Product Overview

The Bently Nevada 330103-00-13-10-12-00 3300 XL 8mm Proximity Probe serves as a cornerstone for industrial machinery protection, delivering high-fidelity shaft vibration and position data. Engineered for the demanding environments of steam turbines, centrifugal compressors, and large electric motors, this eddy current sensor provides non-contact measurement with exceptional linearity. It detects minute movements in rotating shafts without physical contact, ensuring zero mechanical wear while maintaining sub-micron precision. This specific configuration features a robust M10x1 metric thread and a FluidLoc® cable, which prevents oil and other process fluids from leaking through the cable's interior. By integrating this probe into your Turbine Supervisory Instrumentation (TSI), you gain a critical early warning system against catastrophic mechanical failure, extending the operational life of your most valuable assets.

Technical Configuration Details

The model number 330103-00-13-10-12-00 defines the specific mechanical and electrical properties required for precise field installation:

Unthreaded & Overall Case Length (-00-13)

The "00" indicates a 0mm unthreaded length, meaning the probe body is fully threaded for maximum adjustment flexibility. The "13" specifies a 130mm overall case length, providing significant reach through machine housings or bearing caps to access the target shaft.

Total Length (-10)

The "10" designation confirms a 1.0-meter total cable length. This is the standard length for probes intended to be connected to an extension cable before reaching the Proximitor® Sensor.

Connector and Agency Approval (-12-00)

The "12" suffix indicates the inclusion of a miniature coaxial ClickLoc™ connector with a silicone connector protector. The FluidLoc® cable construction ensures that even if the probe tip is compromised, fluid cannot "wick" through the cable. The "00" confirms standard Agency Approvals for global industrial use.

Technical Specifications

Engineering Installation & Maintenance Guide

Gap Voltage Calibration

To ensure accurate vibration readings, engineers must set the mechanical "Gap" between the probe tip and the target shaft. Using a voltmeter, monitor the output at the Proximitor® Sensor. For a 3300 XL 8mm system, the standard center-gap setting is -10.0 VDC, which corresponds to the midpoint of the sensor's linear range.

Cable Routing and Bend Radius

The coaxial cable must not be kinked during installation. Maintain a minimum bend radius of 25.4 mm (1 inch). Use conduit or cable trays to protect the lead from mechanical damage, and always ensure the ClickLoc™ connectors are clean and dry before mating to prevent signal attenuation.

Material Compatibility

This probe is calibrated for AISI 4140 steel targets. If your shaft material differs significantly (e.g., stainless steel or plated materials), the scale factor will shift. Always verify target material compatibility during the engineering phase to maintain TSI accuracy.

Engineering Advantages

The 3300 XL 8mm probe outperforms standard sensors through its FluidLoc® technology, which acts as a secondary seal against high-pressure oil environments. Its ClickLoc™ connectors provide a positive-lock mechanism that resists vibration-induced loosening, a common failure point in older designs. Furthermore, the probe maintains complete backward compatibility with non-XL Bently Nevada systems, allowing for seamless upgrades of aging 3300 series monitors without requiring expensive re-drilling of machine casings.

Technical FAQs

Q1: How do I know if the probe is too close to the shaft during installation?

A1: Monitor the DC voltage. If the voltage is more positive than -2.0 VDC, the probe is likely touching the shaft or is dangerously close. Standard operating range starts around -4.0 VDC to -16.0 VDC.

Q2: What is the benefit of the FluidLoc® cable?

A2: FluidLoc® prevents process fluids (like oil) from migrating through the inside of the cable. This protects your junction boxes and Proximitor® sensors from oil contamination, which is a leading cause of signal drift.

Q3: Can this probe be used with a 5-meter or 9-meter system?

A3: This probe has a 1.0m lead. It must be paired with the correct extension cable to match the total system length (usually 5m or 9m) for which the Proximitor® is calibrated. Check your Proximitor® label to confirm the required system length.

Q4: Is the M10 thread interchangeable with 3/8-24 threads?

A4: No. This is a metric M10x1 thread. Attempting to force it into an imperial 3/8-24 hole will damage the machine casing and the probe threads. Always verify your mounting port threads before installation.
