Description

The Bently Nevada 330901-00-40-10-02-05 is a 3300 NSv (Near-Surface) Proximity Probe, a critical component of the 3300 XL NSv Transducer System. Engineered for machinery with restricted installation space, this probe is specifically designed for applications where standard 5mm or 8mm proximity probes cannot be used due to counter-bore, side-view, or rear-view limitations. It provides precise measurements for radial vibration, axial position, and phase reference (Keyphasor) signals on fluid-filmed bearing machines.

Features

• Designed for tight installation requirements where standard probes are restricted.
• Average Scale Factor of 7.87 V/mm (200 mV/mil).
• Linear range of 1.5 mm (60 mils).
• Equipped with gold-plated brass ClickLoc connectors for secure, vibration-resistant connections.
• Patented CableLoc design providing 220N (50 lb) pull strength between the probe tip and cable.
• Compatible with 3300 XL NSv Proximitor Sensors.

Applications

• Centrifugal air compressors and refrigeration compressors.
• Small-diameter shaft vibration monitoring (shafts smaller than 51mm).
• Axial position measurement on flat targets smaller than 15mm.
• Process gas compressors requiring enhanced chemical resistance.

Technical Specifications

Installation Guidelines

• Ensure the mounting hole is properly tapped and free of debris before installation.
• Recommended nominal probe gap is 1.0 mm (40 mils).
• Use a voltmeter at the Proximitor Sensor to adjust the gap until the output voltage is typically between -8 VDC and -12 VDC.
• Connector protectors are strongly recommended at all connection points to prevent moisture and liquid ingress.
• Handle with care; avoid sharp bends in the coaxial cable to maintain signal integrity.
• Always power down the monitoring system before connecting or disconnecting the probe from the extension cable or Proximitor Sensor.

FAQ

What is the primary purpose of the 3300 NSv probe?

The 3300 NSv probe is designed for machinery condition monitoring in space-constrained environments where standard-sized proximity probes are physically unable to fit or provide accurate readings due to side-view interference.

Can this probe replace older systems?

Yes, the 3300 XL NSv system is designed to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer Systems. Note that upgrades from older 3000/7000 series systems require replacing the probe, extension cable, and Proximitor Sensor.

Is the cable armor included?

No, this specific model (330901-00-40-10-02-05) is configured without armor.
