Protection device of hot rolling channeling roll displacement sensor

The invention provides a protection device of a hot rolling channeling roll displacement sensor. The protection device comprises a magnetic rod protection cover and an electronic bin protection device. The magnetic rod protective cover sleeves the outer portion of the measuring magnetic rod of the displacement sensor, one end of the magnetic rod protective cover is fixed at the detecting magneticring of the displacement sensor, and the other end of the magnetic rod protective cover is fixed at the electronic bin tail cover of the displacement sensor; and the electronic bin protection device sleeves the outer side of the electronic bin body. According to the protection device, the technical problems that a hot rolling channeling roll displacement sensor is short in service life, detectiondata are distorted, and a detection magnetic ring and sensor magnetic induction are prone to abrasion are finally solved. 本发明提供了一种热轧窜辊位移传感器的保护装置，包括磁杆防护罩和电子仓保护装置；所述磁杆防护罩套装在位移传感器的测量磁杆外，一端固定在位移传感器的检测磁环外圈，另一端固定在位移传感器的电子仓尾盖；所述电子仓保护
