Quick Detail

Description

The 330901-00-12-05-02 3300 NSv Proximity Probe is a high-precision eddy current proximity sensor engineered by Bently Nevada, a global leader in industrial machinery condition monitoring and protection solutions. As a core component of the 3300 NSv product series, the 330901-00-12-05-02 3300 NSv Proximity Probe is specifically designed for non-contact displacement, vibration, and position measurement in machinery with tight mounting constraints, making it an essential tool for predictive maintenance and critical asset protection. With a compact dimension of 1.3x1.1x119cm and ultra-lightweight design of 0.02kg, the 330901-00-12-05-02 3300 NSv Proximity Probe enables seamless installation in confined spaces, while its 0.5-meter (20 in) standard cable and Miniature coaxial ClickLoc connector with protector ensure secure signal transmission and easy system integration.

Featuring the industry-standard Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil), the 330901-00-12-05-02 3300 NSv Proximity Probe delivers high-precision measurement performance, leveraging advanced eddy current technology to generate stable voltage output proportional to the distance between the probe tip and conductive target surfaces. What distinguishes the 330901-00-12-05-02 3300 NSv Proximity Probe is its "Narrow Surface" (NSv) capability—optimized for small targets and environments with limited side-view clearance, making it ideal for small-scale rotating equipment where standard probes cannot fit. The 330901-00-12-05-02 3300 NSv Proximity Probe offers a linear range of 1.8 mm, which significantly exceeds the performance of legacy 190 series transducers, while its 0in unthreaded length and 1.2 in overall case length further enhance its adaptability to tight mounting spaces.

Applications

1. Compact Rotating Machinery Monitoring

The 330901-00-12-05-02 3300 NSv Proximity Probe is ideally suited for monitoring small centrifugal compressors, high-speed pumps, and compact turbines—equipment with limited mounting space and small conductive targets. Its 0in unthreaded length, 1.2 in overall case length, and compact dimensions (1.3x1.1x119cm) allow installation in tight compartments, while the 1.8 mm linear range and NSv capability ensure accurate measurement of minute shaft displacements and vibrations in small-scale rotating assets.

2. Legacy System Upgrade & Replacement

Designed as a direct replacement for legacy 3300 RAM systems, 3000-series, and 7000-series 190 transducer systems, the 330901-00-12-05-02 3300 NSv Proximity Probe facilitates seamless system modernization. It supports cable retention when upgrading from 3300 RAM setups, reducing upgrade costs and downtime, while ensuring full signal integrity when transitioning from older 3000-series hardware to the 3300 NSv platform.

3. Extreme Temperature Environment Monitoring

With an operating temperature range of -50°C to +175°C (-65°F to +350°F), the 330901-00-12-05-02 3300 NSv Proximity Probe delivers stable performance in harsh environments such as high-temperature turbine casings, cryogenic industrial facilities, and outdoor monitoring setups. It maintains precise measurement without signal drift, making it suitable for power generation plants, oil refineries, and chemical processing facilities with extreme temperature fluctuations.

4. Shaft Displacement & Rotor Position Sensing

The 330901-00-12-05-02 3300 NSv Proximity Probe is widely used for non-contact shaft displacement detection and rotor position sensing in critical turbomachinery. Its 1.0 mm (40 mils) recommended gap setting ensures accurate measurement of minute mechanical movements, while the 45 Ω output resistance minimizes electromagnetic interference—providing reliable data for rotor balancing, axial position monitoring, and machinery health assessment.

5. Confined Space Installation Scenarios

Optimized for environments with limited side-view clearance and tight mounting constraints, the 330901-00-12-05-02 3300 NSv Proximity Probe is ideal for installation in bearing housings, bulkheads, and compact equipment enclosures. Its ultra-lightweight (0.02kg) design avoids adding extra load to precision components, while the Miniature coaxial ClickLoc connector with protector simplifies wiring in confined spaces, reducing installation labor and time.

Specifications

Competitive Advantage

1. Ultra-Compact & Lightweight Design for Confined Spaces

The 330901-00-12-05-02 3300 NSv Proximity Probe features a slim dimension of 1.3x1.1x119cm and ultra-lightweight of 0.02kg, paired with 0in unthreaded length and 1.2 in overall case length—specifically engineered for tight mounting constraints. This compact design eliminates installation barriers in small-scale machinery, bearing housings, and confined compartments, while the lightweight build avoids interfering with precision mechanical operations, a key advantage over bulkier standard probes.

2. NSv Capability for Small Target & Narrow Clearance

Unique "Narrow Surface" (NSv) optimization makes the 330901-00-12-05-02 3300 NSv Proximity Probe superior for small conductive targets and environments with limited side-view clearance. Unlike standard probes that struggle with small targets, this model maintains high precision with a 1.8 mm linear range—outperforming legacy 190 series transducers and meeting the needs of compact rotating equipment such as small centrifugal compressors and high-speed pumps.

3. Wide Temperature Adaptability for Harsh Environments

Operating stably from -50°C to +175°C (-65°F to +350°F), the 330901-00-12-05-02 3300 NSv Proximity Probe excels in extreme industrial conditions. It resists signal drift and performance degradation even in high-temperature turbine casings or cryogenic facilities, reducing maintenance frequency and downtime compared to conventional probes with narrow temperature ranges.

4. Seamless Legacy System Compatibility

As a direct replacement for legacy 3300 RAM, 3000-series, and 7000-series 190 transducer systems, the 330901-00-12-05-02 3300 NSv Proximity Probe simplifies system upgrades. It supports cable retention for 3300 RAM transitions, lowering upgrade costs, and ensures full signal integrity for older system replacements—eliminating the need for complete infrastructure overhauls, a significant advantage over non-compatible modern probes.
