Bently Nevada 330104-00-13-90-02-CN 3300 XL Transducer

Overview

Bently Nevada 330104-00-13-90-02-CN Migration-Ready 3300 XL Proximity Transducer for Legacy Control Systems

The Bently Nevada 330104-00-13-90-02-CN is an 8mm proximity transducer engineered for the 3300 XL series vibration monitoring platform. Designed as a migration-ready replacement for discontinued and end-of-life transducer assemblies, this unit supports direct drop-in substitution in existing machinery protection systems without requiring changes to the signal conditioning chain or monitor rack configuration. Whether you are managing a planned retrofit of an aging turbomachinery protection loop or responding to an unplanned failure of a legacy proximity probe, the 330104-00-13-90-02-CN delivers verified compatibility with the 3300 XL monitor series and the broader Bently Nevada ecosystem.

For plants operating legacy Bently Nevada 3300 series monitors, the transition to the 3300 XL platform represents one of the most common upgrade paths in rotating equipment protection. The 330104-00-13-90-02-CN is fully compatible with the 3300 XL 8mm Proximitor Sensor and integrates directly with the 3300/16 monitor, the 3300/20 dual-channel monitor, and the 3500/42M proximity monitor module. Engineers planning a rack-level upgrade should confirm that the existing Proximitor extension cable — typically the 330130 series — is retained or replaced with a matched-length assembly to preserve the calibrated gap voltage and sensitivity specification of −7.87 V/mm.

Retrofit Planning for Existing Automation Systems

A successful retrofit of the 330104-00-13-90-02-CN into an operating plant begins well before the maintenance window opens. The first step is a physical survey of the existing probe installation: confirm the available radial clearance around the shaft, verify the probe holder thread engagement, and measure the installed extension cable length. The 330130 extension cable must be ordered to match the exact field length — mismatched cable lengths alter the system capacitance and shift the calibrated output voltage, which will cause the 3300 XL or 3500/42M monitor to report a false gap alarm or an OK relay dropout.

On the monitor side, engineers should pull the channel configuration from the 3500 rack using the Bently Nevada 3500 Rack Configuration software before the outage begins. Confirm the full-scale range, the alert and danger setpoints, the transducer type selection, and the OK limit band. If the existing rack contains a 3300/16 monitor rather than a 3500-series module, note that the 3300/16 does not support Modbus communication natively; plants migrating to a System 1 condition monitoring platform will need to evaluate whether a 3500/42M module swap is part of the scope. In that case, the 3500 rack backplane and the 3500/20 rack interface module should be inspected for available slot positions before the outage is scheduled.

For plants that also operate Bently Nevada 3500/15 power supply modules, verify that the rack power budget accommodates the additional current draw if new monitor modules are being added alongside the transducer replacement. The 3500/15 supplies −24 VDC to the Proximitor sensors; adding channels without checking the power supply headroom is a common cause of post-retrofit instability. Similarly, if the control system integrates vibration data into a DCS or safety instrumented system via a 4–20 mA hardwired output, confirm that the analog output card at the receiving end — often a Rockwell Automation 1756-IF16 or a similar I/O module — is scaled to match the new transducer’s sensitivity and linear range before the loop is re-energized.

HMI screens that display shaft vibration trends should be reviewed and updated to reflect any tag renaming or channel reassignment that occurs during the retrofit. If the plant uses a Bently Nevada System 1 software platform for online machinery diagnostics, the asset hierarchy and transducer configuration database must be updated to reflect the new part number and calibration constants before the machine is returned to service. Failure to update the System 1 configuration will result in incorrect alarm thresholds and may mask developing faults during the post-retrofit monitoring period.

Downtime Control During System Migration

Minimizing unplanned downtime during a proximity transducer replacement requires a structured pre-outage preparation process. Before the machine is taken offline, the existing probe gap voltage should be recorded at the monitor front panel or via System 1 — this baseline reading serves as the acceptance criterion for the reinstalled 330104-00-13-90-02-CN after gap setting. All terminal wiring at the junction box and at the monitor card edge should be photographed and documented, with wire labels verified against the as-built loop drawing before any connections are disturbed.

During the replacement, the new probe should be installed and the gap set to the manufacturer-specified nominal value — typically 1.0 mm to 1.5 mm for most shaft applications — before the extension cable is connected to the Proximitor. The Proximitor output voltage should then be measured at the monitor input terminals with the machine stationary to confirm the gap is within the linear range. Only after this static verification should the monitor channel be re-enabled and the OK relay confirmed closed.

If the retrofit scope includes a simultaneous upgrade of the monitor module — for example, replacing a 3300/20 with a 3500/42M — the program logic in the associated safety or control system must be verified against the new monitor’s output signal format before the machine is restarted. Plants that have integrated vibration trip signals into a Rockwell Automation GuardLogix or a Siemens S7-300 safety PLC should perform a full functional test of the trip path, including a simulated high-vibration condition, before the machine is released to operations. This step is non-negotiable for API 670-compliant machinery protection systems and should be documented in the mechanical completion package.

All units supplied by KNMKS are pre-tested and verified against the original Bently Nevada specification prior to shipment. Each 330104-00-13-90-02-CN is shipped with a test report confirming sensitivity, linearity, and OK output function, reducing the time required for incoming inspection and accelerating the path to first-fire readiness.

Retrofit Support FAQ

Q: Is the 330104-00-13-90-02-CN a direct replacement for other 330104 suffix variants?
A: Yes. The 330104 series uses a common probe body with suffix codes that indicate cable length and connector configuration. The -00-13-90-02-CN suffix denotes a specific cable length and connector type. Provided the replacement unit shares the same Proximitor model and extension cable length, the substitution is direct and requires only a gap reset and sensitivity verification at commissioning. If the suffix differs, contact our technical team to confirm compatibility before ordering.

Q: What commissioning steps are required after installation?
A: After mechanical installation, set the probe gap to the specified nominal value and measure the Proximitor output voltage at the monitor input terminals. Confirm the OK relay is closed and the channel is within the configured OK band. Update the System 1 asset database with the new part number and calibration constants. Perform a static calibration check and record the as-left gap voltage in the maintenance management system before returning the machine to service.

Q: Can this transducer be used with a 3500/42M monitor without reconfiguring the rack?
A: In most cases, yes. The 3500/42M is configured via the Bently Nevada 3500 Rack Configuration software, and the transducer type selection must match the installed probe and Proximitor combination. If the existing rack was previously configured for a 3300 XL 8mm system, the channel configuration will typically transfer without modification. However, always verify the full-scale range, alert/danger setpoints, and OK limits in the rack configuration software before re-energizing the channel.

Q: What is the support terms and what does KNMKS stock availability look like?
A: All 330104-00-13-90-02-CN units supplied by KNMKS carry a support terms confirmed by quotation from the date of shipment, covering manufacturing defects and functional performance against the original Bently Nevada specification. We maintain in-stock inventory of this part number to support both planned maintenance outages and emergency breakdown situations. Orders confirmed before the daily cut-off are typically processed and shipped the same business day. Contact our sales team for current stock levels and lead time confirmation.
