Expert Review
The 330172-00-20-05-02-CN probe delivers reliable shaft vibration data. Its short 2-inch case fits tight mounting spots. 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 smart choice for compressors and turbines.
Manager’s Insight
Stock this probe for critical rotating machinery. The 12-24 hour shipping reduces downtime. Country-specific approval (CN) helps meet local rules. Short 2-inch case length is perfect for shallow mounting holes. Compare with 8mm probes if you need larger gap ranges. We recommend buying an extra extension cable 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.

Frequently Asked Questions (FAQ)
- What does “CN” approval mean?CN stands for Country Specific approvals. It meets local certificates for that region.
- 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 330191 8mm probe instead.
- Working in very high heat (above 177°C)? Check temperature class limits.
- Require armored cable? This model includes armor – good for abrasive areas.
- Short case needed? 2-inch length fits shallow holes perfectly.
- Verify connector type: ClickLoc is standard. Match with extension cable.
