Bently Nevada 330103-05-10-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

The 330103-05-10-10-02-CN is a high-precision, eddy-current proximity sensor from the Bently Nevada 3300 XL series. This 8 mm probe is specifically engineered for critical machinery protection within Turbine Supervisory Instrumentation (TSI) frameworks. It provides non-contacting displacement measurements for vibration, position, and speed in high-speed rotating equipment. Extensively utilized in power generation, oil refineries, and large-scale manufacturing, this probe is essential for monitoring shaft vibration and axial thrust. By delivering accurate data to 3500 series monitoring systems, the 330103-05-10-10-02-CN enables operators to detect mechanical anomalies early, preventing catastrophic failure and minimizing expensive unscheduled downtime.

Specifications

FAQs

Does the "CN" suffix affect the electrical performance of the probe?

No, the CN suffix refers to regional agency approvals and certifications. The electrical characteristics, including frequency response and scale factor, remain identical to the standard 3300 XL 8 mm probe specifications.

How does the ClickLoc connector prevent signal loss in high-vibration environments?

The ClickLoc connector features a gold-plated, locking coaxial design that ensures a constant, low-resistance connection. Unlike traditional connectors, it is designed to resist loosening due to high-frequency machinery vibration, maintaining signal integrity without the need for manual retightening.

Can this probe be used with non-XL Proximitor Sensors?

While the 3300 XL 8 mm probe is backward compatible with some older 3300 Proximitor sensors, it is not recommended. For the system to meet its published accuracy and temperature specifications, it should be used exclusively with a 3300 XL Proximitor and the correct length extension cable.

Engineering & Guide

• Gap Voltage Setting: During installation, the probe must be "gapped" to the center of its linear range. Connect the probe to the Proximitor and adjust the physical distance from the target until the DC output voltage reads approximately -10 VDC. This ensures maximum headroom for both positive and negative displacement measurement.

• Installation Torque: For the M10 x 1 threads, do not exceed the maximum allowable torque of 7.5 Newton-meters (66 in-lb). Over-tightening can cause internal stress on the PPS probe tip or the stainless steel case, leading to premature failure or signal drift.

• Target Material Calibration: The probe is factory-calibrated for AISI 4140 steel. If the target shaft is composed of a different material (e.g., stainless steel or aluminum), the scale factor will change significantly. In such cases, the monitoring system must be recalibrated to the specific material properties.

• Cable Protection: Ensure the 1.0-meter probe lead is protected from sharp edges and moving parts. Use flexible conduit where the cable exits the machine casing to prevent abrasion or cutting of the FEP insulation.
