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

Overview

Bently Nevada 330101-00-13-15-02-CN 3300 XL Probe: Migration-Ready Replacement for Legacy Vibration Monitoring Systems

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 original spare parts enter end-of-life, this probe serves as a verified drop-in replacement for facilities managing legacy Bently Nevada installations across turbines, compressors, pumps, and gearboxes in energy, petrochemical, and heavy manufacturing environments.

When planning a retrofit or spare-parts replenishment for an existing 3300 XL rack, engineers must confirm several critical parameters before installation. The 330101-00-13-15-02-CN operates with a standard 5-metre extension cable and requires a compatible Bently Nevada 3300 XL Proximitor® sensor — typically the 330180 series — to complete the measurement loop. The probe tip diameter is 8mm, and the recommended gap voltage at mid-range is −10 VDC, consistent with the 3300 XL system’s signal conditioning requirements. Verifying that the existing Proximitor housing, cable connector type, and rack slot assignment match the replacement probe specification is essential before powering down the monitored machine.

For sites running a Bently Nevada 3500 Series rack in parallel or as a migration target, the 330101-00-13-15-02-CN is also compatible with 3500/42M and 3500/45 monitor modules when paired with the appropriate Proximitor and extension cable assembly. This cross-series compatibility makes it a practical choice for phased migration projects where the 3300 XL rack is being decommissioned incrementally while the 3500 platform is brought online in stages.

Migration Compatibility Table

Retrofit Planning for Existing Automation Systems

A successful 3300 XL probe replacement begins well before the maintenance window opens. Site engineers should pull the existing rack configuration from the System 1 condition monitoring software or the legacy Bently Nevada Data Manager to confirm channel assignments, alert and danger setpoints, and the Keyphasor® reference channel mapping. If the plant is running a Bently Nevada 3300 XL rack alongside a newer 3500 Series frame, the channel-to-machine mapping must be reconciled across both platforms to avoid false trips during the cutover.

On the hardware side, the replacement 330101-00-13-15-02-CN probe must be paired with a serviceable 330180 Proximitor sensor. If the existing Proximitor shows signs of drift — indicated by a gap voltage outside the −7 to −18 VDC operating window — it should be replaced simultaneously to avoid masking a probe fault with a sensor fault. The extension cable assembly, typically a 330130 or 330140 series, should be inspected for jacket damage, connector corrosion, and continuity before reuse.

Power supply integrity is another pre-retrofit checkpoint. The 3300 XL rack’s internal power supply module — often a 3300/20 or equivalent — must deliver stable −24 VDC to the Proximitor circuit. A degraded power supply can introduce noise into the vibration signal and trigger nuisance alarms after the new probe is installed. Where the rack is being migrated to a 3500 platform, the 3500/15 power supply module should be verified for adequate current capacity to support all active monitor channels.

For I/O integration, confirm that the analogue output from the Proximitor is correctly wired to the DCS or safety instrumented system input card. If the plant uses a Rockwell Automation ControlLogix or Siemens S7-300 series PLC for auxiliary monitoring, the 4–20 mA signal from the Proximitor should be re-ranged and scaled in the PLC programme to match the new probe’s sensitivity factor. HMI screens built on Wonderware InTouch or Ignition SCADA should be updated to reflect the new probe tag name and engineering unit range before the system is returned to service.

Downtime Control During System Migration

Minimising unplanned downtime during a proximity probe replacement requires a structured pre-outage checklist and a clear rollback procedure. Before isolating the monitored machine, export the current rack configuration from the Bently Nevada configuration software and save a timestamped backup. This preserves all setpoint values, channel assignments, and Keyphasor settings so they can be restored immediately if the replacement probe does not perform within specification during initial commissioning.

During the physical swap, the probe gap should be set using a calibrated gap tool or a precision digital voltmeter measuring the Proximitor output voltage. The target gap for the 330101-00-13-15-02-CN at mid-range is −10 VDC ±0.5 VDC. Once the gap is confirmed, the rack channel should be brought online in bypass mode — if the 3500 platform supports it — so that the signal can be verified against a known reference before the bypass is removed and the channel is returned to trip-capable status.

For sites where continuous operation is required, a temporary portable vibration analyser connected to the Proximitor output can provide real-time signal validation while the permanent rack channel is being reconfigured. This approach allows the maintenance team to confirm probe functionality without relying solely on the rack’s built-in OK relay. Once the channel is verified and the rack is returned to normal operation, the System 1 trend data should be reviewed to confirm that the new probe’s baseline vibration signature is consistent with the historical data for that machine bearing location.

All replacement probes supplied by KNMKS are function-tested prior to shipment. Each unit is verified for gap sensitivity, output linearity, and connector integrity. In-stock units are available for same-week dispatch to minimise lead time on urgent maintenance requirements.

Retrofit Support FAQ

Q: Is the 330101-00-13-15-02-CN a direct replacement for the original Bently Nevada part?
A: Yes. The 330101-00-13-15-02-CN is a direct form-fit-function replacement for the original Bently Nevada specification. It is compatible with the 3300 XL Proximitor sensor and extension cable assemblies without modification to the existing installation.

Q: What commissioning steps are required after installing the replacement probe?
A: After physical installation, set the probe gap to achieve −10 VDC at the Proximitor output, verify the OK relay status on the rack channel, confirm the vibration reading is within the expected baseline range for the machine, and remove any bypass before returning the channel to trip-capable status. Update the System 1 or DCS tag documentation to reflect the replacement date.

Q: Can this probe be used with a Bently Nevada 3500 Series rack?
A: Yes, when paired with a compatible 330180 Proximitor and the appropriate extension cable, the 330101-00-13-15-02-CN can be used with 3500/42M and 3500/45 monitor modules. Confirm the Proximitor model and sensitivity factor match the 3500 channel configuration before installation.

Q: What support terms and supply terms does KNMKS offer?
A: All units carry a support terms confirmed by quotation from the date of shipment. KNMKS maintains in-stock inventory for immediate dispatch. For volume requirements or long-term supply agreements, contact the sales team directly to discuss lead times and pricing.
