用于扫描器头的间隙和位移磁性传感器系统
Abstract:
一种用于造纸机或其它系统中的扫描器头的间隙和位移磁性传感器系统包括多传感器组件（414b）。多传感器组件包括多个磁场取向传感器（514x‑514z），所述多个磁场取向传感器被配置成捕获磁场（550 552）的测量结果以便标识（i）第一扫描传感器头和第二扫描传感器头在第一方向（X方向）上的位移以及（ii）第一扫描传感器头（410a）和第二扫描传感器头（410b）在第二方向（Z方向）上的间隙间隔，以及（iii）第一扫描传感器头和第二扫描传感器头在第三方向（Y方向）上的位移。磁场取向传感器中的至少一个（514z）被布置成从磁场的中心线（552）偏移，使得来自至少一个磁场取向传感器的输出指示间隙间隔和第一方向或第三方向上的位移的组合。
Abstract(English):

A gap and displacement magnetic sensor system for scanner heads in paper machines or other systems includes a multiple-sensor assembly. The multiple-sensor assembly includes multiple magnetic field orientation sensors configured to capture measurements of a magnetic field in order to identify (i) a displacement of first and second scanning sensor heads in a first direction, and (ii) a gap separation of the first and second scanning sensor heads in a second direction, and (iii) a displacement of the first and second scanning sensor heads in a third direction. At least one of the magnetic field orientation sensors is disposed offset from a centerline of the magnetic field such that an output from the at least one magnetic field orientation sensor indicates a combination of the gap separation and the displacement in either the first direction or the third direction.
