Bently Nevada 330103-00-05-50-02-05 – 8mm Eddy Current Proximity Probe | 3300 XL Series
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contact shaft vibration and position measurement in rotating machinery. Engineered to API 670 standards, the 3300 XL proximity probe system is the preferred solution for turbines, compressors, pumps, and motors in critical process industries worldwide. The 330103-00-05-50-02-05 is the 8mm diameter variant configured with a 5-metre armored extension cable and standard -24 VDC bias voltage output, making it directly compatible with the full 3300 XL signal conditioning ecosystem.
Product Positioning
This probe is designed for procurement engineers and reliability teams sourcing OEM-equivalent replacement parts for existing Bently Nevada monitoring systems. It integrates without recalibration into any 3300 XL driver/monitor chain and is stocked by Konmask.com for immediate global dispatch.

- Wide frequency bandwidth – captures DC shaft position through high-frequency vibration events up to 10 kHz
- Armored cable construction – resists oil, steam, and chemical exposure in harsh plant environments
- Direct API 670 compliance – meets machinery protection system requirements without additional certification
- Plug-and-play replacement – identical form, fit, and function to OEM; no monitor reconfiguration required
- Stable scale factor – 200 mV/mil output consistent across the full operating temperature range
System Architecture & Signal Flow
The 330103-00-05-50-02-05 probe operates as the sensing element in a three-component Bently Nevada 3300 XL measurement chain:
- Probe (330103 series) – generates eddy current field; outputs raw impedance change as voltage signal via armored cable
- Extension Cable (330130 series) – transmits signal from probe to driver; total system cable length must match driver calibration (typically 5 m + 5 m = 10 m total)
- Driver / Proximitor (330180 series) – conditions signal, provides -24 VDC excitation, outputs calibrated voltage to monitor
- Monitor (3300 series rack) – processes voltage, applies alarm/trip setpoints, communicates to DCS/PLC via 4–20 mA or digital protocols
Note: Total cable length (probe cable + extension cable) must equal the driver’s calibrated length. Verify driver part number before ordering.
Sourcing & Quality Verification
- All units sourced from authorized distribution channels or verified surplus with full traceability documentation

Technical FAQ
Q: Can this probe be used with a 330180-X1-05 driver configured for 10 m total cable?
A: No. The 330103-00-05-50-02-05 has a 5 m probe cable. Pair it with a 5 m extension cable (330130-080-00-05) to reach the 10 m total required by that driver.
Q: Is recalibration required when replacing an existing 330103 probe?
A: Not if the replacement probe is the same part number and the target material is unchanged. The 200 mV/mil scale factor is factory-set and consistent across production lots.
Q: What target materials are supported without recalibration?
A: AISI 4140 steel is the standard calibration target. Other ferromagnetic alloys may require a field calibration check. Non-ferrous targets (aluminum, titanium) require a special-order calibrated system.
Q: Does Konmask provide expedited shipping for plant shutdowns?
A: Yes. Contact us directly at +0086 19859288691 for emergency procurement support. We maintain stock for same-day dispatch on most 3300 XL components.
Q: What is the HS code for customs clearance?
A: 9031.80 – Measuring or checking instruments, appliances and machines, not elsewhere specified.
