Figure 2-1. Method A Installation
Method “B” If customer's tail pulley shaft has a 5/8" diameter stub shaft extending
from it and is concentric with the centerline of the driving shaft, use part
#002931 to couple 61-12 speed sensor to tail pulley shaft. (Refer to
Figure 2-2.) This coupling is not supplied with the speed sensor but may
be purchased separately from Thermo Fisher Scientific.
It would be advisable to provide two flat surfaces, 90 ° apart, on the stub
shaft for a good set screw holding power.
Align shaft flat spots with set screws on coupling. See Figure 2-2.
Tighten all set screws securely .
