330905-00-02-10-02-05 Bently Nevada Sensor 3300 NSv New Original

Product Overview

The Bently Nevada 330905-00-02-10-02-05 is a high-precision eddy current proximity transducer.

It measures dynamic vibration and axial shaft position in high-speed rotating machinery.

This compact sensor belongs to the industry-proven 3300 NSv proximity probe series.

It features a short 20 mm case length designed for tight installation spaces.

Polyphenylene sulfide tip material offers enhanced chemical resistance against aggressive process gases.

Technical Specifications

Target Machinery & Diagnostic Capabilities

• Centrifugal Gas Compressors: Monitors radial shaft vibration in tight bearing housings.
• Small Steam Turbines: Tracks dynamic axial position during rapid thermal expansion cycles.
• Turboexpanders: Detects micro-inch shaft displacement inside high-speed hydrocarbon processing units.
• Diagnostic Monitoring: Provides early detection of journal bearing tilt, rotor unbalance, and oil whip.

Selection Guide & Installation Recommendations

Choose the 330905-00-02-10-02-05 when mounting depth behind the tapped hole is extremely restricted.

The 20 mm overall case length prevents internal structural interference within compact bearing counterbores.

If your installation requires an 80 mm case length, choose model 330905-00-08-10-02-00 instead.

Ensure target shaft diameter measures at least 13 mm to maintain calibrated voltage scale factors.

Maintain a minimum cable bend radius of 25.4 mm during installation.

Global PLC Spare HUB's Insight

During a turboexpander overhaul, technicians faced severe clearance limitations inside the outboard bearing housing.

Standard 80 mm probe bodies contacted internal oil deflectors before fully threading into place.

Installing the short-body 330905-00-02-10-02-05 probe resolved the physical interference completely.

The miniature ClickLoc connector locked securely, preventing signal loss caused by high-frequency machinery vibration.

We advise verifying field cable shielding integrity before running final zero-voltage loop checks.

Frequently Asked Questions

Q1: When should I choose a 20 mm probe case instead of longer options?

A1: Select a 20 mm case length when mounting inside shallow counterbores or compact external brackets.

Q2: What signal degradation occurs over maximum field cable lengths?

A2: Field wiring over 305 meters causes high-frequency signal attenuation above 10 kHz.

Q3: Does the -05 agency approval code require specialized field wiring?

A3: Hazardous zone installations require approved intrinsically safe isolator barriers and three-conductor shielded triad cabling.

Q4: How do I verify correct probe gap positioning during setup?

A4: Measure DC output voltage between the Proximitor signal terminal and ground; -9.0 Vdc indicates a 1.0 mm gap.

Q5: Why is polyphenylene sulfide selected for the probe tip?

A5: Polyphenylene sulfide resists aggressive chemical breakdown caused by synthetic lubricants and sour process gas contaminants.
