BENTLY NEVADA 330907-05-30-10-02-00 3300 Proximity Transducer System

3300 XL NSv Proximity Transducer System Overview

The 3300 XL NSv Proximity Transducer System is specifically designed for use with machines requiring compact installation, such as centrifugal air compressors, refrigeration compressors, and process gas compressors. The system comprises:

• 3300 NSv probe
• 3300 NSv extension cable
• 3300 XL NSv Proximitor Sensor

This system is ideal for applications where counterbore, side-view, or rear-view restrictions exist, making standard Bently Nevada 3300 and 3300 XL transducer systems unsuitable. Additionally, it is well-suited for small target applications, such as radial vibration on shafts smaller than 51 mm (2 in) or axial position measurements on flat targets smaller than 15 mm (0.6 in).

Applications

The 3300 XL NSv Proximity Transducer System is commonly used in fluid-filmed bearing machines for:

• Radial vibration and position measurements
• Axial (thrust) position measurements
• Tachometer and zero-speed measurements
• Phase reference (Keyphasor signals)

Electrical Specifications

Probe DC Resistance

Extension Cable

• DC Resistance:
  • Center conductor: 0.220 Ω/m (0.067 Ω/ft)
  • Shield: 0.066 Ω/m (0.020 Ω/ft)
• Capacitance: 69.9 pF/m (21.3 pF/ft) typical

Field Wiring

• Supported wire sizes: 0.2 to 1.5 mm² (16 to 24 AWG) or 0.25 to 0.75 mm² (18 to 23 AWG with ferrules)
• Recommended: Three-conductor shielded triad cable
• Maximum length: 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor.
• Note: Signal roll-off at high frequencies with longer wiring lengths (refer to Figures 16 and 17 for frequency response graphs).
