Expert Review
The 330172 probe delivers reliable shaft vibration data. Its PPS tip resists chemicals and wear. Armor protects cable in harsh industrial sites. The ClickLoc connector locks firmly – no signal loss. For 5mm systems, this model gives consistent output across -35°C to +177°C. Use it with 3300 XL Proximitor for best linearity. A top choice for turbine and compressor monitoring.
Manager’s Insight
Stock this probe for critical rotating machinery. The 12-24 hour shipping reduces downtime. Multiple approvals mean one part fits global sites. Compare with 8mm probes if you need larger gap ranges. For tight spaces, the 6.3 inch case length works well. We recommend buying an extra cable and Proximitor sensor together.
Typical Applications & Equipment
- Steam Turbines: Shaft vibration and position monitoring.
- Gas Compressors: Thrust position and eccentricity.
- Large Pumps: Bearing vibration detection.
- Fans & Blowers: High-speed shaft tracking.
- Generators: Air gap and rotor vibration.
- Paper Mills: Roller position feedback.
Compare with Similar Models
- 330173-00-06-10-02-00 – 8mm ETR Reverse Mount Probe – larger tip for bigger gaps.
- 330173-00-05-10-12-00 – 8mm ETR Reverse Mount Probe – different length options.
Frequently Asked Questions (FAQ)
- What is the difference between 330172 and 330173?330172 is 5mm probe. 330173 is 8mm probe (larger sensing range).
- Can I use this probe without a Proximitor sensor?No. You need a Bently Nevada Proximitor sensor (like 3300 XL) to get usable output.
- What happens if I exceed 7.3 N·m torque?Overtightening may strip threads or crack the probe case.
- Is the 12-month warranty worldwide?Yes. Warranty applies globally. Contact us for claims.
- How to choose between 5mm and 8mm probes?Use 5mm for small gaps (0.5-2mm range). Use 8mm for larger gaps up to 3mm.
- What shipping methods do you use?FedEx, UPS, DHL. Usually delivered in 3-7 business days.
- Can I get technical help for installation?Yes. Email sales@powergearx.com or WhatsApp +86 18030005825. We help with gap setting and wiring.
Quick Selection Guide
- Need 5mm sensing? Choose 330172 (this model).
- Need larger gap range? Pick 330173 8mm probe instead.
- Working in very high heat (above 177°C)? Check temperature class limits.
