Device for measuring a physical value related to the rotation of a body

Abstract: Device comprises a fixed detection assembly (50) capable of detecting an opening (40), which acts as a marker within a rotating body that includes a metallic disk (36). The detector consists of a magnetic proximity sensor (52) and means (72) for testing the correct operation of the sensor. The latter is arranged externally to the proximity sensor and has no direct electrical contact with it. The sensor (52) is typically an inductor or similar. Typically the tester for correct operation of the proximity sensor is a coil surrounding the end of the sensor (52) and connected to a means for changing its state for example by short circuiting it.

System for measuring performance indexes of inductive sensor

Abstract: Provided is a system for measuring performance indexes of an inductive sensor. The system comprises a measuring platform, a sensor assembly, a sensor position adjusting device and a micro-motion system, wherein the sensor assembly comprises at least one sensor, a sensor measuring arm and a sensor measuring head arranged on the sensor measuring arm; the sensor position adjusting device is used for adjusting the sensor measuring head or adjusting the position of a measuring head of an inner diameter measuring arm assembly so that the sensor measuring head is kept to make contact with the measuring head of the inner diameter measuring arm assembly till the output value of the sensor is zero, and then the sensor measuring head and the measuring head of the inner diameter measuring arm assembly are locked; the micro-motion system at least comprises a micro-motion system actuator. The micro-motion system actuator at least comprises the inner diameter measuring arm assembly, an object bearing platform, a guide rail and a grating ruler, wherein the inner diameter measuring arm assembly is fixed to the object bearing platform, when the object bearing platform moves, the inner diameter measuring arm assembly can move together with the object bearing platform so that the sensor measuring head can move along with the inner diameter measuring arm assembly, and the displacement direction and the displacement of the object bearing platform are measured through the grating ruler.

Composite material marking wave

Abstract: A position sensor for a bearing arrangement is provided. The position sensor includes at least one shaft or bearing ring, an inductive sensor, and a composite marking ring connected to the at least one shaft or bearing ring. The composite marking ring is spaced apart from and aligned with the inductive sensor and includes a ferrous material ring having a wavy surface with a plurality of projections with valleys therebetween facing the inductive sensor. The inductive sensor detects a rotational angle position of the at least one shaft or bearing ring based on a proximity of the wavy surface to the inductive sensor. An outer layer formed of a filler material is arranged at least on the wavy surface of the ferrous material ring. The filler material comprises a non-ferrous material and the outer layer provides a constant predetermined spacing between the composite marking ring and the inductive sensor.

Sensor device, in particular for a projectile

Abstract: The sensor arrangement (12) for sensing an approximation on an object and/or for sensing a fly-by on the object from ferromagnetic material, comprises two sensor coils axially extending with one another and turned together in row. The winding sense (14, 16) of the sensor coils (S1, S2) is opposite to the winding sense of another sensor coils. The sensor coils possess same coil parameters and same number of turns.

Electronic lock for power line

Abstract: An electronic lock for a power line. The electronic lock comprises a controller and a sensor, wherein the sensor is electrically connected to the controller via a shielded wire. The controller comprises an inner shell and an outer shell, wherein both sides of the inner shell are provided with fasteners, the fasteners are provided with fluorescent spots, and the outer shell is correspondingly provided with fastener holes; the inner shell is provided with a plug-pull wiring female header, and the outer shell is correspondingly provided with an adapted plug-pull wiring pin header and is provided with an external wiring terminal corresponding to the plug-pull wiring pin header in a manner of electric connection.
