Product Usage Instructions

Measuring Platform Mounting:
The measuring setup must be attached to the mounting surface of the measuring platform of the 3AR sensor using the specified cylinder head screws and cylindrical pins.

Steps:

1. Ensure the mounting surface meets the specified requirements.
2. Use the correct screw diameter and tightening torque as per the table.
3. Fasten the setup with 8x cylinder head screws and position with 2x cylindrical pins.

Stator Mounting:
The 3AR sensor must be attached to the screwing surface of the stator following the provided guidelines.

Steps:

1. Prepare the stator surface ensuring it meets the specified requirements.
2. Utilize the recommended screws, pin holes, and tightening torques as indicated in the manual.
3. Secure the sensor with 8x cylinder head screws and align using 2x cylindrical pins.

General Notes:

• Always refer to the provided table for strength class and tightening torque information.
• Ensure proper screw depth in both the measuring platform and stator.
• Follow ISO standards for tolerances and surface finish.

Frequently Asked Questions

1. Q: Can I use different screws for mounting the sensor?
   A: It is recommended to use the specified cylinder head screws for mounting to ensure proper installation and performance.

2. Q: What should I do if the mounting surface does not meet the specified requirements?
   A: It is crucial to have a rigid and flat mounting surface. If it does not meet the requirements, consult with a professional to rectify the surface before installation.

3. Q: Is it necessary to use all 8 screws for fastening?
   A: Yes, it is important to use all 8 cylinder head screws for secure attachment of the sensor to the mounting surfaces.
