Description
Product Overview
330171-00-16-90-01-05 is a 3300 XL series non-armored eddy current proximity probe manufactured by Bently Nevada (Baker Hughes). It applies eddy current principle for non-contact measurement of shaft radial vibration, axial thrust displacement and keyphasor speed signal on rotating machinery. This probe must work with matched 3300 XL extension cable and Proximitor sensor to deliver real-time rotor dynamic monitoring and machinery protection for turbines, compressors, generators and critical pumps.

Key Features
- Non-contact eddy current sensing, no mechanical abrasion on rotating shaft target surface
- 75-ohm triaxial cable design for excellent EMI suppression in high-noise industrial environments
- High-temperature PPS sensing tip, stable performance under high casing temperature
- Factory calibrated, superior linearity and repeatability for consistent gap voltage output
- Robust 304 stainless steel probe body, suitable for oil, dust and high-temperature harsh environments
- Fully compatible with 3300 XL Proximitor sensor series
- Non-armored lightweight structure, convenient for wiring routing inside limited mounting space
Application Scenarios
- Steam and gas turbine vibration & thrust monitoring
- Centrifugal compressors, expanders and blowers
- Turbo generator sets
- High-speed critical process pumps
- Rotating machinery protection and online condition monitoring systems
Installation & Maintenance Notes
- Ensure probe tip keeps perpendicular to the shaft target surface; install probe within the linear gap range
- Must pair with matching Bently Nevada 3300 XL extension cable and Proximitor; mismatched transducer components will reduce measurement accuracy
- Avoid sharp bending on triaxial cable, comply strictly with the minimum cable bend radius requirement
- Follow Bently single-point shielding grounding specification to minimize electrical noise interference
- Perform gap voltage inspection after installation before machinery startup
- Check cable insulation integrity and connector tightness during regular unit outage maintenance
- Recalibration is required after probe impact, cable damage or long-term continuous operation
FAQ
Q: What does the model code 330171-00-16-90-01-05 mean? A: 330171 = base part number for non-armored 5mm probe; 00 = 0-inch unthreaded tip length; 16 = 1.6-inch probe case length; 90 = total 9-meter system cable length; 01 = ClickLoc miniature coaxial connector; 05 = multi hazardous area agency approvals.
Q: What is the difference between 330171 and 330172 probes? A: 330171 series is non-armored probe; 330172 series comes with stainless steel armored cable for mechanical protection in abrasive environments.
