Bently Nevada 330104-05-10-10-02-CN 3300 XL 8 mm Proximity Probe

Reliable Vibration Monitoring for Critical Machinery

When unexpected machine downtime disrupts production, the Bently Nevada 330104-05-10-10-02-CN 3300 XL 8 mm proximity probe provides the precise, non-contact measurements needed for early fault detection. This probe is engineered for continuous monitoring of shaft vibration and position in rotating equipment such as turbines, compressors, and pumps.

Technical Specifications

The 330104-05-10-10-02-CN features an M10 x 1 threaded design with armor for enhanced durability in harsh environments. Its unthreaded length is 5 mm, overall case length is 100 mm, and total length is 1.0 meter (3.3 feet). The connector uses a miniature coaxial ClickLoc design with standard cable. The probe tip is made of polyphenylene sulfide (PPS) and the case is AISI 303 or 304 stainless steel. Nominal probe DC resistance is 7.59 ± 0.50 ohms for the 1.0 meter length.

Solving Real-World Monitoring Challenges

In many industrial plants, inaccurate or drifting proximity probe readings lead to false alarms or missed faults. The 330104-05-10-10-02-CN addresses this with a robust design that seals differential pressure between the probe tip and case using a Viton O-ring. This ensures stable performance even in environments with oil mist, moisture, or temperature variations. For example, in a steam turbine application, this probe delivers consistent gap voltage readings, enabling operators to detect early bearing wear before catastrophic failure occurs.

Installation and Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe so that the target surface is perpendicular to the probe axis. Use the M10 x 1 thread to secure it in a suitable mounting bracket. Ensure the probe tip is gapped at 1.27 mm (50 mils) for optimal linear range when used with an AISI 4140 steel target. The miniature coaxial ClickLoc connector simplifies cable attachment and provides a secure, vibration-resistant connection.

Maintenance and Reliability

Regular inspection of the probe tip and cable for physical damage is recommended. The PPS tip resists chemical attack, and the stainless steel case withstands corrosion. Because the probe is sealed, no internal cleaning is required. Verify that the extension cable and Proximitor sensor are compatible 3300 XL 8 mm components to maintain system accuracy. Periodic calibration checks against a known target help ensure long-term reliability.

Compatibility and Integration

The 330104-05-10-10-02-CN is part of the 3300 XL 8 mm system and accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe and extension cable. It requires a power supply of -17.5 Vdc to -26 Vdc (or -23 Vdc to -26 Vdc with barriers) at 12 mA maximum consumption. The output resistance is 50 ohms. For best results, use only genuine Bently Nevada components to maintain system accuracy and interchangeability.
