Bently Nevada 330104-00-17-10-01-CN Retrofit-Ready 5mm Proximity Transducer for 3300 XL Control Systems
The Bently Nevada 330104-00-17-10-01-CN is a 5mm proximity transducer designed for the 3300 XL series vibration monitoring platform. For maintenance engineers managing aging machinery protection systems, this unit provides a direct retrofit path for legacy installations where the original transducer has reached end-of-life or where the OEM no longer supports the original part number. With full compatibility across the 3300 XL signal conditioning chain, this transducer enables smooth system restoration without requiring reprogramming of the monitoring rack or reconfiguration of the connected Bently Nevada 3300/16 or 3300/20 monitor cards.
Industrial facilities running continuous rotating equipment — including turbines, compressors, pumps, and fans — depend on proximity transducers for real-time radial vibration and position measurement. When a transducer fails or degrades, the entire protection loop is compromised. The 330104-00-17-10-01-CN allows procurement and maintenance teams to restore full monitoring capability quickly, with a tested and verified unit that meets the original electrical specification of the 3300 XL transducer family.

Retrofit Planning for Existing Automation Systems
A successful retrofit of the 330104-00-17-10-01-CN into an existing 3300 XL system requires a structured review of the surrounding signal chain. Maintenance engineers should begin by confirming the power supply feeding the Proximitor — typically the Bently Nevada 3300/05 Power Supply module — is delivering a stable -24 VDC rail. Voltage fluctuations at the Proximitor input will directly affect transducer output linearity and can cause false alarms or missed trips in the protection system.
Next, inspect the 330130 series extension cable connecting the transducer to the Proximitor. Cable damage, connector corrosion, or impedance mismatch are common causes of signal degradation in long-running installations. If the extension cable is original to the system, replacement alongside the transducer is strongly recommended to avoid reintroducing the fault after the new unit is installed.
The 330180 Proximitor Sensor should also be evaluated. In systems where the transducer has failed due to environmental stress — high temperature, contamination, or mechanical shock — the Proximitor may have sustained secondary damage. Confirm the Proximitor output voltage is within specification before closing the loop. For systems using the 3300/16 or 3300/20 monitor cards, verify that the channel configuration in the rack has not drifted and that the OK relay output is functioning correctly.
At the rack level, check the 3300 XL monitor card’s terminal block wiring for continuity and correct polarity. Loose or corroded terminals on the I/O side are a frequent source of intermittent faults that are misdiagnosed as transducer failure. If the facility uses a DCS or safety system interface — such as a Honeywell TDC 3000 or Emerson Ovation integration — confirm that the 4–20 mA or relay output from the monitor card is still correctly mapped to the control system’s input module.
For facilities with older Bently Nevada 3500 series racks running alongside 3300 XL systems, note that the 3500/42M Proximitor I/O module uses a different wiring scheme and is not directly interchangeable. Ensure the correct transducer family is matched to the rack before installation. Similarly, if the site is migrating from a 3300 XL to a 3500 series platform as part of a broader modernization project, the 330104-00-17-10-01-CN can serve as an interim solution to maintain protection continuity during the transition period.
Downtime Control During System Migration
Minimizing unplanned downtime during a proximity transducer replacement requires preparation before the machine is taken offline. Maintenance teams should pre-stage the 330104-00-17-10-01-CN, the replacement extension cable, and any required tooling — including a calibrated gap-setting tool and a digital voltmeter — before the maintenance window begins. Having the Proximitor output voltage specification and the monitor card’s OK threshold values documented in advance eliminates delays during commissioning.
Where the process allows, a hot-standby or redundant monitoring channel should be activated before the faulty transducer is removed. This preserves the protection function during the swap and allows the new transducer to be verified against the live channel before the redundant path is restored. For single-channel installations, coordinate with the control room to place the affected monitor card in bypass mode and confirm that the safety interlock logic is acknowledged before proceeding.
After installation, perform a static gap check by measuring the Proximitor output voltage with the shaft stationary. The target is -10.0 VDC ±0.5 V at the nominal gap distance. Once the machine is restarted, confirm that the vibration reading on the 3300 XL monitor card is stable and within the expected baseline range. Document the as-found and as-left gap voltages in the maintenance record to support future trend analysis and predictive maintenance planning.

A: Yes. The 330104-00-17-10-01-CN is compatible with other 5mm variants in the 330104 family. Minor suffix differences typically relate to cable length or connector options. Confirm the cable length and connector type match your installation before ordering. Our technical team can assist with cross-reference verification.
Q: What testing is performed before shipment?
A: Each unit undergoes electrical continuity testing, output voltage verification at nominal gap, and visual inspection before dispatch. A test report is available upon request. All units are covered by a 12-month warranty from the date of shipment.
