Product Description
The Bently Nevada 330105-02-12-90-02-00 is part of the 3300 XL 8 mm Reverse Mount Proximity Probe series. This probe is designed to detect the distance between the probe tip and a conductive target surface, delivering accurate dynamic (vibration) and static (position) measurements. It is reverse-mounted for applications requiring installation from the opposite side of the target surface.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of the 330105-02-12-90-02-00 probe?
A1: It measures shaft vibration and position in rotating machinery using eddy current technology.
Q2: Can this probe be used with any 3300 XL extension cable?
A2: Yes, as long as the combined probe and cable length matches the required Proximitor system length.
Q3: Is the probe compliant with API 670?
A3: Yes, it fully complies with API 670 standards for mechanical configuration, accuracy, and stability.
Q4: What type of connector is used?
A4: It uses a gold-plated ClickLoc miniature coaxial connector that locks with finger torque.
Q5: Does this probe support reverse mounting only?
A5: Yes, it is specifically designed for reverse mounting applications.
Q6: Is it suitable for use in hazardous areas?
A6: Yes, it meets ATEX, IECEx, and CSA standards for hazardous zones with proper installation.
Q7: Can it operate at high temperatures?
A7: Yes, up to 177°C standard, or up to 218°C with ETR versions.
Q8: What happens if probe and extension cable lengths mismatch the Proximitor?
A8: System accuracy and linearity will be compromised; exact length matching is required.
Q9: Does the FluidLoc cable option come with this part number?
A9: No, this model uses the standard cable. FluidLoc is optional and specified differently.
Q10: Is this probe interchangeable with non-XL components?
A10: Yes, it is backward compatible with non-XL 3300 5 mm and 8 mm systems.
