Quick Detail

Description

The 330980-51-CN 3300 NSv Proximity Probes are precision non-contact eddy current sensors specifically developed for machinery condition monitoring applications where installation space is limited and measurement reliability is critical. As part of the advanced 3300 NSv transducer system, the 3300 NSv Proximity Probes provide accurate and stable displacement measurement by converting the distance between the probe tip and a conductive target into a proportional voltage signal. This measurement principle enables effective monitoring of vibration, shaft position, and dynamic movement in a wide range of rotating machinery.

Designed to support modernization and system upgrades, the 3300 NSv Proximity Probes are fully compatible with existing monitoring infrastructures while offering improved performance in compact installations. Compared with conventional proximity probes, the reduced probe diameter and optimized geometry of the 3300 NSv Proximity Probes allow reliable side-view and close-clearance measurements in tight bearing housings, densely packed machinery, and retrofit projects where space constraints previously limited sensor placement.

The 3300 NSv Proximity Probes operate with a standard system scale factor of 7.87 V/mm (200 mV/mil) and support a linear measurement range of up to 1.5 mm (60 mils). This linear and repeatable response ensures high-fidelity detection of shaft vibration, axial displacement, and mechanical movement under both steady-state and transient operating conditions. The recommended nominal gap of 1.0 mm (40 mils) enables consistent signal output and long-term trend stability for predictive maintenance programs.

Applications

1.Space-Constrained Machinery Vibration Monitoring

The 3300 NSv Proximity Probes are specifically designed for vibration monitoring in machinery where installation space is limited. Their compact form factor allows accurate radial vibration measurement in tight bearing housings, side-view installations, and densely packed equipment layouts, enabling reliable monitoring without mechanical redesign.

2.Shaft Position and Displacement Measurement

By maintaining a linear voltage output relative to probe-to-target distance, the probes are used for precise shaft position and displacement monitoring. This application is critical for detecting axial movement, thermal growth, and mechanical drift in compressors, turbines, and pumps, helping prevent contact-related failures.

3.Retrofit and System Upgrade Projects

The 3300 NSv Proximity Probes are well suited for upgrading legacy proximity measurement systems. They support integration into existing monitoring infrastructures while offering improved performance in compact spaces, reducing downtime and installation complexity during modernization projects.

4.Harsh Industrial Environment Operation

With compatibility for FEP-insulated and armored extension cables, the probes are applied in environments with oil, moisture, vibration, and temperature variation. They provide stable measurement signals in power plants, petrochemical facilities, and heavy industrial machinery operating under continuous load.

Specifications

Competitive Advantage

1.Compact Design Optimized for Limited Installation Space

The reduced physical size of the 3300 NSv Proximity Probes enables accurate measurements in locations where standard proximity probes cannot be installed. This design advantage allows reliable side-view sensing and close-clearance monitoring without compromising signal quality.

2.Stable and Linear Measurement Performance

With a defined linear range and controlled electrical characteristics, the probes deliver repeatable and low-noise output signals. Low supply sensitivity minimizes the influence of power fluctuations, ensuring consistent vibration and displacement data for condition monitoring systems.

3.Strong Compatibility for Modernization and Retrofit

The 3300 NSv Proximity Probes support seamless integration with existing transducer systems and monitoring platforms. This compatibility reduces engineering effort, shortens commissioning time, and lowers overall upgrade costs for industrial users.

4.Durability for Long-Term Industrial Use

Designed for continuous operation in demanding environments, the probes maintain reliable performance under vibration, temperature variation, and mechanical stress. When combined with appropriate cabling options, they offer extended service life and reduced maintenance frequency.
