Product Overview

The Bently Nevada 330101-00-41-10-02-05 stands as the gold standard in eddy current transducer technology, specifically designed for the 3300 XL 8mm Proximity Transducer System. This probe provides high-fidelity measurements of radial vibration, axial position (thrust), and speed on critical rotating machinery. By delivering a voltage output directly proportional to the distance between the probe tip and the shaft, it enables the Bently Nevada 3500 system and Honeywell Experion PKS to perform real-time diagnostics and emergency shutdown (ESD) functions. Its robust construction ensures reliable performance in the most punishing industrial environments, including utility-scale steam turbines, high-pressure compressors, and large-scale induction motors, protecting billion-dollar assets from mechanical failure.

Hardware Configuration Decoding

330101 - 3300 XL 8mm Probe (3/8-24 UNF thread)

This base model identifies the standard 8mm tip diameter probe with inch-standard 3/8-24 UNF mounting threads, ensuring compatibility with standard industrial housing assemblies.

-00-41-10 - Physical Dimensions

The "-00" suffix confirms a 0.0-inch unthreaded length, indicating the body is fully threaded for maximum mounting flexibility. The "-41" designates a 4.1-inch overall case length, while the "-10" specifies a 1.0-meter (3.3 ft) integral probe cable.

-02-05 - Connector and Global Approvals

The "-02" option features a miniature coaxial connector with a factory-installed connector protector to shield the junction from oil and moisture. The "-05" suffix provides multiple global agency approvals, including CSA, ATEX, and IECEx, for use in Zone 0, 1, and 2 hazardous areas.

Core Technical Specifications

On-Site Installation Protocol

Engineers must prioritize precision "Gap Voltage" settings during commissioning. Utilizing a digital multimeter, adjust the probe's physical distance from the shaft until the Proximitor output reads exactly -10.0 Vdc. This voltage represents the center of the 80-mil linear range, allowing for maximum shaft movement without signal clipping. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the integral cable to prevent coaxial shield fatigue. Always ensure the -02 connector protector is slid firmly over the coaxial junction to prevent conductive fluids from shorting the high-frequency measurement signal.

Advanced Asset Protection Performance

The 330101-00-41-10-02-05 utilizes a hermetically sealed tip molded to the stainless steel probe body, providing an impenetrable barrier against corrosive synthetic lubricants and high-pressure steam. This design eliminates "thermal drift," a common issue where temperature fluctuations cause false vibration readings. By providing a stable, low-noise signal to Turbine Supervisory Instrumentation (TSI), it allows for advanced diagnostic techniques such as orbit plots and shaft centerline analysis. This probe integrates seamlessly into existing Bently Nevada 3500 racks, ensuring your facility maintains the highest E-E-A-T standards in machinery protection and operational safety.

Technical Consultation FAQs

Q1: Can I use this probe with an older 3300 Proximitor?

A1: Yes, the 3300 XL probes are backward compatible with standard 3300 Proximitors, although we recommend the XL series Proximitor to maximize thermal stability and linear range performance.

Q2: What target material is this probe calibrated for?

A2: Like most 3300 XL probes, this model is factory-calibrated for AISI 4140 steel targets. If your shaft material differs significantly, a scale factor adjustment may be necessary in your 3500 monitor.

Q3: Is the 4.1-inch case length (-41) adjustable?

A3: The overall case length is fixed. However, because this model is fully threaded (-00 unthreaded), you have complete flexibility in how deep it is mounted within the housing or bracket.

Q4: How do I handle a "Not OK" status on the vibration monitor?

A4: First, check the gap voltage. If it is less than -1V or greater than -19V, the probe is likely out of range. If the voltage is 0V, inspect the cable for a short or a disconnected junction.
