Doctor for a paper machine |
| 摘要 |
A doctor for a paper machine that according to some implementations includes a blade, a wearing element located in or on the blade so that at least a portion of the wearing element is exposed to wear as the blade is worn, and a reading element positioned in proximity to the wearing element. The reading element is configured to emit a magnetic signal to excite the wearing element and the wearing element is configured to respond to the magnetic signal with a magnetic response signal. The reading element is in turn configured to receive the magnetic response signal, the magnetic response signal comprising a frequency that varies with the wear of the wearing element such that the frequency of the magnetic response signal is representative of the wear of the wearing element. |
