Quick Detail

Description

The 330905-00-09-05-02-05 3300 NSv Proximity Probe is a compact, high-precision eddy current sensor engineered for industrial automation systems that require accurate vibration and position measurement in space-restricted installations. Designed as part of the Bently Nevada 3300 NSv Proximity Probe family, this model features an M10X1 stainless steel probe case, a 0.5 meter standard cable, and a 90 mm overall case length, enabling reliable integration into compressors, turbines, and rotating machinery with limited side-view clearance.

Built for continuous operation in harsh industrial environments, the probe supports a wide operating temperature range from -52°C to +177°C, while its PPS probe tip and AISI 304 stainless steel housing provide strong chemical resistance and long-term mechanical stability. With a linear measurement range of 1.5 mm and a recommended gap of 1.0 mm, the 3300 NSv proximity probe delivers stable displacement signals with an output resistance of 50 ohms and minimal sensitivity to supply voltage variation. The miniature ClickLoc coaxial connector ensures secure electrical connection and signal integrity in high-vibration automation systems.

Optimized for small targets and narrow mounting envelopes, the 3300 NSv Proximity Probe is widely used for radial vibration, axial position, phase reference, and zero-speed detection on fluid-film bearing machines. Its enhanced side-view performance and compact geometry make it an effective replacement for legacy 3300 RAM and 3000/7000 series proximity probes, supporting modernization of condition monitoring architectures without sacrificing measurement accuracy. This model meets multiple international agency approvals, ensuring compliance with global industrial automation standards.

Applications

Application 1: Centrifugal Compressor Radial Vibration Monitoring

In centrifugal air and process gas compressors, the 3300 NSv Proximity Probe measures radial shaft vibration on diameters below 51 mm. The 1.5 mm linear range and 7.87 V/mm scale factor enable precise detection of imbalance and misalignment at high rotational speeds, improving compressor reliability and uptime.

Application 2: Axial Thrust Position Measurement

For thrust bearing monitoring in rotating equipment, this proximity probe accurately tracks axial displacement on flat targets smaller than 15 mm. The recommended 1.0 mm gap ensures consistent signal output, supporting automated shutdown logic in critical machinery protection systems.

Application 3: Refrigeration Compressor Condition Monitoring

In refrigeration compressors with tight housing constraints, the 90 mm probe body and side-view optimized design allow installation where standard 5 mm or 8 mm probes cannot fit. This enables continuous condition-based maintenance within automated process plants.

Application 4: Tachometer and Zero-Speed Detection

The 3300 NSv Proximity Probe supports tachometer and zero-speed applications by detecting shaft keyways or notches with high repeatability. The stable output resistance and low supply sensitivity ensure accurate speed reference signals for PLC and DCS systems.

Application 5: Phase Reference in Turbomachinery

When used as a phase reference sensor, this model provides reliable Keyphasor-style signals for vibration analysis. Its ClickLoc connector minimizes signal interruption, supporting advanced diagnostic algorithms in online monitoring platforms.

Specifications

Competitive Advantage

Competitive Advantage 1: Optimized for Limited Installation Space

With an M10X1 thread, 0 mm unthreaded length, and compact geometry, this probe excels in confined environments where standard proximity probes cannot be installed, reducing mechanical redesign costs.

Competitive Advantage 2: Wide Operating Temperature Capability

The -52°C to +177°C operating and storage range allows consistent performance in both cryogenic and high-temperature industrial processes, outperforming many conventional proximity sensors limited to narrower ranges.

Competitive Advantage 3: High Chemical and Mechanical Durability

The combination of PPS probe tip material and 304 stainless steel housing enhances resistance to oils, process gases, and corrosive atmospheres, extending service life in harsh automation environments.

Competitive Advantage 4: Low Signal Drift and Stable Output

With less than 2 mV/V supply sensitivity and 50 ohm output resistance, the probe maintains signal stability even under fluctuating power conditions, improving data reliability for automated monitoring systems.

Competitive Advantage 5: Seamless Upgrade and System Compatibility

The 3300 NSv Proximity Probe is mechanically and electrically compatible with legacy 3300 RAM systems, enabling cost-effective upgrades without full system replacement while delivering improved side-view performance and linear range.
