Bently Nevada 330101-00-13-15-02-CN 3300 XL Replacement

Product Overview

Bently Nevada 330101-00-13-15-02-CN 3300 XL Replacement: Seamless Transition & Legacy System Upgrade

The Bently Nevada 330101-00-13-15-02-CN is an 8mm eddy-current proximity probe engineered for the 3300 XL Series vibration monitoring platform. As rotating machinery protection systems age and OEM support for legacy transducer assemblies is phased out, plant engineers and reliability teams face increasing pressure to source direct replacements that preserve existing wiring infrastructure, connector pinouts, and monitor channel calibration — without triggering a full system re-qualification. This product is stocked and tested to meet that exact requirement.

Whether you are replacing a failed probe in a critical turbine train, upgrading a worn transducer assembly on a compressor skid, or consolidating spare-parts inventory ahead of a planned outage, the 330101-00-13-15-02-CN integrates directly into your existing 3300 XL monitoring loop. The 8mm probe tip, 5-metre armoured cable, and standard Bently Nevada connector interface are dimensionally and electrically compatible with the original factory specification, allowing drop-in installation without re-routing conduit or modifying junction boxes.

Seamless Upgrade Solutions

A successful proximity probe replacement rarely involves the probe alone. In practice, the 330101-00-13-15-02-CN is deployed as part of a broader transducer assembly that includes the Bently Nevada 330130 extension cable — the armoured interconnect that bridges the probe to the monitor rack. If the extension cable shows signs of insulation breakdown or connector corrosion, replacing it alongside the probe eliminates a common source of intermittent gap voltage drift. The extension cable connects at the field junction box and routes back to the 3300 XL monitor module installed in the control room rack, typically a 3300/16 Dual Voting or 3300/20 Radial Vibration card depending on your machinery protection architecture.

For plants running a full Bently Nevada System 1 condition monitoring platform, the probe signal feeds into the 3500/42M Proximitor/Seismic Monitor or the legacy 3300/25 Keyphasor module, both of which accept the standard -24 VDC eddy-current output without signal conditioning changes. If your site is migrating from an older 7200 Series transducer system to the 3300 XL platform, note that the driver electronics differ: the 3300 XL Proximitor sensor integrates the oscillator-demodulator circuit within the probe body, whereas the 7200 Series uses a separate driver module. This architectural difference means the 330101-00-13-15-02-CN is not a plug-in replacement for 7200 Series probes without also replacing the associated driver.

In control cabinet environments where space is constrained, the compact form factor of the 330101-00-13-15-02-CN allows installation in tight bearing housing clearances typical of steam turbines and centrifugal compressors. When the monitoring loop also includes a Keyphasor probe (commonly a 330180 or 330105 model) for phase reference, ensure the Keyphasor gap is re-verified after any probe replacement on the same shaft to maintain accurate speed and phase measurements across the 3500 rack. For sites using a Bently Nevada TDXnet or System 1 Evolution data acquisition node, no software reconfiguration is required — the channel simply resumes data collection once the replacement probe is gapped and the monitor is reset.

Procurement teams consolidating spare-parts kits for planned turnarounds often pair the 330101-00-13-15-02-CN with a 330130-080-00-00 extension cable, a spare 3300 XL Proximitor driver, and a set of probe holders and lock nuts to ensure a complete field-replaceable unit is available on-site. This approach minimises the mean time to repair (MTTR) during unplanned outages and reduces dependency on expedited international freight during critical maintenance windows.

Retrofit Guidance FAQ

Q: Can I reuse the existing extension cable when replacing only the probe?
A: Yes, provided the 330130 extension cable passes a continuity and insulation resistance check. Inspect the coaxial connector at both ends for corrosion or mechanical damage. If the cable has been in service for more than five years in a high-vibration or high-temperature environment, replacement is recommended to avoid introducing a new fault source.

Q: Do I need to recalibrate the 3300 XL monitor after installing this probe?
A: In most cases, no. The 330101-00-13-15-02-CN shares the same sensitivity curve (7.87 V/mm) and gap voltage range as the original factory probe. However, best practice is to verify the static gap voltage at the monitor input after installation and confirm it falls within the linear range specified in the 3300 XL monitor manual (typically -10 VDC ± 1 VDC at the nominal air gap).

Q: Is this probe compatible with non-Bently Nevada monitors?
A: The 330101-00-13-15-02-CN is designed for the Bently Nevada 3300 XL Proximitor driver circuit. It can be used with third-party monitors that accept a -24 VDC powered eddy-current input with 200 mV/mil sensitivity, but compatibility must be verified against the third-party monitor’s input specification. No warranty coverage applies to non-standard configurations.

Q: What is the correct air gap for this probe?
A: The recommended installation gap for the 330101-00-13-15-02-CN on a standard AISI 4140 steel target is 1.0 mm (40 mil), corresponding to approximately -10 VDC output. Adjust the probe holder depth until the gap voltage reads within the monitor’s linear range, then lock the probe in position with the supplied lock nut.

Q: Can this probe be used for axial position measurement as well as radial vibration?
A: Yes. The 330101 family is suitable for both radial vibration and axial (thrust) position measurement applications, subject to the monitor channel being configured for the appropriate measurement type. Confirm the 3300 XL monitor card installed in your rack supports the intended measurement mode.

Q: What documentation is included with the shipment?
A: Each unit ships with an outgoing inspection report confirming electrical performance against the Bently Nevada factory specification, a calibration data sheet, and a certificate of conformance. Packaging is anti-static and moisture-protected for international freight.

Warranty Assurance

Every Bently Nevada 330101-00-13-15-02-CN supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a multi-point outgoing inspection that verifies probe tip integrity, cable continuity, connector condition, and static output voltage within the Bently Nevada factory specification. An inspection report is included with every shipment.

In the event of a confirmed defect within the warranty period, TOPNLMS will arrange a replacement unit or issue a credit note at the buyer’s discretion. Our after-sales response target is one business day for warranty claims submitted by email to [email protected]. Expedited replacement dispatch is available for critical plant applications where extended downtime is not acceptable.

Stock is held in Xiamen, China, with standard international dispatch within 2–3 business days of order confirmation. Express freight options (DHL, FedEx, UPS) are available for urgent requirements. All units are sourced through verified supply channels and are not refurbished or repaired stock unless explicitly stated at the time of quotation.
