Compatible Replacement & Equivalent Models
When the original 3300/5/1 is unavailable or cost-prohibitive, the following models are commonly evaluated as replacements. Compatibility must be verified against your system configuration before substitution.
| Model | Brand | Tip Dia. | Cable | Compatibility Notes |
|---|---|---|---|---|
| 3300/5/1 | Bently Nevada (OEM) | 5 mm | 1 m | Original — direct fit |
| 3300/5/2 | Bently Nevada | 5 mm | 2 m | Longer cable variant; same probe head |
| 3300/8/1 | Bently Nevada | 8 mm | 1 m | Larger tip; different sensitivity — verify driver compatibility |
| PR6423/010-030 | Epro / GE | 8 mm | — | Cross-brand equivalent; requires compatible driver/conditioner |
| CWY-DO-810 | Shinkawa / Generic | 8 mm | — | Budget alternative; verify signal range and linearity |
Important: Probe, extension cable, and driver/conditioner must be purchased and calibrated as a matched set for accurate measurement.
Why Choose the Original Model
- Factory Calibration: The 3300/5/1 is factory-calibrated as part of a matched probe/cable/driver system, ensuring measurement accuracy within ±1%.
- System Certification: OEM parts maintain API 670 compliance and do not void existing system certifications.
- Long-term Support: Bently Nevada provides full technical support, firmware compatibility, and traceability documentation.
- Reliability: Proven in critical rotating machinery monitoring (turbines, compressors, pumps) in oil & gas, power generation, and petrochemical industries.
Typical Applications
- Radial shaft vibration monitoring on steam and gas turbines
- Axial position measurement on centrifugal compressors
- Differential expansion monitoring in power plant turbines
- Eccentricity and speed measurement on large rotating machinery
- Keyphasor® reference signal generation
System Compatibility
The 3300/5/1 probe is designed to operate within the Bently Nevada 3300 Series monitoring ecosystem. Ensure the following components are matched:
- Extension Cable: 3300 XL Series (e.g., 330130-045-00-CN)
- Driver/Conditioner: 3300 XL 8 mm Proximitor® or equivalent 3300-series driver
- Monitor: 3300/16 or 3500 Series rack-mounted monitors
- DCS/PLC Integration: 4–20 mA or voltage output compatible with Siemens, ABB, Emerson DeltaV, Honeywell systems
Selection Guide
Use the following criteria to select the correct probe for your application:
- Tip Diameter: 5 mm (3300/5/x) for tight clearance installations; 8 mm (3300/8/x) for standard installations with higher sensitivity.
- Cable Length: Select suffix /1 (1 m), /2 (2 m), /5 (5 m) based on distance from probe to junction box. Total system cable length (probe + extension) must match driver calibration range.
- Target Material: Standard probes calibrated for AISI 4140 steel. Non-standard targets (titanium, aluminum, Inconel) require recalibration or special-order probes.
- Environment: For high-temperature zones (>150°C), specify high-temperature probe variants. For hazardous areas, confirm ATEX/IECEx zone rating.
- Replacement vs. Upgrade: If upgrading from 3300 to 3500 Series monitors, consult Bently Nevada migration guide — some probes are cross-compatible.

Replacement & Compatibility FAQ
Q: Can I use a 3300/8/1 probe as a direct replacement for the 3300/5/1?
A: No. The 5 mm and 8 mm probes have different sensitivity scales and require different drivers. Substituting without recalibration will produce inaccurate readings.
Q: Is the 3300/5/1 compatible with the Bently Nevada 3500 Series monitors?
A: In many cases yes, but compatibility depends on the specific 3500 monitor card. Consult the 3500 Series compatibility matrix or contact Konmask for verification.
Q: Can I replace just the probe without replacing the extension cable and driver?
A: Only if the replacement probe is from the same matched set. Mixing unmatched components will affect system accuracy and may void API 670 compliance.
Q: Do you supply calibration certificates?
A: Yes. Calibration certificates and factory test reports are available upon request, subject to availability based on part origin (OEM new, surplus, or refurbished).
Q: What is the lead time for the 3300/5/1?
A: Lead time varies by stock availability. In-stock units ship within 3–5 business days. Out-of-stock items typically have a 4–8 week lead time. Contact us for current availability.
