Bently Nevada NSv 330980-50-05 5m Proximity System

Product Overview

The Bently Nevada 330980-50-05 is a 3300 XL NSv Proximity Transducer System designed for vibration and position monitoring in space-constrained rotating machinery. The system consists of an NSv proximity probe, extension cable, and Proximitor Sensor, delivering an average scale factor of 7.87 V/mm (200 mV/mil) across a 1.5 mm (60 mils) linear range. It is ideal for centrifugal air compressors, refrigeration compressors, process gas compressors, and other equipment with tight installation clearances.

• 1.5 mm linear range covers radial vibration, axial position, tachometer, and zero-speed applications

Applications

• Centrifugal air compressor vibration monitoring
• Refrigeration compressor shaft position tracking
• Process gas compressor casing vibration measurement
• Small shaft diameter machinery where probe clearance is limited
• Radial vibration, axial position, tachometer, zero-speed, and phase reference measurements

FAQ

Q: How do I decode the Bently Nevada 3300 XL NSv Proximitor suffix code?
A: The suffix uses three digits: first digit = system length (5 = 5.0 m, 7 = 7.0 m, 9 = 9.0 m); second digit = mounting (0 = panel, 1 = DIN-rail); third digit = approvals (0 = none, 5 = multiple). For 330980-50-05, this decodes to 5.0 m system length, panel mount, with multiple agency approvals.

Q: What does NSv stand for?
A: NSv stands for Narrow Side-view, indicating a compact probe design with a smaller physical diameter for restricted-space installations.

Q: Can I use the 330980 system with existing 3300 XL monitors?
A: Yes. The 3300 XL NSv system is backward compatible with 3300 XL series monitors and can replace 3300 RAM and 3000/7000 series 190 transducer systems.

Q: What is the difference between 330980-50-05 and 330980-51-05?
A: 330980-50-05 is panel mount; 330980-51-05 is DIN-rail mount. Both have 5.0 meter system length and multiple approvals.

Q: Is the probe included with the 330980-50-05?
A: The 330980 part number refers to the Proximitor Sensor. The complete system requires ordering the NSv probe and extension cable separately.

Installation Guide

1. De-energize the machinery and monitoring system before installation
2. Mount the Proximitor Sensor in a panel using the mounting hardware provided
3. Install the 3300 NSv proximity probe in the machine housing at the specified location
4. Connect the NSv extension cable between the probe and the Proximitor Sensor
5. Wire -17.5 to -26 Vdc power to the SpringLoc terminals with correct polarity
6. Route the output signal to the monitor input channel
7. Set the probe gap to the center of the 1.5 mm linear range
8. Power on and verify the output voltage matches the 7.87 V/mm scale factor

Selection Tips

• Select 330980-50-05 for panel-mounted 5.0 meter NSv systems with multiple agency approvals
• For DIN-rail mounting, choose 330980-51-05
• For 7.0 meter system length, select 330980-70-05 (panel) or 330980-71-05 (DIN)
• For 9.0 meter system length, select 330980-90-05 (panel) or 330980-91-05 (DIN)
• Without agency approvals, 330980-50-00 (panel) or 330980-51-00 (DIN) are available
• Verify machine clearance allows 5 mm probe installation before ordering
• For standard 8 mm probe applications, consider the 3300 XL 8 mm transducer system
