Quick Technical Datasheet

Troubleshooting & Replacement Tips

Ten years of field calls on 3300 XL systems teach you the same lessons over and over. Here is what actually matters when you are standing in front of a hot machine with a replacement probe in your hand.

Fault Code 01 / OK LED Off — Probe Open Circuit
Ninety percent of the time this is cable damage at the probe-to-extension junction, not the probe body itself. Before condemning the 330103, disconnect the extension cable and measure resistance tip-to-connector: should read 7–9 Ω. If open, the probe winding is gone — replace the probe. If resistance is good, the fault is in the 330130 extension cable or the driver input card.

Fault Code 02 / Not OK — Gap Voltage Out of Range
This is the most common post-replacement call. The 330103-00-10-05-02-05 requires a gap voltage of −10.0 ± 0.5 VDC at the nominal 1.0 mm air gap on AISI 4140 steel. After seating the new probe, use a calibrated gap tool or feeler gauge. Do not trust the old probe’s gap setting — probe body tolerances vary by ±0.05 mm between units. Set gap fresh every time.

Non-Ferrous Target Warning
If your shaft is stainless steel (316L, 304) or titanium, the sensitivity drops significantly — you will read a false gap and the monitor will alarm or trip immediately. The 330103 is calibrated for AISI 4140. On non-standard target materials, request a special calibration certificate or use the Bently Nevada target material correction factor tables before commissioning.

Total Cable Length — Do Not Guess
The 3300 XL driver is tuned for a specific total cable capacitance. The 330103-00-10-05-02-05 carries a 5 m cable. If you add a 330130 extension, the combined length must match the driver’s configured system length (5 m or 9 m total). Mixing a 5 m probe with a 4 m extension on a driver configured for 5 m total will shift your sensitivity by 3–5% and cause intermittent Not OK faults under vibration.

Driver Firmware Compatibility
The 3300 XL driver (330180 series) does not require firmware changes for a like-for-like 330103 swap. However, if you are replacing a 330103 with a 330104 (11mm probe) as a temporary workaround, you must reconfigure the driver’s linear range and sensitivity parameters via the 3300 XL configuration software. Failure to do so will result in incorrect vibration readings and potential missed trips.

Connector Torque
The MIL-C-5015 connector on the 02-05 variant is a threaded coupling. Finger-tight is not enough in a high-vibration environment. Torque to 2.0–2.5 N·m and apply thread-locking compound (medium strength, e.g., Loctite 243) on the coupling ring. Vibration-induced connector loosening is responsible for more nuisance trips than actual probe failures.

Commissioning Checklist (Quick Reference)

• ☐ Verify driver configured for 5 m total cable system
• ☐ Set air gap to 1.0 mm on AISI 4140 target — confirm −10.0 VDC gap voltage
• ☐ Confirm target material; apply correction factor if non-ferrous
• ☐ Torque MIL-C-5015 connector to 2.0–2.5 N·m
• ☐ Check OK LED on driver — solid green before releasing machine
• ☐ Verify vibration reading at slow-roll (typically <0.5 mm/s) matches historical baseline
• ☐ Document new gap voltage in maintenance log

Reliability in Harsh Conditions

The 330103-00-10-05-02-05 was not designed for a clean lab. It was designed for the bearing pedestals of gas turbines running at 3,000 RPM in 45°C ambient, for compressor trains in offshore platforms where salt spray and condensation are daily realities, and for steel mill drives where floor vibration never stops.

The probe body is machined from 316 stainless steel with a PEEK tip insert — chemically resistant to lubricating oils, hydraulic fluids, and mild cleaning solvents. The cable jacket is rated to 177°C continuous, which covers hot-section installations where most competitive probes fail within 18 months. The MIL-C-5015 connector is IP67-rated when mated, preventing moisture ingress even in wash-down environments.

Vibration endurance: the 330103 is qualified to 20 g RMS broadband vibration per MIL-STD-810, which exceeds the API 670 requirement of 15 g. In practice, this means the probe survives the very machine vibration it is measuring — including the abnormal vibration events that trigger the trip it is supposed to detect.

Thermal cycling is where many third-party alternatives fail. The 330103’s cable assembly uses a fluoropolymer (FEP) inner insulation that maintains dielectric properties through repeated thermal cycles from cold startup (−35°C) to full operating temperature. Capacitance drift across this range is less than 2%, keeping your sensitivity calibration stable across seasons and operating cycles.

Every unit we ship has passed pre-dispatch electrical verification: tip resistance, cable insulation resistance (>100 MΩ at 500 VDC), and connector continuity. We do not ship untested stock.
