Product Overview

The 330102-04-45-50-01-00 is a specialized 8 mm eddy-current transducer from the Bently Nevada 3300 XL family, specifically engineered for high-stress industrial environments. This probe functions as a non-contacting sensor that provides high-resolution data on shaft vibration and static displacement. Distinctive for its heavy-duty armored construction, this model is designed to safeguard the internal coaxial core against crushing, abrasion, and mechanical impact. With an integrated 5.0-meter cable and a robust threaded case, it serves as a critical front-end component for Turbine Supervisory Instrumentation (TSI) systems, ensuring continuous machine protection where standard, unarmored probes might fail.

Strategic Machine Monitoring Deployments

This armored proximity probe is ideally suited for heavy-duty rotating assets in refineries, power plants, and mining operations. It is frequently deployed on large steam turbines, high-pressure centrifugal pumps, and industrial gearboxes where external cables are exposed to foot traffic, falling debris, or high-vibration piping. The 330102-04-45-50-01-00 tracks radial vibration to identify early signs of rotor unbalance or misalignment and monitors axial thrust position to prevent catastrophic internal contact. Its extended 5-meter cable length allows for direct routing from the machine bearing housing to a remote junction box, simplifying the installation architecture while providing maximum mechanical defense for the signal path.

FAQ

Q: Why is the armored cable option significant for this probe?

A: The stainless steel armor provides a physical barrier that prevents the internal coaxial cable from being crushed or frayed. This is essential in harsh industrial zones where maintenance personnel may accidentally step on cables or where vibration could cause standard cables to rub against sharp metal edges.

Q: Can this probe be used for speed sensing applications?

A: Yes, the 330102-04-45-50-01-00 can function as a Keyphasor sensor. When aimed at a notch or keyway on a rotating shaft, it generates a pulse that the monitoring system uses to calculate RPM and the phase angle of vibration.

Q: Is a separate connector protector needed for this model?

A: No, the -01 suffix in this configuration indicates that the ClickLoc connector protector is already pre-installed. This ensures the connection to the extension cable is hermetically shielded from moisture and oil immediately upon installation.

Q: Does the 5.0-meter cable length require a specific extension cable?

A: Yes. Because this is a 5-meter probe, it is designed to connect directly to a 3300 XL Proximitor sensor without an extension cable in a "5-meter system" configuration. If an extension cable is added, the system would need to be re-calibrated for a 7-meter or 9-meter total length.

Q: What is the benefit of the 0.4-inch unthreaded section?

A: The unthreaded portion at the top of the case allows for easier insertion through mounting brackets or sleeves. It ensures that the threads engage smoothly without cross-threading when the probe is being positioned near the shaft.
