<p>A refiner disk sensor (78) and sensor refiner disk (58) for use in sensing or measuring a parameter in a refining zone of a refiner (30). The sensor includes a spacer (114) that isolates a sensing element. In one embodiment, the spacer is made of a material that isolates the element from the disk to prevent disk heat from affecting sensor operation. The sensor preferably also includes a housing (140) carried by the spacer that, in turn, carries the element. Where the element is temperature sensing, the housing is thermally conductive and it an the spacer enclose the elemnt. Each sensor is disposed in the refining surface of a disk. In one embodiment, each sensor preferably is disposed in its own separate bore (96) in the disk flush with or below axial refiner bar height. In another embodiment, the sensor or sensors are part of a removable disk segment (32).</p> |
