Bently Nevada 330104-00-02-05-02-00 Proximity Transducer

330104-00-02-05-02-00 In Stock — Every Hour of Downtime Costs You More Than This Module

Your turbine tripped at 02:00. The vibration monitor is throwing a Not OK on channel 1. Maintenance has isolated the fault to the proximity transducer loop — and the probe is dead. You need a Bently Nevada 330104-00-02-05-02-00 on-site before the next shift handover, or production stays flat. We stock it. We ship it today.

The 330104-00-02-05-02-00 is a 5 mm eddy-current proximity probe from Bently Nevada’s 3300 XL Series — the global benchmark for non-contact shaft vibration and axial position measurement on critical rotating machinery. This is not a substitute, not a compatible alternative. It is the exact OEM part number your 3500 rack is expecting.

Troubleshooting & Replacement Tips

Fault Scenario 1 — Monitor shows Not OK / gap voltage out of range
The 3300 XL driver outputs a DC gap voltage proportional to probe-to-target distance. Nominal gap for a 5 mm probe on a 4140 steel shaft is typically 1.0 mm (–10.5 VDC ±0.5 V). If you are reading outside –7 V to –18 V at the driver output, the probe or extension cable is suspect before you condemn the monitor card.

Step-by-step swap procedure:

• Step 1 — Isolate the loop. Disconnect the driver from the 3500 monitor I/O module. Confirm the monitor channel goes to Not OK — this rules out a monitor card fault.
• Step 2 — Bench-test the driver. Apply –24 VDC to the driver. Use a steel target at 1.0 mm gap. Verify output is –10.5 VDC ±0.5 V. If the driver passes, the probe or cable is the fault.
• Step 3 — Inspect the extension cable. The 330130 series extension cable is a common failure point in high-vibration installations. Check for chafing at conduit entry points and connector corrosion at both ends.
• Step 4 — Replace the probe. Install the new 330104-00-02-05-02-00. Set the gap to 1.0 mm using a feeler gauge. Verify gap voltage at the driver output before reconnecting to the monitor.
• Step 5 — Re-zero the monitor channel. On the 3500/40M, navigate to the channel configuration and perform a gap re-zero if the new probe gap differs from the previous installation by more than 0.1 mm. Failure to re-zero will cause a false radial vibration offset reading.
• Step 6 — Confirm OK status. With the machine at rest, the monitor channel should return to OK with vibration reading near 0 µm pk-pk. Any residual reading above 25 µm at rest indicates a grounding or cable shield issue — check shield continuity end-to-end.

Fault Scenario 2 — Intermittent Not OK during machine run-up
This is almost always a loose connector at the probe-to-extension cable junction. The 3300 XL uses a threaded BNC-style connector. Vibration at critical speed can cause micro-arcing at a partially seated connector, producing a momentary open circuit that the monitor interprets as a gap fault. Torque the connector to finger-tight plus a quarter turn. Apply thread-locking compound if the environment exceeds 50 g vibration.

Fault Scenario 3 — Probe reads correctly at rest but drifts during thermal soak
The 330104 probe tip is rated to +177 °C, but the integral cable jacket begins to degrade above 150 °C with sustained exposure. If the probe is routed through a hot zone, verify the cable routing clears heat shields by at least 50 mm. Thermal drift exceeding 0.5 V over a 100 °C temperature rise indicates cable insulation breakdown — replace the probe and re-route.

Configuration note — 3300 XL driver address switches:
The 330180 series driver does not use DIP address switches. It is a passive analog device. No firmware, no addressing. The only configuration is the gap adjustment screw on the driver housing, which sets the output offset. Do not confuse this with the 3500 monitor rack slot addressing — that is handled in the 3500 System Monitor software, not at the transducer level.

Reliability in Harsh Conditions

The 3300 XL Series was not designed for a clean lab. It was designed for the bearing pedestal of a 50 MW steam turbine running 24/7 in a coastal petrochemical plant. The 330104-00-02-05-02-00 reflects that design philosophy at every level.

The probe body is machined from 316 stainless steel, providing corrosion resistance in humid, salt-laden, and H₂S-bearing atmospheres. The integral coaxial cable uses a PTFE-insulated center conductor with a braided stainless steel outer shield — this combination maintains signal integrity in environments where standard PVC-jacketed cables fail within months. The probe tip assembly is epoxy-potted to prevent moisture ingress, and the connector interface is sealed to IP67 when mated.

Vibration endurance: the 330104 probe assembly is qualified to 20 g continuous sinusoidal vibration across 10–2,000 Hz per IEC 60068-2-6. In practice, field installations on reciprocating compressors routinely exceed this without failure. The threaded mounting body allows torque-controlled installation to prevent loosening under cyclic loading.

Thermal cycling: the probe has been validated through 1,000 thermal cycles between –35 °C and +150 °C without measurable change in scale factor. This matters in outdoor installations where ambient temperature swings 60 °C between summer day and winter night — your calibration stays valid year-round.

EMI immunity: the coaxial construction provides inherent common-mode rejection. In VFD-heavy environments where switching frequencies generate broadband electrical noise, the 3300 XL probe loop maintains signal-to-noise ratios sufficient for reliable 1× and 2× vibration component extraction at speeds from 300 RPM to 60,000 RPM.
