    • An industrial roll includes: a substantially cylindrical core having an outer surface; a polymeric cover circumferentially overlying the core outer surface; and a sensing system. The sensing system comprises: a plurality of sensors embedded in the cover, the sensors configured to detect an operating parameter of the roll and provide signals representative of the operating parameter, wherein one of the plurality of sensors is a tracking sensor and the remaining sensors are non-tracking sensors; and a processor operatively associated with the sensors that processes signals provided by the sensors. The sensors are arranged at a substantially equal radial distance from the core outer surface, such that they define a circle when viewed from an end of the roll. Each of the non-tracking sensors is further arranged at a substantially equal first angular distance from its immediate non-tracking sensor neighbors, two endmost non-tracking sensors defining an angular gap. The tracking sensor is disposed in the angular gap, such that a second angular distance defined by the tracking sensor and either of the endmost sensors differs from the first angular distance. In this configuration, the sensing system can identify from which sensor signals are generated without a trigger signal generator or accelerometer.
    • 工业辊包括:具有外表面的大致圆柱形的芯; 圆周地覆盖所述芯外表面的聚合物盖; 和感测系统。 感测系统包括:嵌入在盖中的多个传感器,传感器被配置为检测卷的操作参数并提供表示操作参数的信号,其中多个传感器中的一个是跟踪传感器,其余的传感器是 非跟踪传感器; 以及与处理由传感器提供的信号的传感器可操作地相关联的处理器。 这些传感器被布置成与芯部外表面基本上相等的径向距离,使得当从辊的端部观察时它们限定圆形。 每个非跟踪传感器进一步布置成与其直接的非跟踪传感器邻近部分基本相等的第一角距离,两个最终的非跟踪传感器限定角度间隙。 跟踪传感器设置在角间隙中,使得由跟踪传感器和任一最终传感器限定的第二角距离与第一角距离不同。 在该配置中,感测系统可以识别从哪个传感器信号产生而没有触发信号发生器或加速度计。
