Quick Detail

Description

The 3300 NSv Proximity Probe (Model 330905-00-18-05-02-05) is a high-precision eddy-current transducer designed for industrial automation systems where compact installation and high reliability are critical. Engineered for centrifugal air compressors, refrigeration compressors, process gas compressors, and other fluid-filmed bearing machines, this probe excels in applications with tight clearance or restricted sideview and rearview access. The probe’s M10X1 threaded stainless steel case, measuring 180 mm in overall length and 0.05 kg in weight, ensures durability while supporting precise vibration and position measurements on shafts as small as 51 mm (2 in). Featuring a linear range of 1.5 mm (60 mils) and a recommended gap of 1.0 mm (40 mils), the 3300 NSv provides accurate radial vibration, radial position, and axial thrust measurements even in challenging environments. Its miniature coaxial ClickLoc connector and 0.5-meter cable enable secure, vibration-resistant connections compatible with existing Bently Nevada 3300 RAM systems. The probe operates reliably in extreme temperatures from -52°C to +177°C (-62°F to +351°F), with superior chemical resistance and less than 2 mV voltage variation per volt of supply change, ensuring consistent automation performance across demanding process control applications.

Applications

1. Radial Vibration Monitoring
The 3300 NSv accurately measures radial vibrations on shafts with diameters as small as 51 mm, providing critical feedback for automated vibration monitoring systems in compressors and pumps. Its 1.5 mm linear range ensures precise detection of amplitude changes up to 60 mils.

2. Axial (Thrust) Position Measurement
Ideal for thrust bearing applications, the probe detects axial shaft displacements on flat targets smaller than 15 mm. Automation systems benefit from real-time position control, enhancing reliability and reducing mechanical wear.

3. Tachometer and Zero-Speed Detection
Integrated in automated rotating equipment, the 3300 NSv supports zero-speed detection and tachometer functions, delivering accurate rotational speed feedback for process control loops.

4. Phase Reference (Keyphasor) Signals
Used as a phase reference sensor, the probe provides Keyphasor signals with minimal electrical noise, enabling precise phase synchronization in automated machinery monitoring systems.

5. Small Target/Restricted Space Applications
Its compact 180 mm probe length and side-view capability make it suitable for automation setups where counter bore or rearview restrictions prevent standard probes, maintaining performance in limited installation spaces.

Specifications

Competitive Advantage

1. Superior Chemical Resistance
Compared with the 3300 RAM probe, the NSv probe withstands aggressive process environments, allowing integration in automated systems for chemical, refrigeration, and gas compression applications.

2. Mechanical and Electrical Interchangeability
Compatible with 3300 RAM probes and extension cables, the NSv reduces upgrade costs in automated monitoring systems, allowing seamless integration without full system replacement.

3. Robust Connector Design
Gold-plated ClickLoc connectors and CableLoc bonding deliver 220 N pull strength, ensuring secure connections in automated environments subject to vibration and movement.

4. High Temperature Operation
Operating from -52°C to +177°C, the probe supports harsh industrial automation environments, including compressors and turbines, without signal degradation or mechanical failure.

5. Precision and Reliability
With a linear range of 1.5 mm and output resistance of 50 Ω, the NSv probe offers consistent, repeatable measurements. Automation systems gain improved machine protection, reduced downtime, and extended equipment lifespan.
