) on the other hand are each inserted opposite the pot-shaped head housing (1), from which the functional rod (FS) then protrudes from the open side (1a), and are pre-fixed to the latter, and the head housing (1) is then cast from the open side, which only brings about the firm connection between the evaluation electronics (12) on the one hand and the f

Abstract: In order to prevent gap corrosion at a freely accessible face of a threaded connection (1) in particular when used in sea water the threaded connection (1) is encapsulated in a circumferential tight annular chamber (3) in order to prevent a penetration of sea water to the threaded connection (1) and thus prevent the gap corrosion between the two threads (2, b) of the threaded connection (1) meshing with each other. This is achieved by a particularly pressure tight and long service life primary seal (6) and advantageously a supplemental secondary seal (16), in particular for a threaded connection (1) which seals a cable pass through (15) of a housing (22).

Abstract: In order to arrange a sensor unit completely in an interior e.g. of a cylinder of a piston cylinder unit and in order to be able to use a tension element sensor as a sensor the sensor unit is configured so that it includes a pressure tight wall through which a magnetic field sensitive sensor is configured to detect a magnetic field of an encoder magnet that moves on another side of the pressure tight wall and represents a rotational position and rotations of the winding drum whereas a housing of the sensor unit is sealed relative to an interior of the cylinder so that the sensor cavity in which the sensor is arranged represents a low pressure cavity which is advantageously only subjected to ambient pressure. This avoids hollow boring of the piston rod and no magnetic field permeable window has to be fabricated in a wall or in a base of the cylinder.

Abstract: In order to minimize a force transfer at electronic components (1), in particular sensors (1) whose electronic circuit in an interior of a housing (2) is encased by an initially liquid or highly viscous hardening encasement compound (20) at an increasing temperature from the hardened encasement compound to the electronic components (4, 24) it is proposed according to the invention to perform the encasement so that in the cured condition all required portions and components (4, 24) are covered by the encasement compound (20) but sufficient cavities (21.1, 22.2) remain in the interior spaces (14.1, 14.2) of the housing (2) so that the hardened encasement compound (20) can expand into the cavities.

Abstract: In order to configure a housing (3) for a sensor received in the housing as deformation stable as possible the housing is made integrally in one piece from metal instead of being made from plastic and furthermore the pass through openings (6a, b) for attaching the sensor by bolting to another component are sized and positioned so that impartible forces are not able to deform the housing (3) which has a defined stability.

Abstract: Instead of tapping a mechano-elastic desnity wave (MEDW) from a wave conductor or a Villary band through a detector coil, a changing field strength H is captured by a XMR sensor which is positioned on a wave conductor or proximal to the wave conductor or on a Villary band or proximal to the Villary band.

Abstract: In order to configure a housing of a sensor, in particular of an angle sensor, long term leak tight in the best way possible a cover is not glued into the pot shaped housing or screwed in and sealed, but welded in the housing through a laser. In spite of the sensor chip already being in the housing, the heat induction is so small that the sensor chip is not damaged even though the sensor chip is very small.

Abstract: In lateral outriggers, e.g. of a mobile crane touch-free position sensors are arranged for the extension length and the operating range of the mobile crane is limited as a function of the currently measured values. In particular the touch-free magnetostrictive position sensors in a very flat housing can be well arranged between the particular telescope profiles without being exposed to the risk of damages.

Abstract: The tension element position sensor includes three housing elements, wherein the two outer housing elements are configured pot shaped with a base towards a center housing component, wherein one element is the spring motor and the other is the rotation angle sensor. Thus the rotation angle sensor includes two Hall sensors, wherein an encoder magnet rotates as a function of the rotation of the winding drum opposite to the faces of the Hall sensors on the face side of one respective gear of two gears meshing with one another. Herein the arrangement of the gears and circuit boards in the receiver of this lateral housing component is of particular importance. Also the spring motor can be completely preassembled and stored in a closed manner.

Abstract: To provide a thin and slender magnetic angle sensor, a main circuit board is disposed in the direction of the longitudinal axis of the sensor. This sensor element in form of a chip is supported on a sensor circuit board, which is positioned transversely to the main circuit board at the forward narrow side of the main circuit board.

Abstract: The rotational position of an encoder magnet can be scanned over more than 360° by respective sensor elements in that magnets are disposed on different stages of a suitable transmission, in particular of a differential transmission, and the magnets are scanned by separate sensor elements, whose signals are computed with one another and yield a total number of revolutions. In particular, when an assembly of this type shall be built very small, undesirable magnetic interferences for the sensor elements have to be avoided through flux conductor elements since the interferences distort the measurement results. Thus, a differentiation is made between active and passive flux conductor elements.

Abstract: In order to be able to compensate different temperature expansion of a magnetic tape, (measuring tape) and a support ring in an angle sensor where the magnetic tape is applied to a circumference of a component and where a scanning head is used, the magnetic tape is fixated at the support ring at the most at one location of the circumference and otherwise supported at the circumference with a tension band, so that the measuring tape can perform a movement relative to the support ring, and/or the tension band due to the expansion in circumferential direction.

Abstract: A method for using a band sensor for defining a position of a component in an interior of the housing. At least one magnet is coupled with a winding drum of the band sensor so the magnet is drivable in rotation about a magnetic rotation axis wherein a pole axis is disposed transverse to the magnetic rotation axis. The measuring band length varies with percentage of wind-up which is numerically compensated by processing electronics.

Abstract: For so-called pole wheels, as they are used for angle detection through magnetic field sensors, centering is facilitated and the service life of the pole wheel is increased by fixating the magnet ring rotationally and disengageable through sliding it on a prefabricated hub through a mounting device, which is disposed there between, like e.g. a friction locking band.

Abstract: In order to be able to deflect a free end of a measuring band of a measuring band sensor not only in a direction transversal to an inlet plane according to the invention the free end of the measuring band 3 arranged outside of the housing is twisted about its longitudinal axis by 90° at the most. This facilitates deflections of a total of 180°. When a deflection within the remaining 180° shall be facilitated, a torsion of the free end of the measuring band also has to be provided by 90°, but in the other direction with respect to the inlet plane.
