Bently Nevada 330903-04-10-10-01-00 3300 XL NSv Proximity Probe

Description

The 330903-04-10-10-01-00 is an M8x1 thread 3300 XL NSv proximity probe, configured with a 0.4 in (approx. 10 mm) unthreaded length (Option 04), 1.0 m total length (Option 10), and a standard ClickLoc connector with connector protector (Option 01). This non-contact, eddy-current transducer is a core component of the 3300 XL NSv Proximity Transducer System, specifically engineered for applications with restrictive target area requirements or tight installation clearances where standard proximity systems are physically impractical.

This configuration is designed for high-frequency measurements on fluid-film bearing machinery, such as small-bore compressors, aeroderivative turbines, and high-speed equipment. The NSv system provides high sensitivity for radial vibration, axial position, and tachometer signals on shafts smaller than 51 mm (2.0 in) or flat targets smaller than 15 mm (0.6 in). The included connector protector (Option 01) ensures the electrical integrity of the miniature ClickLoc connection against environmental contaminants in industrial settings.

Features

• Option 04: 0.4 in (approx. 10 mm) unthreaded probe body length
• Option 10: 1.0 m total system length (probe + extension cable interface)
• Option 01: Miniature coaxial ClickLoc connector with integrated connector protector
• Option 00: Agency approval not required
• Thread Type: M8x1 metric threading
• Non-contact measurement: Eddy-current sensing for vibration and position
• FluidLoc compatibility: Designed for reliable performance in oil-exposed environments

Applications

• Radial vibration and radial position measurements on small-diameter shafts
• Axial (thrust) position measurements for small target geometries
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signal acquisition
• Centrifugal air and refrigeration compressors
• Process gas compressors and aeroderivative turbines

Installation Guidelines

Ensure the probe is installed with the specified gap of 1.0 mm (40 mils) from the target. Use Bently Nevada-supplied extension cables and Proximitor sensors to maintain system linearity. The connector protector provided with Option 01 must be correctly seated on the female connector to prevent fluid ingress. Verify that field wiring uses three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the Proximitor sensor and the monitoring system.
