easily installed as part of the conveyor drive either when first installed or as a retrofit application referring now to fig3 a 3c an exemplary installation sequence is depicted in fig3 a the compression screw 19 is shown butted against a face 35 of the floating frame 15 in order to install the force sensor 31 a jack 51 or other similar device is positioned between the fixed frame 27 and the face 35 a jack member 53 is extended to move the floating frame 15 in the direction x as shown in fig3 b to create a space 41 to receive the force sensor 31 the force sensor 31 is inserted in the space 41 and the jack pressure is released to allow the floating frame 15 to travel in the direction y as shown in fig3 c as part of the process the compression screw 19 can be backed off as well to facilitate inserting the force sensor 31 in the space 41 the force sensor 31 is now installed and can be utilized to monitor chain pull force as described above the moving of the floating frame 15 as depicted in fig3 a can be done while the conveyor drive is still running once the jack 51 is removed the conveyor chain is.
