Bently Nevada 330106-05-30-10-02-00 | 3300 XL 8mm Reverse Mount Proximity Probe

Description

The Bently Nevada 330106-05-30-10-02-00 is a high-performance 8mm reverse-mounted eddy current probe, a vital component of Bently Nevada’s industry-leading 3300 XL sensor system. Specifically engineered for the rigorous demands of heavy industry, the Bently 330106-05-30-10-02-00 is designed to provide highly accurate, non-contact measurement of shaft relative vibration, axial displacement (thrust position), and Keyphasor reference signals. As a reverse-mount sensor, it is installed from the back of the machinery casing, making it the ideal solution for machines with limited external access or where the probe must be protected from the external environment.This probe operates on the eddy current principle, converting physical displacement into a precise electrical signal that is transmitted to a monitoring system like the Bently Nevada 3500 series. The Bently 330106-05-30-10-02-00 features a robust M10x1 threaded, armored casing and comes with a 1-meter integrated cable. It is fully compliant with the American Petroleum Institute (API) 670 standard, ensuring it meets the strictest requirements for machinery protection systems in critical applications such as power generation, oil & gas, and chemical processing.

Technical Specifications

Main Features and Advantages

API 670 compliant precision. The Bently 330106-05-30-10-02-00 is manufactured to meet the stringent API 670 standard, which is the benchmark for vibration and axial position monitoring in the petrochemical and power industries. This ensures that the probe delivers the high accuracy, linearity, and temperature stability required to protect multi-million dollar rotating assets from catastrophic failure.Robust reverse-mount design. The reverse-mount configuration of the Bently 330106-05-30-10-02-00 allows for installation through the machine casing from the interior side. This is a critical feature for applications where external space is constrained, or where the probe needs to be shielded from harsh external conditions, physical damage, or high-velocity fluids. Its armored construction and M10x1 thread provide a secure and durable mounting solution.Interchangeability and system reliability. A major advantage of the 3300 XL system is the complete interchangeability of its components. The Bently 330106-05-30-10-02-00 probe, along with its corresponding extension cable and proximitator, does not require individual bench calibration or matching. This plug-and-play capability drastically simplifies inventory management and reduces maintenance time during replacements, minimizing costly operational downtime.Secure and protected connections. The probe features Bently’s proprietary ClickLoc™ gold-plated copper connector, which can be finger-tightened and includes a mechanical lock to prevent loosening from vibration. Additionally, the Bently 330106-05-30-10-02-00 utilizes CableLoc™ design to securely anchor the cable to the probe body, and the FluidLoc™ cable option prevents oil or other process liquids from migrating along the cable interior and damaging the connections.

Application Field

Turbomachinery monitoring. The Bently 330106-05-30-10-02-00 is a cornerstone of machinery protection systems for critical turbomachinery. It is extensively used to monitor the shaft vibration and axial displacement of steam turbines, gas turbines, and hydroelectric generators, providing the real-time data needed to prevent rubs, blade failures, and thrust bearing damage.Oil & gas and chemical processing. In refineries and chemical plants, the reliability of rotating equipment is paramount. The Bently 330106-05-30-10-02-00 is deployed on centrifugal and axial compressors, as well as large pumps and expanders. Its ability to operate reliably in harsh environments ensures continuous monitoring of equipment health, helping to avoid unscheduled shutdowns and maintain process safety.General industrial rotating equipment. Beyond the most critical assets, this versatile probe is also used on a wide range of industrial machinery, including large fans, blowers, gearboxes, and motors. By providing early warnings of imbalance, misalignment, or bearing wear, the Bently 330106-05-30-10-02-00 enables predictive maintenance strategies that extend equipment life and optimize operational efficiency.

Installation and Maintenance

Pre-installation preparation: Before installing the Bently 330106-05-30-10-02-00, ensure the machinery is safely shut down and locked out. Verify that the mounting hole is clean, properly sized for the M10x1 thread, and free of burrs. You will need the appropriate wrench for installation, and it is crucial to connect the probe to its correct extension cable and proximitator to form a complete, calibrated system. Ensure the target measurement surface on the shaft is clean and free of scratches or plating.Maintenance recommendations: The Bently 330106-05-30-10-02-00 is a solid-state device with no moving parts, requiring minimal maintenance. However, periodic visual inspections of the cable and connector are recommended to check for physical damage, oil ingress, or corrosion. Ensure the gap voltage (the DC voltage representing the distance between the probe tip and the shaft) is within the recommended linear range (typically around -10 VDC for a 1.27 mm gap). If a replacement is necessary, the interchangeability of the 3300 XL system allows for a direct swap without recalibration.
