Bently Nevada 330101-39-67-10-12-05 Proximity Probe

330101-39-67-10-12-05 — Every Hour of Downtime Costs You. We Ship Today.

Your turbine tripped at 02:00. The DCS is throwing Probe Not OK faults. Maintenance has pulled the proximity probe and confirmed it’s dead — cable shorted, tip cracked, or the oscillator is reading rail voltage. You need a verified Bently Nevada 330101-39-67-10-12-05 in your hands before the next shift, not in three weeks. That’s exactly what we stock for.

We maintain physical inventory of the 3300 XL 8mm proximity probe series in Xiamen, China. No broker delays, no cross-docking. Your order is inspected, packed, and handed to DHL or FedEx the same business day. Whether you’re in Rotterdam, Houston, or Jubail — we’ve done it before.

Quick Technical Datasheet

Troubleshooting & Replacement Tips

Common fault codes that lead you here:

• 3500 Monitor: CH FAULT / NOT OK — Gap voltage out of range. First check: measure DC output at the driver BNC. If reading –2 VDC or less (rail low), probe tip is too close or shorted. If reading –22 VDC or above (rail high), probe is too far, cable is open, or probe is failed.
• DCS Alarm: Vibration High-High / Danger — Before condemning the probe, verify the gap. A probe that has backed out 0.5 mm due to vibration-induced thread loosening will throw spurious danger alarms. Check the reverse-mount locknut torque (typically 2.8 N·m).
• Intermittent Signal / Noise Floor Spike — 90% of the time this is the extension cable, not the probe. Flex the armored cable near the connector while watching the driver output. Any signal jump = cable failure. The 330101 probe itself rarely fails intermittently.

Step-by-step hot-swap procedure (planned outage):

1. De-energize the 3500 rack channel or inhibit the trip logic before disconnecting — do not pull a live probe on a running machine.
2. Record the existing gap voltage from the driver BNC (target: –10.4 VDC ± 0.5 V at 1.0 mm nominal gap).
3. Disconnect the extension cable from the driver. Remove the probe from the bracket using a calibrated gap tool — count the turns so you can replicate the gap on the new unit.
4. Install the 330101-39-67-10-12-05 replacement. Thread in by hand until snug, then back out to match the original turn count. Verify gap voltage at the driver BNC before tightening the locknut.
5. Fine-adjust gap to achieve –10.4 VDC ± 0.2 V. Torque the reverse-mount locknut. Re-energize the channel and confirm OK status on the 3500 monitor.
6. Log the new gap voltage and date in your machinery history file. Done.

Configuration notes for the -05 suffix: The last two digits encode system cable length. This unit ships with a 5-meter system cable. If your driver is mounted more than 5 meters from the junction box, you need the -08 (8 m) or -15 (15 m) variant. Mismatched cable length shifts the oscillator frequency and invalidates the calibration curve — this is a common field error that produces a 3–8% scale factor deviation.

Firmware / driver matching: The 330101 probe is passive — it has no firmware. However, the paired 330180 driver must be configured for the 8mm probe type. Verify the driver’s internal DIP switch S1 is set to position 2 (8mm). Incorrect switch position causes a 25% sensitivity error that will not trigger a fault but will produce incorrect vibration readings.

Reliability in Harsh Conditions

The 3300 XL 8mm probe was not designed for a clean lab. It was designed for the inside of a compressor train running at 12,000 RPM in a 55°C ambient with lube oil mist, high-frequency acoustic excitation, and 24/7 uptime requirements. Here’s what it handles without complaint:

• Vibration: The probe body is rated to 20 g continuous sinusoidal vibration across 10–2000 Hz. The reverse-mount 10-32 UNF thread is specifically engineered to resist self-loosening under axial vibration — a failure mode that plagues standard right-hand thread probes in high-speed machinery.
• Temperature: Rated to +177°C at the probe tip. In practice, bearing housing installations on steam turbines routinely see 120–150°C. The probe operates without drift across this range. The armored extension cable uses PTFE insulation rated to the same temperature class.
• Moisture & Contamination: IP67 rating means the probe tip and body survive full immersion to 1 meter for 30 minutes. In practice, this translates to resistance against high-pressure wash-down, condensation in cold-start conditions, and lube oil ingress at the probe tip. The connector end requires a properly seated cable — do not leave the BNC connector exposed in wet environments.
• EMI: The eddy current sensing principle is inherently immune to electrostatic interference. The armored cable provides a Faraday shield against radiated EMI from VFDs, switchgear, and welding equipment operating in the same area. Ground the armor at one end only (driver end) to prevent ground loop noise.
• Chemical Resistance: The probe housing is 316 stainless steel. The cable jacket is rated for exposure to petroleum-based lubricants, glycol coolants, and mild cleaning solvents. Avoid prolonged contact with strong acids or chlorinated solvents.

Global Express Logistics

Our warehouse is located in Xiamen, Fujian Province — one of China’s primary export hubs with direct access to Xiamen Gaoqi International Airport (XMN) and Xiamen Port. This matters when you’re counting hours, not days.

• Order cutoff: Orders confirmed and paid before 14:00 CST ship the same business day. Orders after cutoff ship the following morning.
• DHL Express: Xiamen → Europe (Rotterdam, Frankfurt, Amsterdam): 2–3 business days. Xiamen → Middle East (Dubai, Jubail, Dammam): 3–4 business days. Xiamen → North America (Houston, Los Angeles): 3–5 business days.
• FedEx International Priority: Available as an alternative carrier for destinations where DHL has service disruptions. Transit times are comparable. We select the faster option at time of booking.
• Documentation: Commercial invoice, packing list, and certificate of origin issued with every shipment. For customers requiring a Certificate of Conformance or material test report, request at time of order — we prepare these before dispatch, not after.
• Customs classification: HS Code 9031.80 (measuring/checking instruments). We declare accurate values — no under-declaration. This protects your import clearance and avoids customs holds that cost you more time than the duty savings.
• Tracking: AWB number sent via email within 2 hours of dispatch. Real-time tracking link provided. For urgent shipments, our logistics team monitors the shipment and proactively contacts you if any customs delay is detected.
