Bently Nevada 330104-00-13-10-02-CN Retrofit Probe for 3300 XL

Bently Nevada 330104-00-13-10-02-CN Retrofit-Ready Proximity Probe for 3300 XL Control Systems

The Bently Nevada 330104-00-13-10-02-CN is an 8mm proximity probe engineered for seamless compatibility with the 3300 XL Series vibration monitoring platform. As legacy 3300 Series installations approach end-of-life or require spare-part replenishment, this probe serves as a verified retrofit-ready replacement that preserves existing wiring, conduit routing, and signal chain integrity without requiring modifications to the monitor rack or field junction boxes.

Whether you are executing a planned control system upgrade, recovering from an unplanned shutdown, or building a critical-spares inventory for a continuous-process facility, the 330104-00-13-10-02-CN delivers the dimensional accuracy, gap voltage linearity, and EMI shielding required by Bently Nevada’s 3300 XL proximity transducer system specifications. The probe is compatible with the standard 3300 XL extension cable assemblies and the 3300 XL proximitor/seismic transducer, allowing technicians to complete a field swap within a single maintenance window.

Retrofit Planning for Existing Automation Systems

A successful retrofit of the 330104-00-13-10-02-CN into an operating plant begins well before the maintenance window opens. Engineers should pull the existing loop drawing to confirm the proximitor model — typically a 3300 XL Proximitor/Seismic transducer — and verify that the 330130-series extension cable routed through the conduit is undamaged and correctly terminated at the field junction box. If the extension cable shows signs of insulation breakdown or connector corrosion, it should be replaced concurrently with the probe to avoid a repeat outage.

At the monitor rack, confirm that the 3500/40M Proximitor Monitor or 3500/42M Proximitor Monitor card is configured for the correct transducer type and gap range. The rack’s 3500/15 Power Supply module should be verified for adequate current headroom before adding any replacement transducer to the loop, particularly in dense rack configurations where multiple 3500-series I/O modules share a single backplane. If the facility is migrating from an older 3300/16 or 3300/20 card to a 3500-series rack, the channel configuration in System 1 Evolution software must be updated to reflect the new transducer sensitivity and OK limits.

For plants running a DCS backbone — such as a Honeywell Experion PKS or Emerson DeltaV — the vibration data from the 3500 rack is typically forwarded via Modbus RTU or OPC DA to the process historian. Confirm that the tag mapping and engineering-unit scaling remain consistent after the probe swap; a sensitivity mismatch between the old and new probe can shift the vibration amplitude reading and trigger nuisance alarms or, worse, mask a genuine machinery fault. If the facility uses a 3500/92 Communication Gateway Module, verify that the Modbus register map does not require re-mapping after the channel reconfiguration.

Where the original installation used a 9000-series probe in an older Bently Nevada rack, the migration path to the 3300 XL system requires a full transducer system change — probe, extension cable, and proximitor — along with a recalibration of the OK voltage window. In these cases, the 330104-00-13-10-02-CN is the correct starting point for the probe selection, and the project scope should include updated loop drawings, revised alarm setpoints in the 3500 rack configuration, and a functional acceptance test witnessed by the reliability engineer before the machine is returned to service.

Downtime Control During System Migration

Minimizing unplanned downtime during a proximity probe replacement requires a structured pre-outage checklist and a clearly defined return-to-service sequence. Before the machine is taken offline, technicians should download and archive the current 3500 rack configuration using Rack Configuration software, preserving all channel setpoints, alarm thresholds, and transducer sensitivity values. This archived configuration serves as the baseline for post-swap verification and provides a rapid restore path if the new probe exhibits an unexpected gap voltage deviation.

During the swap, the existing probe should be removed carefully to avoid disturbing the extension cable connector at the proximitor input. The 330104-00-13-10-02-CN should be threaded into the probe holder by hand before torquing to the specified value, and the gap should be set using a non-ferrous feeler gauge or a calibrated gap-setting tool referenced to the shaft surface. Once the gap is set, the OK voltage should be confirmed at the proximitor terminal before the monitor card is re-enabled, preventing a false-trip condition that could delay restart.

If the facility operates under a safety instrumented system that interlocks on vibration, coordinate with the SIS engineer to place the affected channel in bypass mode for the duration of the swap and restore it only after the OK relay has been confirmed healthy. Maintaining a written bypass log and obtaining the required management-of-change approval before the outage begins will keep the migration compliant with IEC 61511 requirements and protect the facility’s functional safety record. With proper preparation, a single-probe replacement on a 3300 XL or 3500-series system can typically be completed and verified within two to four hours, keeping the impact on production schedules to a minimum.

Retrofit Support FAQ

Q1: Is the 330104-00-13-10-02-CN a direct replacement for the original Bently Nevada part of the same number?
Yes. This unit is manufactured to the same dimensional and electrical specification as the original 330104-00-13-10-02-CN and is a verified drop-in replacement. No modifications to the probe holder, extension cable, or proximitor are required, and no firmware changes are needed on the 3500/40M or 3500/42M monitor card.

Q2: What commissioning steps are required after installation?
After threading the probe to the correct gap distance, measure the DC gap voltage at the proximitor output terminals. The nominal target is −10.0 VDC ± 0.5 V at a 1.0 mm gap on a standard steel shaft. Confirm that the OK LED on the proximitor is illuminated and that the monitor card is not in an alarm or danger state before re-enabling the channel and releasing the machine to operations.

Q3: Can this probe be used with extension cables other than the Bently Nevada 330130 series?
The 330104-00-13-10-02-CN is calibrated as a system with the 330130-series extension cable and the 3300 XL proximitor. Using a non-standard extension cable will alter the total system capacitance and resistance, shifting the gap voltage curve and potentially causing the OK circuit to report a false fault. Always use the matched extension cable specified in the original loop drawing to maintain system accuracy and warranty coverage.

Q4: What does the 12-month warranty cover, and is a test report included?
The 12-month warranty covers manufacturing defects in materials and workmanship from the date of shipment. Each unit undergoes a pre-shipment functional test that verifies gap voltage linearity, OK relay operation, and cable continuity. A test report is available upon request and can be provided with the shipment documentation to support incoming inspection and maintenance records.
