摘要： A system for measuring a conveyor belt includes a first detector fixed at a location along a path of a conveyor belt. A first signal generator is affixed at a first location of the conveyor belt such that the first signal generator is detectable by the first detector when the first signal generator is in range of the first detector. The first detector is configured to provide a first signal as the first signal generator approaches the first detector. The first detector is configured to provide a second signal as the first signal generator moves away from the first detector. A processor is in electronic communication with the first detector and configured to calculate a belt speed based on an elapsed time between the first signal and the second signal.

摘要： The invention relates to a method and apparatus for measuring lay length of a wire rope having a number or external strands to form a rope having spiral grooves in the surface between the strands. A magnetic flux circuit is generated, part of which is formed within a region of the advancing wire rope. Variations of magnetic field around the region of the rope or variations of magnetic flux entering or leaving the rope are sensed by at least two sensors arranged around the rope. Signals from the sensors are subtractively combined to eliminate variations due to off-axis movements of the rope, and the combined signals reveal an oscillating pattern due to the undulating surface of the rope. Linking the oscillating pattern to distance along the rope reveals the lay length, which corresponds to a number of oscillations which is the same as the number of strands at the surface.

摘要： A length measuring system includes a magnetic component having two helical magnetically conductive or magnetic elements which have first and second axial ends. The elements are arranged in an axially symmetrically manner relative each other along a common longitudinal axis such that a magnetic field can be formed between the elements, the angle of the field relative to the common longitudinal axis continuously rotating along a predetermined length. The length measuring system further includes a magnetic sensor which can be arranged between the two elements at a right angle to the common longitudinal axis of the elements and which is connected to an evaluation unit.

摘要： A linear sensor uses four spaced apart magnets arranged in a rectangular array and has an axis of symmetry. Each magnet has a staircase shape of at least two steps ascending towards a centerline. Each magnet of the array has a single N-S with magnets arranged as mirror images about the axis of symmetry having opposed poles, and magnets located on diagonals defined by the rectangular array having the same pole facing the axis of symmetry. The linear sensor employs a magnetic field sensor such as a programmable Hall effect sensor that is mounted for movement relative to the magnetic array along the axis of symmetry. The height of the steps defining the staircase shape of the magnets is selected to produce a magnetic field of selected linearity along a selected portion of the axis of symmetry.

摘要： A non-contact system suitable for measuring velocity/distance of an object travelling inside a ferromagnetic pipeline utilizes magnetic dipoles written into the pipe surface by a transmission coil. These dipoles can be detected by a magnetic detector situated a fixed distance from the transmission point. If the time taken for a dipole to travel from the transmitter to the detector is recorded then this time will be proportional to the velocity of the system. The system functions both as a velocity measurement device and as a distance marker.Once the system detects a dipole it requests a further imprint, hence, a constant spacing is maintained between dipoles equal to the spacing between transmitter and detector.
摘要翻译：适用于测量在铁磁管道内行进的物体的速度/距离的非接触式系统利用通过传输线圈写入管表面的磁偶极子。这些偶极子可以通过位于与传输点固定距离的磁性探测器来检测。如果偶极子从发射器行进到检测器所花费的时间被记录下来，那么这个时间将与系统的速度成比例。该系统既作为速度测量装置又作为距离标记。一旦系统检测到偶极子，就要求进一步的印记，因此，在等于发射器和检测器之间的间距的偶极子之间保持恒定间隔。
