Interface 3A Series Multi Axis Load Cells Instruction Manual

INSTALLATION INFORMATION

1. Interface model 3A Series multi-axis load cells must be mounted on a surface that is flat and rigid enough so as to not deform appreciably under load.
2. Fasteners should be Grade 8.8 for 3A60 thru 3A160 and Grade 10.9 for 3A300 and 3A400
3. Sensors should be mounted using the recommended screws and mounting torques in the table below.
4. Dowel pins should be used at all mounting surfaces.
5. For 3A300 and 3A400 at least two dowel pins should be used on the live end. Up to 5 can be used.
6. For sensors 500N and above, a thin coating of Loctite 638 or similar is recommended on the three mounting surfaces to prevent slippage.
7. Mounting fixtures and plates may only contact the sensor at the indicated mounting surfaces.
