Bently Nevada 330102-00-16-10-02-00 – 8mm Eddy Current Proximity Probe | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting eddy current measurement systems, widely deployed in critical rotating machinery protection and condition monitoring applications. The 330102-00-16-10-02-00 is an 8mm proximity probe engineered for high-resolution shaft radial vibration, axial position, and differential expansion measurement in turbomachinery and industrial rotating equipment.
Product Positioning
Designed for procurement engineers specifying vibration monitoring instrumentation in power generation, oil & gas, petrochemical, and heavy industrial environments. This probe integrates directly with Bently Nevada 3300 XL proximitor/seismic monitors and is fully compatible with System 1 condition monitoring software. It is the preferred replacement and upgrade path for legacy 3300 series installations.

- High frequency response — captures sub-synchronous, synchronous, and super-synchronous vibration components
- Direct system integration — plug-and-play with 3300 XL proximitor monitors (3300/16, 3300/20, 3300/55)
- API 670 compliant — meets machinery protection standard for critical service applications
- Rugged IP67 construction — resistant to oil mist, coolant splash, and industrial contaminants
System Architecture & Signal Flow
The 330102-00-16-10-02-00 probe forms the sensing element of a three-component measurement chain:
- Proximity Probe (330102-00-16-10-02-00) — generates eddy current field; outputs raw impedance change as voltage signal via coaxial cable
- Extension Cable (330130 series) — transmits signal from probe to proximitor; total system cable length must equal 5.0 m, 9.0 m, or 15.0 m for factory calibration accuracy
- Proximitor / Monitor (3300 XL series) — conditions signal, provides –24 VDC excitation, outputs 4–20 mA or voltage to DCS/PLC/safety system
Note: Probe, extension cable, and proximitor must be ordered as a matched set calibrated to the same total cable length for specification-grade accuracy.
Sourcing & Quality Verification
- All units sourced through verified industrial automation supply channels with full traceability
- Each assembly inspected for connector integrity, cable continuity, and jacket condition prior to dispatch
- Original manufacturer documentation and calibration certificates available upon request
- Serialization and date codes verified against Bently Nevada production records where applicable
- Konmask.com maintains a no-counterfeit policy — all products are subject to incoming quality inspection
Procurement Process
- Confirm part number — verify suffix codes match your cable length, armoring, and connector requirements
- Specify target material — standard calibration is AISI 4140; non-standard targets require recalibration
- Confirm total system cable length — probe + extension cable must equal factory-calibrated length
- Submit RFQ or place order — contact support@konmask.com with quantity, delivery location, and required lead time
- Receive with documentation — shipping includes packing list, inspection record, and available OEM documentation
Technical FAQ
Q: Can this probe be used with legacy Bently Nevada 3300 (non-XL) monitors?
A: The 3300 XL probe series is backward-compatible with most 3300 series monitors. Verify monitor input impedance and supply voltage specifications before substitution.
Q: What is the maximum shaft surface speed for reliable measurement?
A: Eddy current probes have no mechanical speed limitation. Electrical frequency response (DC–10 kHz) is the practical upper bound, supporting shaft speeds well above 600,000 RPM for 8mm probes.
Q: Is recalibration required after installation?
A: Factory calibration is valid for the specified probe + cable length combination. Field gap setting (typically 1.0–1.5 mm) is required during commissioning using a calibrated gap tool or oscilloscope.
Q: What is the lead time for this part number?
A: Standard lead time is 3–7 business days for in-stock units. Contact us for urgent requirements or volume orders.
Q: Do you provide ATEX/IECEx documentation for hazardous area installations?
A: Yes. ATEX certification documentation is available upon request. Please specify the hazardous area zone classification when ordering.
