Installation & Setup Guidance
Proper installation of the Bently Nevada 21000-16-10-15-085-03-02 is essential for accurate measurements. Follow these guidelines:
- Ensure the mounting thread (3/4-14 NPT) matches your machine's port. If the standoff adapter option is not 00, the default is 02.
- For probe penetration lengths between 1.0 and 2.0 inches, counter boring the machine case may be necessary to reduce side view or rear view effects.
- If the combined probe penetration (C plus D) exceeds 300 mm (12 in), add sleeve support near the probe to prevent resonance.
- Adjust the probe penetration within the 13 mm (±0.5 in) range to achieve optimal gap.
- Use the provided cable seal grip with appropriate grommets to secure cables and maintain the enclosure rating.
Maintenance & Reliability
To ensure long-term reliability, inspect the Bently Nevada 21000-16-10-15-085-03-02 periodically. Check the O-rings and thread seal for wear, and verify that all fittings remain tight. The aluminum body and stainless steel sleeve resist corrosion, but in harsh environments, regular cleaning is recommended. Because the unit is explosion-proof, avoid modifying the housing; any damage could compromise safety certifications.
Selection Guide & Purchasing Advice
When ordering a replacement or new housing assembly, verify that the model number 21000-16-10-15-085-03-02 matches your requirements, especially the probe length and mounting thread. Consider the cable length and penetration options to ensure compatibility with your machine configuration.
