Product details

Product Introduction: Bently Nevada 3300 XL 8mm Proximity Probe

This is the 330101-20-10-10-02-05, a premium 3300 XL 8mm Probe. It delivers precise vibration and position measurement for critical machinery. Its rugged 8mm design ensures long-term reliability. It is essential for predictive maintenance in industries like oil & gas and power generation.

Key Features & Benefits

Enhanced Durability: Thick 8mm probe body and patented TipLoc molding offer maximum resistance to physical damage and stress.
Reliable Connection: The CableLoc design guarantees a strong 75 lbf pull strength. This secures the cable and prevents signal failure.
Fluid Sealing Option: Choose the FluidLoc cable to block internal oil migration. It keeps fluids contained within your machine casing.
Stable Output: Probe performance remains stable in humid environments, with minimal change to the scaling factor.
Easy Setup: Comes pre-assembled with a 1-meter cable and ClickLoc connector for quick installation with 3300 XL systems.

Full Part Number: 330101-20-10-10-02-05

330101 – 3300 XL 8 mm Probe, 3/8-24 UNF thread
-20 – Unthreaded Length: 2.0 inches
-10 – Overall Case Length: 1.0 inch
-10 – Total Length: 1.0 meter (3.3 feet) cable
-02 – Connector: Miniature coaxial ClickLoc
-05 – Agency Approval: Not required (00 standard, 05 denotes specific order variant)

Measurement Range: 2.0 mm (80 mils) linear range, starting 0.25 mm from target.
Recommended Gap: -9 Vdc for radial vibration (approx. 1.27 mm / 50 mils).
Sensitivity (ISF): 7.87 V/mm (200 mV/mil) ±5% (5/1m system).
Linearity (DSL): Better than ±0.025 mm (±1 mil) (5/1m system).
Frequency Response: Supports long cable runs up to 305 meters with proper shielded wiring.
Temperature Range:
- Standard: -52°C to +177°C (-62°F to +350°F).
- Extended (ETR): Tip to +218°C (+425°F).
Environmental: PPS tip, stainless steel case. Resists oils, chemicals, and 93% humidity.
Probe Resistance: 7.59 Ω ±0.50 Ω (1.0m length).

Applications: Ideal for turbines, compressors, pumps, and fans to monitor shaft vibration and position.
Diagnostics: Enables detection of machine faults like unbalance, misalignment, and bearing issues.

Frequently Asked Questions (FAQ)

Why choose an 8mm probe over a 5mm?

The 8mm probe is significantly more robust. It better withstands accidental contact and harsh environments, reducing failure risk.

Can I use this probe in a hot application?

Yes. The standard version suits most applications. For temperatures above 177°C (350°F) at the tip, select the Extended Temperature Range (ETR) option.

How does FluidLoc work?

The FluidLoc option adds a special seal along the cable’s interior. It stops pressurized oil from traveling through the cable and leaking outside the machine.

Is the probe’s pressure seal certified?

No. Probes are not routinely pressure tested. For seal validation in pressure-containing applications, you must request special testing.

What is the consequence of over-torquing?

Over-torquing can damage the probe case threads or the mounting thread in your equipment. Always use a calibrated torque wrench.

I need a different cable length or connector. What should I do?

The part number suffix determines length and connector. Contact us with your requirements. We can help source the correct configuration (330101-20-10-10-02-05).
