Accelerometers should be mounted onto a surface that is free from oil and grease as close as possible to the source of vibration. The surface should be smooth, unpainted, flat and larger than the base of the accelerometer itself.

How do you attach accelerometers?

Use an insulated cap screw to securely mount a ring-style accelerometer. Insert the cap screw into a through-hole in the accelerometer housing and screw it into a tapped hole on the mounting surface (see Figure 3A). The tapped hole should be deep enough so that the screw does not bottom out in the mounting structure.

Where is the accelerometer located on the aircraft?

Strap-Down INS. Ring Laser Gyros and accelerometers are attached rigidly, or “strapped down”, to the frame of the aircraft i.e. as the aircraft moves, so does the INS platform - exactly. Three gyroscopes sense the rate of roll, pitch, and yaw; and three accelerometers detect accelerations along each aircraft axis.
