製品紹介
The Bently Nevada 330905-05-10-10-12-CN 3300 NSv Proximity Probe is a high-performance eddy-current proximity sensor designed for precise rotor displacement and vibration measurements in industrial machinery. Engineered for reliability and accuracy, it is commonly used in critical rotating equipment monitoring such as turbines, compressors, pumps, and generators. The probe converts shaft displacement into a measurable electrical signal that can be processed by condition monitoring systems.

FAQ
Q1: How does the 3300 NSv probe convert shaft movement to electrical signals?
A1: It uses the eddy-current principle where a conductive target influences the probe coil’s impedance, producing a voltage signal proportional to displacement.
Q2: What is the maximum cable length for reliable signal transmission?
A2: The standard probe can reliably transmit signals up to 30 meters using shielded coaxial cable without signal degradation.
Q3: Can the probe operate in high electromagnetic interference environments?
A3: Yes, the coaxial shielding and robust design minimize interference from nearby electrical equipment.
Q4: Is the probe compatible with 3300 XL monitors?
A4: Yes, the 3300 NSv series is fully compatible with both 3300 XL and NSv monitoring systems.
Q5: What is the frequency response / the probe?
A5: The probe supports 0–10 kHz, suitable for most vibration and shaft monitoring applications.
Q6: How does temperature affect probe performance?
A6: The probe operates within -40°C to +120°C; performance remains linear within this range.
Q7: What type / targets can the probe detect?
A7: Conductive metal targets such as turbine or generator shafts. Non-metallic materials cannot be detected.
Q8: How is the probe grounded to avoid noise?
A8: The shielded coaxial cable is grounded at the monitoring system end, providing a stable reference and reducing noise.
Q9: Can the probe detect axial and radial movements?
A9: The probe measures displacement along the probe axis; multiple probes are typically arranged to detect both radial and axial motion.
Q10: Is the probe affected by lubrication or oil films?
A10: No, thin non-conductive films such as oil do not affect eddy-current measurement performance.
