Technical Specifications

Suffix Code Explanation

Core Advantages

1. Industry-Standard Reliability

The 3300 XL series is Bently Nevada's premier proximity probe system, delivering the most advanced performance in eddy current proximity transducer systems. It fully complies with API 670 Standard (4th Edition) for mechanical configuration, linear range, accuracy, and temperature stability .

2. Armored Protection for Harsh Environments

The armored cable construction shields the internal triaxial conductor from physical damage, abrasion, and compression. This makes the 330104-10-19-10-02-00 ideal for installations where cables are exposed to mechanical stress, foot traffic, or high-vibration machinery housings .

3. 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 bench calibration, simplifying maintenance and reducing spare parts inventory .

4. ClickLoc™ Connector Reliability

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

5. Robust Sealing Technology

The Viton® O-ring seals differential pressure between the probe tip and case, preventing oil leakage and ensuring reliable operation in lubrication-rich environments such as turbines and compressors .

6. 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 .

System Integration Notes

The 3300 XL System is a Matched Set

A complete 3300 XL measurement system consists of three parts that must have consistent electrical lengths :

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

2. Extension Cable – Links the probe to the Proximitor Sensor

3. Proximitor Sensor – Powers the probe and converts the signal to a usable output

Important: The total system electrical length (probe length + extension cable length) must equal the Proximitor Sensor's design length (typically 5 or 9 meters). For this 1.0 m probe, it is typically paired with an 8.0 m extension cable to create a 9.0 m system . Mismatched components may cause measurement errors of 20% or greater.

Mounting

• Thread: M10 × 1 metric

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

• Minimum Shaft Diameter: 50.8 mm (2 in) 

Wiring Requirements

• Route cables away from high-voltage power lines to minimize electromagnetic interference

• Maintain minimum bend radius to prevent damage to the coaxial core

• Secure armored cables using suitable clamps to prevent vibration-induced wear

Applications

The 330104-10-19-10-02-00 is deployed across critical rotating machinery applications :

Frequently Asked Questions (FAQ)

Q1: What is the Bently Nevada 330104-10-19-10-02-00?

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. This variant features M10 × 1 metric threading, an extended 100 mm unthreaded length, and an armored cable for mechanical protection .

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

10 = 100 mm unthreaded length; 19 = 190 mm case length; 10 = 1.0 meter total length; 02 = Miniature ClickLoc™ connector with standard cable; 00 = No agency approval required .

Q3: Is this probe armored?

Yes, the 330104 model number indicates an M10 × 1 metric-threaded probe with armored cable. The armor provides stainless steel protection for the cable in harsh environments .

Q4: What is the total cable length of this probe?

The total length is 1.0 meter (3.3 feet) .

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) when used with a 3300 XL Proximitor sensor .

Q7: What is the operating temperature range?

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

Q8: What connector does this probe have?

It features a Miniature Coaxial ClickLoc™ connector with gold plating. These require only finger-tight torque and feature a locking mechanism .

Q9: 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. For this 1.0 m probe, pair with an 8.0 m extension cable to create a 9.0 m system matching a 9.0 m Proximitor sensor .
