Frequently Asked Questions

Question:
What specific probe model matches the 21000-28-10-30-065-04-02 assembly?

Answer:
This assembly integrates with the Bently Nevada 3300 XL 8 mm proximity probe series.

Question:
Can technicians install this housing in North American hazardous locations?

Answer:
Yes, CSA certification covers Class I, II, and III hazardous divisions across North America.

Question:
What advantages does the aluminum and stainless steel material combination provide?

Answer:
The aluminum body reduces total assembly weight while the 304 stainless steel sleeve resists corrosive industrial environments.

Question:
How do engineers select the correct standoff adapter length?

Answer:
Engineers calculate the required clearance from the machine case penetration to the probe tip, selecting the 3-inch standoff adapter for medium-reach applications.
