Bracket Guidelines
Avoiding the use of paint or any other sealant in and around the mounting holes of the bracket to ensure permanent electrical contact between probe shell, mounting bracket and machine.
The bracket must be stiff to avoid undesired vibration. Avoid thin bars.
The use of A36 steel, 10 to 3 mm thick [3/8” to 1/2”], is recommended. If need be, use lateral reinforcement to increase bracket stiffness.
Brackets should have a parallel plane with the shaft (to host the hole for the prox probe) so the probe sensing face is perpendicular to the shaft surface.
Brackets must be positioned close to the shaft to allow the probe gap to be in its target zone; Synchro probe must be 5mm to the shaft and 2mm to the metal target (glued on the shaft).
With point 5 in mind, avoid having a bracket with the probe fully extended to get in its target zone. It is optimal to keep the probe mostly centered in the brackets circular cut out.
Brackets can be bolted into place or welded so long as it meets the demands of points 1 and 2.
PCS/Synchro compound bracket must have a minimum elevation of at least 4 inches between the PCS proximity probe and Synchro probe.
