As shown in Fig. 2 the how channel modularized thickness detection apparatus of present invention high accuracy, mainly include：Thickness measuring lower roll
1st, floating bearing component 2, magnetic steel frame component 3, circuit board assemblies 4, shell fragment fix shaft assembly 5, Limit Bearing
6th, shell fragment 7 etc., concrete structure is as follows：
Bearing in floating bearing component 2 and the relative and noncontact about 1 of thickness measuring lower roll, floating bearing component
2 upper one end arranges shell fragment 7, and floating bearing component 2 is installed on shell fragment by shell fragment 7 and fixes shaft assembly 5
On；The top other end of floating bearing component 2 arranges magnetic steel frame component 3, magnetic steel frame component 3 and circuit board group
Linear transducer in part 4 is (such as：Magnetic tunnel-junction linear transducer) it is corresponding, form modular construction.Institute
Setting Limit Bearing 7 below the top other end of floating bearing component 2 is stated, Limit Bearing 7 is free state,
The bearing and thickness measuring lower roll that prevent in floating bearing component 2 are moved down for limiting the bearing in floating bearing component 2
1 contact, it is to avoid abrasion occurs between the bearing and thickness measuring lower roll 1 in floating bearing component 2.Shell fragment 7 with
Under the cooperation of Limit Bearing 6, it is ensured that the gap between bearing and thickness measuring lower roll 1 in floating bearing component 2 is not
Become.
