Bently Nevada 330101-00-67-20-02-CN Proximity Probe

330101-00-67-20-02-CN — Stop the Clock on Your Downtime. Ship Today.

Every minute a turbine or compressor sits idle costs real money — in lost throughput, penalty clauses, and emergency labor. The Bently Nevada 330101-00-67-20-02-CN 8 mm eddy-current proximity probe is one of the most field-replaced components in the 3300 XL Proximitor system, and when it fails, you need a verified unit on a plane — not a two-week lead time from a regional distributor. We stock it. We ship it today from Xiamen.

This is not a refurbished unit. Not a grey-market pull. Every probe leaving our warehouse is a 100% original Bently Nevada 3300 XL Series component, inspected against OEM dimensional and electrical specifications before it is boxed. If your machinery protection system is throwing a Not OK or your DCS is logging a gap voltage out of range, this is the part that gets you back online.

Troubleshooting & Replacement Tips

The 330101-00-67-20-02-CN fails in predictable ways. Here is what you will see in the field and how to deal with it fast:

Fault 1 — Gap Voltage Out of Range (typical: −10.5 V to −18 V window)
If your Proximitor monitor is flagging a Not OK and gap voltage is reading above −10 V or below −19 V, the probe tip is either physically damaged, the target gap has shifted, or the probe coil has shorted. First, verify the air gap at the probe tip — nominal is 1.0 mm (40 mil) for this 8 mm probe. If gap is correct and voltage is still off, swap the probe. Do not attempt to re-gap a shorted coil.

Fault 2 — Intermittent Signal / High Noise Floor
Caused 80% of the time by a compromised coaxial connector or a micro-fracture in the integral cable near the probe body — common in installations with high vibration or repeated thermal cycling. Flex the cable near the probe body while watching the gap voltage on your monitor. If voltage fluctuates, the cable is the culprit. Replace the full probe assembly; do not splice the integral cable.

Fault 3 — Sensitivity Drift
If your vibration readings are trending low or the system is failing calibration checks, sensitivity may have drifted from the nominal 7.87 V/mm. This is typically caused by probe tip contamination (oil, metallic debris) or coil degradation from sustained high-temperature exposure. Clean the tip with isopropyl alcohol first. If sensitivity is still outside ±1% of nominal after cleaning, replace the probe.

Replacement Procedure — Key Steps:

• Power down the Proximitor driver before disconnecting the probe. Do not hot-swap.
• Record the existing gap voltage before removal — this is your baseline for the new probe setup.
• Thread the new 330101-00-67-20-02-CN into the probe mount. Torque to OEM spec (do not over-torque — the probe body is stainless but the threads are fine-pitch).
• Set air gap to 1.0 mm (40 mil) using a non-ferrous feeler gauge. Confirm gap voltage reads −12.0 V ± 0.5 V at nominal gap.
• Verify the extension cable (330130-045-00-CN) and driver (330180-X1-05) are from the same matched system set. Mixing cable lengths from different system configurations will shift the calibration curve.
• Run a full system check on the 3500 monitor before returning the machine to service.

Reliability in Harsh Conditions

The 3300 XL probe series was not designed for a clean lab environment. It was built for the inside of a gas turbine enclosure, a petrochemical compressor train, and a paper mill where ambient temperature swings 60 °C between seasons and the floor vibrates at 1g continuously.

The 330101-00-67-20-02-CN probe body is constructed from 316 stainless steel with a PEEK (polyether ether ketone) tip housing — chemically resistant to most process fluids including lube oil, seal gas, and mild acids. The integral cable uses a fluoropolymer jacket rated to +177 °C continuous, with a braided shield that maintains signal integrity in environments with high electromagnetic interference from VFDs and large motor starters.

Vibration resistance is validated to IEC 60068-2-6 (sinusoidal) and IEC 60068-2-64 (random). In practice, this means the probe survives the resonance frequencies that destroy cheaper sensors — particularly the 50–200 Hz range where compressor blade-pass frequencies concentrate. The coaxial CN connector is rated for 500+ mating cycles and maintains contact resistance below 10 mΩ throughout its service life.

Units in our Xiamen stock are stored in climate-controlled conditions (18–25 °C, RH < 60%) in original OEM anti-static packaging. No shelf degradation. No moisture ingress. What you receive is functionally equivalent to a unit pulled from a factory-sealed carton.

Global Express Logistics

Our dispatch hub is in Xiamen, Fujian — one of China’s primary export ports with direct DHL and FedEx gateway access. Here is how a typical urgent order moves:

• Order confirmed before 14:00 CST: Same-day dispatch. DHL Express or FedEx International Priority label generated within 2 hours of payment confirmation.
