Bently Nevada 330173-00-06-10-02-CN Proximity Transducer

330173-00-06-10-02-CN: Stop the Clock on Your Downtime — Ship Today from Xiamen

Every hour a turbine, compressor, or pump sits idle because of a failed proximity transducer costs real money — production losses, penalty clauses, emergency labor. The Bently Nevada 330173-00-06-10-02-CN is on the shelf right now. We cut the lead time from weeks to days. Place your order before 14:00 CST and it moves the same business day via DHL Express or FedEx International Priority. No waiting on factory allocation. No distributor back-order queue.

This is a genuine OEM Bently Nevada 3300 XL Series 5 mm eddy current proximity transducer system — not a compatible, not a clone. It drops straight into your existing 3300 XL rack installation without recalibration of the monitoring system, provided the matched driver and extension cable are retained. If you are replacing a failed probe mid-campaign, that matters enormously.

Troubleshooting & Replacement Tips

Most common failure modes for the 330173 series:

• Gap voltage out of range (not –10 V ±0.5 V at nominal gap): Before condemning the probe, check the driver first. A shorted extension cable or corroded connector at the driver input will produce the same symptom. Disconnect the probe at the junction box and measure driver output with a known-good 50 Ω termination. If output recovers, the cable or probe is the fault — not the driver.
• 3500 rack alarm: OK relay de-energized, channel fault LED lit: This almost always means the transducer system is outside its linear range or the driver is not receiving supply voltage. Verify –24 VDC at the driver terminal before pulling the probe. A blown fuse on the I/O module power rail is a common culprit that gets overlooked.
• Intermittent vibration spikes with no process change: Inspect the armored cable along its full run. Fatigue cracking at the conduit entry point — especially on reciprocating compressors — causes intermittent open circuits that look like real vibration events. Flex the cable while watching the gap voltage on a DMM. Any flicker confirms cable failure.
• Probe reads correctly on bench but fails in situ: Target material mismatch. The 330173 is calibrated for AISI 4140 steel. If your shaft is 17-4 PH stainless, Inconel, or titanium, the scale factor shifts significantly. Bently Nevada publishes material correction factors — apply them or order a factory-calibrated system for your specific target alloy.

Replacement procedure — critical configuration checks:

• Matched system integrity: The 3300 XL is a three-component matched system: probe (330173) + extension cable (330130 series) + driver (330180 series). Replacing only the probe while retaining an old or mismatched driver invalidates the scale factor. Always verify the driver part number matches the probe diameter (5 mm = 330180-91-00).
• Gap setting: Install the probe to achieve a gap voltage of –10.0 VDC ±0.2 V at the driver output, corresponding to approximately 1.27 mm (50 mil) physical gap. Use a calibrated gap tool or feeler gauge. Do not rely on thread count alone — probe body tolerances vary.
• Cable routing: Maintain minimum bend radius of 50 mm on the integral armored cable. Tight bends at conduit entries are the number-one cause of premature cable failure in the field. Use a strain relief fitting at every conduit entry point.
• Connector seating: The CN connector must be fully seated and the locking collar torqued to 1.1 N·m (10 in-lb). Under-torqued connectors on vibrating machinery back out within weeks and produce the same symptom as a failed probe.
• 3500 rack channel configuration: After probe swap, navigate to the 3500 rack configuration software and verify the transducer type is set to 3300 XL 5 mm, scale factor 200 mV/mil. If a previous technician manually overrode the scale factor, the rack will accept the new probe but report incorrect engineering units.

Reliability in Harsh Conditions

The 330173-00-06-10-02-CN was not designed for a clean lab. It was designed for the bearing pedestals of 50 MW steam turbines, the gearbox housings of offshore compressor trains, and the pump decks of petrochemical facilities where ambient temperatures swing 80 °C between winter shutdowns and summer peak load.

The probe body is constructed from 316 stainless steel with a PEEK-encapsulated coil assembly. The armored integral cable uses a stainless braid over a fluoropolymer jacket — resistant to hydrocarbon condensate, steam, and the cleaning solvents routinely used during outage maintenance. The CN connector employs gold-plated contacts with a positive-locking collar that maintains contact integrity under continuous vibration loads up to 20 g.

Operating temperature ceiling of +121 °C at the probe tip covers the vast majority of bearing housing installations, including high-pressure steam turbine applications where bearing metal temperatures routinely exceed 90 °C. The driver, rated to +66 °C, should be located in a ventilated junction box away from direct radiant heat sources — a standard installation practice that is frequently ignored and is the leading cause of premature driver failure in hot environments.

Ingress protection is achieved through the sealed probe body and the armored cable assembly. While Bently Nevada does not publish an IP rating for this assembly, field experience across thousands of installations confirms reliable operation in wash-down environments and in installations where condensation is a persistent issue. The critical vulnerability is the connector interface — keep it clean, keep it torqued, and apply a thin film of dielectric grease if the installation is in a high-humidity or salt-laden atmosphere.
