Quick Detail

Description

The 330905-00-12-10-02-05 3300 NSv Proximity Probes are engineered as part of the Bently Nevada 3300 XL NSv Transducer System, offering precise and reliable measurements in demanding industrial environments. Specifically designed for automated machinery and process control applications, these probes excel in tight installation spaces where conventional 3300 or 3300 XL 5 and 8 mm Transducer Systems cannot be used. The system is ideally suited for centrifugal air compressors, refrigeration compressors, and process gas compressors, as well as other equipment requiring high-accuracy vibration and position monitoring.

This 3300 NSv Proximity Probe series is optimized for small target and restricted side-view applications, providing exceptional performance in measuring radial vibration on shafts smaller than 51 mm (2 in) or axial displacement on targets smaller than 15 mm (0.6 in). Typical applications include:

Radial vibration and radial shaft position monitoring

Axial (thrust) position measurements

Tachometer and zero-speed detection

Phase reference (Keyphasor) signal generation

The 3300 XL NSv Transducer System allows seamless upgrades from older Bently Nevada systems, including the 3300 RAM, 3000-series, and 7000-series 190 Transducer Systems. For 3300 RAM systems, existing probes, extension cables, and monitoring hardware can be retained while integrating the 3300 XL NSv Proximitor Sensor. Upgrades from the 3000- or 7000-series require replacement of the probe, extension cable, and sensor with NSv components.

The transducer system features an Average Scale Factor of 7.87 V/mm (200 mV/mil), delivering industry-standard eddy current transducer output. Its compact side-view design ensures precise measurements in constrained areas, with a linear range of 1.5 mm (60 mils), exceeding the 3000-series 190 probe. Mechanically and electrically compatible with previous 3300 RAM probes and extension cables, the 3300 NSv Probes also provide enhanced chemical resistance, making them suitable for challenging process compressor environments.

The 3300 NSv Probes are available in multiple probe case configurations, including armored and unarmored 1/4-28, 3/8-24, M8X1, and M10X1 threads, with reverse mount options supporting 3/8-24 or M10X1 threads. All system components feature gold-plated brass ClickLoc connectors, which lock securely to prevent accidental disconnection. The TipLoc molding and CableLoc designs ensure robust mechanical integrity, providing up to 220 N (50 lb) pull strength on probe cables. For optimal reliability, connector protectors are recommended at both probe-to-extension cable and cable-to-Proximitor Sensor connections, protecting the system from liquids and maintaining signal fidelity.

With these features, the 330905-00-12-10-02-05 3300 NSv Proximity Probes offer an advanced, compact, and reliable solution for industrial automation, enabling accurate vibration and position measurements in critical machinery while supporting easy system upgrades and long-term operational stability.

Applications

The 3300 NSv Proximity Probe (Model 330905-00-12-10-02-05) is specifically engineered for high-precision vibration and position monitoring in industrial automation environments where space constraints and compact machinery pose installation challenges. This probe is widely utilized in centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines requiring accurate shaft or axial position measurements with limited mounting space.

Radial and Axial Position Measurement

This probe excels in measuring radial vibration and radial shaft position on small-diameter shafts (less than 51 mm / 2 in), as well as axial (thrust) position on compact targets smaller than 15 mm (0.6 in). Its compact M8X1 threaded design and side-view capabilities make it ideal for installations where standard transducers cannot fit due to side-view or counterbore restrictions.

Tachometer and Phase Reference Signals

The 3300 NSv Probe also supports tachometer and zero-speed measurements, providing accurate rotational speed data. It delivers reliable phase reference (Keyphasor) signals, essential for synchronizing monitoring and control systems in automated processes.

System Upgrades and Compatibility

This probe is mechanically and electrically compatible with previous Bently Nevada 3300 RAM transducers, allowing seamless system upgrades without requiring complete replacement of existing extension cables or monitoring equipment. It is also suitable as a replacement for 3000-series or 7000-series 190 Transducer Systems when upgraded with NSv-specific components.

Harsh Environment and Chemical Resistance

Constructed with AISI 304 stainless steel casing and a polyphenylene sulfide (PPS) probe tip, the 3300 NSv Probe offers enhanced chemical resistance and can withstand probe temperatures from -52°C to +177°C (-62°F to +351°F). This durability ensures long-term performance in harsh process environments, including applications involving lubricants, refrigerants, and other industrial fluids.

Small Target and Side-View Applications

Thanks to its short linear range of 1.5 mm (60 mils) and optimized side-view design, the probe is ideal for small target applications where conventional transducers fail to maintain accuracy. This feature makes it highly suitable for precise vibration monitoring in fluid-filmed bearing machines with compact layouts.

Connector and Cable Reliability

The 3300 NSv Probe comes with Miniature coaxial ClickLoc connectors and standard cables that provide secure connections, reducing the risk of signal loss. Patented designs like TipLoc and CableLoc enhance mechanical stability, preventing disconnection or movement in high-vibration environments.

In summary, the 330905-00-12-10-02-05 3300 NSv Proximity Probe is designed for precise, compact, and reliable monitoring in automated industrial systems, offering superior adaptability for tight installation spaces, small targets, and harsh operating conditions. Its compatibility with existing Bently Nevada systems further enhances its value in process automation upgrades.

Specifications

Competitive Advantage

Optimized for Tight Spaces

The 3300 NSv Proximity Probe is specifically engineered for applications with limited installation space. Its compact design and side-view configuration allow seamless integration in centrifugal air compressors, refrigeration compressors, and process gas compressors where conventional probes may not fit. The probe’s small footprint is ideal for shafts under 51 mm (2 in) in diameter and flat targets smaller than 15 mm (0.6 in), providing precise radial and axial measurements in constrained environments.

Superior Measurement Accuracy

With a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils), the 3300 NSv maintains high-precision readings even in small-target or short-range applications. Its output resistance of 50 Ω and low supply sensitivity ensure minimal voltage fluctuation, delivering consistent and reliable data for critical machinery monitoring.

Mechanical and Chemical Robustness

The probe case is constructed from AISI 304 stainless steel (SST), with a PPS probe tip, allowing it to withstand extreme operating temperatures from -52°C to +177°C (-62°F to +351°F) and resist chemical exposure common in process compressor applications. The ClickLoc connectors, combined with CableLoc design, provide exceptional mechanical stability with 220 N (50 lb) pull strength, ensuring secure connections that resist loosening or signal degradation.

Seamless System Integration and Upgradeability

The 3300 NSv system is compatible with legacy 3300 RAM probes and extension cables, enabling easy upgrades without requiring full system replacement. For older 3000-series or 7000-series systems, the NSv components provide a direct enhancement in measurement accuracy, side-view performance, and chemical resistance. This backward compatibility simplifies maintenance and reduces downtime in critical industrial operations.

Patented Reliability Features

The probe employs Bently Nevada’s patented TipLoc molding method, ensuring a durable bond between the probe tip and body. Gold-plated ClickLoc connectors prevent electrical signal loss, while connector protectors shield the connections from liquid ingress, maintaining long-term operational integrity. These features make the 3300 NSv an exceptionally reliable solution for industrial automation applications requiring continuous, high-fidelity monitoring.

Multiple Agency Approvals

The 3300 NSv Proximity Probe carries multiple agency approvals, validating its compliance with global safety and performance standards, and making it suitable for deployment in a wide range of industrial environments.
