Interface 3A Series Multi Axis Load Cells Instruction Manual
INSTALLATION INFORMATION
- 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.
- Fasteners should be Grade 8.8 for 3A60 thru 3A160 and Grade 10.9 for 3A300 and 3A400
- Sensors should be mounted using the recommended screws and mounting torques in the table below.
- Dowel pins should be used at all mounting surfaces.
- For 3A300 and 3A400 at least two dowel pins should be used on the live end. Up to 5 can be used.
- For sensors 500N and above, a thin coating of Loctite 638 or similar is recommended on the three mounting surfaces to prevent slippage.
- Mounting fixtures and plates may only contact the sensor at the indicated mounting surfaces.
