Frequently Asked Questions (FAQ)

Q1: What is the maximum penetration depth for the Bently Nevada 24701-16-05-15-120-03-02?
A: This assembly provides a probe penetration of 12 inches (C dimension). The total visible (C)+(D) dimension reaches 13.5 inches maximum. The probe serial number remains not visible at full extension.

Q2: Can I use this housing with different cable sizes?
A: Yes. The cable seal grip includes three grommets for different diameters. You can choose 1/8 to 3/16 inches, 1/4 to 5/16 inches, or 5/16 to 3/8 inches. Select the correct grommet during installation.

Q3: What materials resist corrosion in this housing assembly?
A: The body uses 303 stainless steel for strength. The sleeve uses 304 stainless steel for additional corrosion resistance. This combination works well in humid or mildly corrosive environments.

Q4: Does the Bently Nevada 24701-16-05-15-120-03-02 include a standoff adapter?
A: The standoff adapter is optional. This specific suffix code (-15) means you ordered the minimum 1.5 inch length. If you see -00 instead, then no standoff adapter is included.

Q5: How do I access the probe after installation?
A: Simply unscrew the dome cover from the housing body. This gives you direct access to the reverse mount probe. You can then adjust the gap or replace the probe without removing the entire housing.
