Technical Specifications

Suffix Code Explanation

Core Advantages

1. Industry-Standard Reliability

The 3300 XL series is Bently Nevada's premier proximity probe system, used for all installations except when spare parts are required on legacy systems . Its proven eddy-current technology delivers accurate, repeatable measurements for critical machinery protection and condition monitoring .

2. Modular Interchangeability

The 3300 XL system's probes, extension cables, and Proximitor sensors are electrically and mechanically interchangeable. Parts can be swapped without matching or calibration, dramatically simplifying maintenance and reducing downtime .

3. Robust Armored Construction

The stainless steel armor protects the probe cable from mechanical abrasion, cuts, and nicks that can occur during installation or operation in tight machinery housings. The patented TipLoc™ molding method provides a stronger bond between the probe tip and body .

4. ClickLoc™ Connector Reliability

The gold-plated ClickLoc™ connector requires only finger-tight torque (you feel a "click" when tight) and features a patented locking mechanism to prevent loosening from vibration. No special tools are required for installation or removal .

5. Wide Environmental Tolerance

With an operating temperature range of -52°C to +177°C, this probe handles the extreme thermal conditions found in steam turbines and other high-temperature machinery .

Applications

The 330104-06-12-10-02-00 is deployed across a broad spectrum of critical rotating machinery applications:

Primary Measurement Functions

• Radial Vibration – Shaft relative vibration measurement 

• Axial Position (Thrust) – Monitoring rotor axial displacement

• Keyphasor® Reference – Phase/speed reference for balancing and diagnostics 

System Integration Notes

The 3300 XL System is a Matched Set

A complete 3300 XL measurement system consists of three parts that are precisely matched as a calibrated set :

1. Proximity Probe (this item) – Mounts inside the machine, facing the shaft

2. Extension Cable – Links the probe to the Proximitor Sensor (e.g., 330130 series)

3. Proximitor Sensor – Powers the probe and converts the signal to a usable output (e.g., 330180 series)

Important: For accurate readings, the total system electrical length (probe + extension cable) must match the Proximitor Sensor's design length, typically 5 or 9 meters. Do not mix parts from different systems or manufacturers .

Mounting

• Thread: M10 × 1 metric 

• Recommended Gap: Set to -9 Vdc at 1.27 mm 

• Wrench Flats: 8 mm for M10 threads

Frequently Asked Questions (FAQ)

Q1: What is the Bently Nevada 330104-06-12-10-02-00?

It is an 8 mm proximity probe from the 3300 XL series, used for non-contact measurement of shaft vibration and position in industrial rotating machinery .

Q2: What does each suffix in the part number mean?

06 = 60 mm unthreaded length; 12 = 120 mm case length; 10 = 1.0 meter total length; 02 = Miniature ClickLoc™ connector with standard cable; 00 = No agency approval required .

Q3: What is the total cable length of this probe?

The total length is 1.0 meter (3.3 feet) .

Q4: Is this probe armored?

Yes, this variant includes stainless steel armor on the cable for mechanical protection .

Q5: What thread type does this probe use?

It uses an M10 × 1 metric thread .

Q6: What is the linear range and sensitivity?

The linear range is 2 mm (80 mils) with a sensitivity of 7.87 V/mm (200 mV/mil) .

Q7: What is the operating temperature range?

The probe operates from -52°C to +177°C (-62°F to +351°F) .

Q8: What is the minimum shaft diameter this probe can measure?

The minimum recommended shaft diameter is 50.8 mm (2 inches) .

Q9: What connector does this probe have?

It features a Miniature Coaxial ClickLoc™ connector .

Q10: Does this probe require a specific extension cable and Proximitor?

Yes. The 3300 XL system requires matching parts with a total electrical length of 5 or 9 meters. Do not mix with parts from other systems or manufacturers .

Q11: Can I use this probe without an extension cable?

This probe has an integral 1.0 m cable. To connect to a Proximitor sensor, you will need an extension cable (e.g., 330130 series) to reach the required total system length. The total probe + extension cable length must match the Proximitor's design length .

Q12: What is the recommended gap setting?

The recommended gap is set to -9 Vdc at 1.27 mm .
