  797L Piezoelectric Accelerometer and Cable_Installation - Rev. 1

ACCELEROMETER INSTALLATION

Supplies needed:

Mounting screw 1/4-28 UNF or M6x1

Loctite 222 thread adhesive

Tools needed:

Drill bits 7/32’’ or 5mm

Tap drills 1/4-28 UNF or M6x1

Torque screwdriver

Caution: Use great care in handling the Model 797L accelerometer. NEVER DROP it or hit it against a
solid object. Keep it stored in its box until you have surveyed and prepared the location suitable for
installation.

Step 1) Preparation of the mounting area 

1.  Select the best mounting location according to your application (refer to preliminary considerations).

Prepare the surface and mounting hole according to Figure 1 a) if the screw has UNF thread or Figure
1b) if the screw has a metric thread.
