Quick Detail

Description

The Bently Nevada 330905-00-08-05-02-05 is a precisely engineered member of the advanced 3300 NSv Proximity Probes family, designed to deliver exceptional accuracy and reliability in space-optimized machinery condition monitoring applications. This model is characterized by a compact overall case length of 80 mm and a short integrated total length of 0.5 meter (20 inches), making it an ideal solution for installations where sensor reach and physical footprint are critical constraints. As a sophisticated eddy current displacement transducer, it operates on the principle of electromagnetic induction to generate a highly linear voltage signal that accurately reflects the distance between its probe tip and a conductive target. This enables precise, simultaneous measurement of both dynamic vibration and static axial position for vital assets such as high-speed gearboxes, compact compressors, and integrated motor-pump sets.

Engineered for robust performance in challenging environments, this proximity probe is built to withstand the rigors of continuous industrial operation. The probe body is constructed from durable, corrosion-resistant materials, ensuring mechanical integrity, while its design offers enhanced resistance to common industrial contaminants like lubricants and process fluids. It is certified with Multiple Approvals, affirming its suitability for use in various regulated and demanding settings. The probe features a secure Miniature coaxial ClickLoc connector system, which includes a connector protector to safeguard against accidental damage and ensure a vibration-resistant, reliable electrical connection that is crucial for maintaining signal integrity in high-vibration machinery.

The 330905-00-08-05-02-05 is defined by its precise electrical characteristics, including a recommended gap setting of 1.0 mm (40 mils) and a defined linear range from 0.25 mm to 1.75 mm. It delivers a typical supply sensitivity of 7.87 V/mm (200 mV/mil) and operates with a low output resistance of approximately 4.0 Ω, ensuring stable signal transmission with minimal loss. Capable of reliable operation across a vast operating and storage temperature range from –52 °C to +177 °C, this sensor guarantees consistent performance under extreme thermal conditions.

Applications

1. Precision Monitoring in Compact and High-Speed Machinery

With its 80 mm case and 0.5-meter cable, this probe is perfectly suited for vibration and position monitoring in spatially constrained equipment such as turbochargers, small gas turbines, high-speed spindles, and auxiliary drives within larger units. Its compact form factor allows for installation in tight bearing housings or between closely spaced components, providing critical data without interfering with the machine's compact design.

2. Retrofit and Upgrade Projects with Legacy Systems

This model serves as an excellent direct-replacement or upgrade component for existing 3300 series installations. Its standardized electrical interface and mechanical dimensions allow for seamless integration into legacy monitoring architectures, enabling users to enhance system reliability and take advantage of the NSv series' improved performance without the need for extensive system redesign or recalibration.

3. Stable Sensing in Controlled but Demanding Environments

Ideal for applications within machinery that operates in environments with controlled exposure to oils, coolants, and moderate temperatures—such as in manufacturing plants, test stands, or enclosed compressor packages. Its robust construction and stable electrical output ensure long-term, maintenance-free monitoring, supporting condition-based maintenance strategies for critical mid-range industrial assets.

Specifications

Competitive Advantage

1. Space-Optimized Design Without Compromising Performance

This probe delivers the full performance pedigree of the 3300 NSv series in a compact 80 mm package with a short 0.5-meter cable. This design provides a critical advantage for OEMs and system integrators working within strict spatial limitations, enabling high-fidelity monitoring in applications where larger probes simply cannot fit, without sacrificing measurement accuracy or signal stability.

2. Secure and Reliable Connection Architecture

The inclusion of the Miniature coaxial ClickLoc connector paired with a dedicated connector protector offers a superior connection solution. This system ensures a secure, vibration-proof, and environmentally shielded interface between the probe and its cable, drastically reducing the risk of signal interruption, connector damage, or accidental disconnection—a common point of failure in high-vibration industrial settings.

3. Exceptional Signal Stability Across Operational Extremes

Engineered for remarkable consistency, this probe operates with a low and stable output resistance (~4.0 Ω) and maintains its calibrated supply sensitivity across an exceptionally wide temperature range from –52 °C to +177 °C. This ensures that the accuracy of vibration and position measurements remains uncompromised by fluctuations in ambient temperature or supply voltage, providing dependable data for both protection and analysis purposes in variable operating conditions.
