Bently Nevada 330101-00-15-10-01-00 Proximity Probe

330101-00-15-10-01-00 In Stock — Every Hour of Downtime Costs You More Than This Part

Your turbine tripped at 02:00. The DCS is screaming Probe Fault – Channel 1. Maintenance has already pulled the housing and confirmed the 8 mm eddy-current probe is dead — cable shorted, tip corroded, signal rail pegged at −24 V. You need a Bently Nevada 330101-00-15-10-01-00 on-site before the next shift handover, not in three weeks. We stock it. We ship it today.

At siemensplc.com, we maintain physical inventory of the 3300 XL probe family specifically because turbomachinery protection failures don’t follow procurement calendars. One confirmed order before 15:00 CST gets your unit into a DHL Express or FedEx International Priority consignment the same afternoon, tracked door-to-door from Xiamen to your plant gate.

Troubleshooting & Replacement Tips

After ten years of field calls on rotating machinery, these are the failure modes and swap pitfalls that actually bite engineers on the 330101-00-15-10-01-00:

Fault Code: OK Relay De-energized / Probe Fault Alarm
Nine times out of ten this is a gap voltage outside the −10 V ± 1 V target. Before condemning the probe, measure DC output at the Proximitor driver BNC. If you read −24 V (rail), the probe cable is open — check the 10-32 connector first; the center pin backs out under vibration. If you read 0 V, the driver supply is missing. Only if gap voltage is correct and the monitor still alarms is the probe itself suspect.

Air Gap Setting — Get This Right Before You Torque the Jam Nut
The 330101-00-15-10-01-00 linear range is 0.25 – 2.54 mm. Target gap for most journal bearing applications is 1.0 – 1.5 mm, corresponding to −10 V ± 1.5 V at the driver output. Use a non-ferrous feeler gauge or a calibrated gap tool. Set gap cold — thermal growth will close it 0.1 – 0.3 mm at operating temperature depending on your bearing housing material. Do not set gap with the shaft turning.

Extension Cable Matching
The 330101 probe is factory-calibrated as a system with a specific extension cable length. The total probe-plus-extension cable must equal the length the Proximitor driver was calibrated for — typically 5 m probe + 5 m extension = 10 m system, or 5 m probe + 9 m extension = 14 m system. Mixing cable lengths without recalibration shifts the sensitivity by up to 8% and will cause false vibration readings. Confirm the driver label for the system cable length before ordering extension cables.

Target Material Recalibration
Factory calibration assumes AISI 4140 steel. If your shaft is 17-4 PH stainless, Inconel, or titanium, sensitivity changes — sometimes dramatically. Run the Bently Nevada target material correction procedure or request a material-specific calibration certificate when ordering.

Connector Torque
The 10-32 coaxial connector must be finger-tight plus one-quarter turn with a 5/16-inch open-end wrench. Over-torquing cracks the PTFE dielectric; under-torquing causes intermittent contact that looks exactly like a failing probe on the trend display.

Replacement Steps (Offline, Shaft Stationary)

1. Inhibit the channel at the monitor to suppress spurious trips during swap.
2. Disconnect extension cable at the junction box — never pull from the probe end.
3. Back out the old probe using the M10 × 1 thread; note the number of turns for approximate gap reference.
4. Inspect the probe boss bore for debris, corrosion, or thread damage before installing the new unit.
5. Thread in the new 330101-00-15-10-01-00 to the approximate gap position; connect extension cable.
6. Power the Proximitor driver and measure gap voltage. Adjust probe depth until output is −10 V ± 0.5 V.
7. Lock jam nut to 14 N·m (10 ft·lb); re-verify gap voltage after torquing — it shifts slightly.
8. Remove channel inhibit, confirm OK relay energizes, and log the as-left gap voltage in your maintenance record.

Reliability in Harsh Conditions

The 3300 XL probe family was not designed for a climate-controlled instrument room — it was designed for the bearing pedestal of a 60 MW steam turbine running at 3,000 RPM in a coastal petrochemical complex. The 330101-00-15-10-01-00 reflects that design intent in every material choice.

The probe body is machined from 316 stainless steel, which resists chloride-induced pitting in marine and offshore environments where carbon steel housings corrode through in under two years. The integral cable jacket is rated to +177 °C continuous, covering the hot-section bearing environments found on gas turbine exhaust-end bearings where ambient temperatures routinely exceed 120 °C. The 10-32 coaxial connector uses a PTFE dielectric that maintains impedance stability across the full temperature range, preventing the sensitivity drift that plagues cheaper probe designs at elevated temperatures.

Vibration immunity is built into the integral cable construction. Unlike field-assembled probe-plus-extension systems with a junction at the probe body, the 330101 routes the signal conductor through a single continuous coaxial assembly from tip to connector. This eliminates the micro-motion fretting at splice points that generates noise indistinguishable from real shaft vibration on the monitor display — a failure mode that has caused unnecessary shutdowns on poorly maintained systems.

Ingress protection meets the requirements for outdoor and wash-down environments. The probe tip and cable entry are sealed against moisture intrusion, which matters in paper mills, water treatment plants, and any outdoor installation subject to rain or steam cleaning. Units stored in our Xiamen warehouse are kept in original OEM packaging with desiccant to preserve connector integrity until the moment of installation.
