Step 2) Mounting the accelerometer
1. Mount the accelerometer using a torque screwdriver for tightening. The supplied captive screw should be
torqued to a nominal value of 3,3895 Nm (30 lb-in). Under-torquing the accelerometer reduces the
stiffness of the coupling, while over-torquing can cause permanent thread damage.
Note:
Use Loctite 222 thread adhesive for better results.
Installation on an insulated bearing
1. Shown here is an alternate mounting
method. The sensor is installed on an
insulating block.
If the sensor is installed on an insulated bearing, special care must be taken to
preserve the insulation of the bearing.
The most widely recommended mounting method consists in placing a 0.063 in.
thick mica sheet between mounting bracket and bearing, and using non-metallic
screws.
