Bently Nevada 330903-00-02-10-12-CN 3300 NSv Proximity Probe

The Bently Nevada 330903-00-02-10-12-CN 3300 NSv Proximity Probe is a high-performance non-contact vibration and displacement sensor, specifically designed for small machines and limited installation spaces. It belongs to the 3300 NSv (Narrow Signal Value) series, which offers accurate measurements where standard probes cannot be easily applied.

The probe works by using eddy current principles to detect shaft vibration and displacement relative to the bearing housing, making it an essential part of machinery protection and condition monitoring systems.

It is widely used in turbines, compressors, pumps, and other rotating equipment, providing reliable real-time monitoring that supports predictive maintenance and machine safety.

FAQ

Q1: How does the 330903-00-02-10-12-CN differ from standard 3300 XL probes?

A1: The NSv version is optimized for narrow installations and has a reduced linear range compared to standard XL probes.

Q2: What is the maximum cable length supported?

A2: The probe is available with 2 m, 5 m, and 9 m lengths, with system calibration depending on cable length.

Q3: Can this probe be directly connected to a monitoring system?

A3: No, it must be used with a 3300 NSv Proximitor sensor for signal conditioning.

Q4: What type of targets can the probe measure?

A4: It is designed to measure conductive metallic targets, typically steel shafts.

Q5: Is the probe affected by temperature variations?

A5: The probe includes temperature compensation within its operating range to maintain accuracy.

Q6: What is the typical system accuracy when installed correctly?

A6: System accuracy is within ±5% of the full-scale linear range when properly calibrated.

Q7: Can this probe detect both static and dynamic shaft displacement?

A7: Yes, it measures both static shaft position (displacement) and dynamic vibration.

Q8: Is shielding provided to reduce electromagnetic interference?

A8: Yes, the cable and probe assembly are shielded to prevent EMI and electrical noise.

Q9: Can it be installed in oil-lubricated machinery without protective housings?

A9: Yes, the probe tip is oil-resistant, but housings are recommended in harsh environments.

Q10: What is the probe’s role in API 670 compliance systems?

A10: It provides the required shaft vibration monitoring inputs for compliance with API 670 standards.
