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. 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.
3. 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.
4. 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.
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.
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:
-
Proximity Probe (this item) – Mounts inside the machine, facing the shaft
-
Extension Cable – Links the probe to the Proximitor Sensor
-
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 matching a 9.0 m Proximitor sensor.
Mounting
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
-
Ground the shield at the signal conditioner end only to prevent ground loops
Applications

Frequently Asked Questions (FAQ)
Q1: What is the Bently Nevada 330101-00-16-10-02-00?
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 3/8-24 UNF threading and a standard unarmored cable.
Q2: What does each suffix in the part number mean?
00 = 0.0 in unthreaded length; 16 = 1.6 in 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?
No. This is the unarmored variant. The 330102 model number would indicate an armored version with the same threading.
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 a 3/8-24 UNF thread.
Q6: What is the linear range and sensitivity?
The linear range is 0.25–2.3 mm (10–90 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.
Q10: Can I use this probe with older 3300 series systems?
Yes. The 3300 XL 8 mm probes are backward-compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components.
Q11: What is the recommended gap setting?
The recommended gap is set to -9 Vdc at 1.27 mm.
Q12: Is this probe suitable for hazardous areas?
This specific variant (suffix 00) has no agency approval for hazardous areas. If hazardous area certification is required, select a probe variant with the appropriate agency approval suffix.
