Quick Detail

Description

The 330980-70-CN 3300 XL NSv Proximitor Sensor is a high-performance proximity transducer specifically designed for advanced industrial automation applications. Engineered for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machinery with constrained installation spaces, the 3300 XL NSv Sensor excels in environments where traditional transducer systems cannot be applied due to size limitations or complex mounting conditions. Its compact and versatile design allows seamless integration into systems requiring high-density DIN-rail installations or conventional panel-mounted configurations, making it an ideal solution for modern automated facilities.

Primarily, the 3300 XL NSv Proximitor Sensor is intended for applications where restricted counter bore, side-view, or rear-view clearance limits the use of standard Bently Nevada 3300 and 3300 XL 5 mm or 8 mm transducer systems. This sensor is particularly effective for measuring radial vibration on shafts smaller than 51 mm (2 in) and axial position on targets less than 15 mm (0.6 in), providing accurate monitoring of small-scale machinery. Key automation uses include radial vibration and shaft position measurement, axial (thrust) position detection, tachometer and zero-speed sensing, as well as phase reference signal (Keyphasor) generation.

Upgrading to the 330980-70-CN 3300 XL NSv Proximitor Sensor from older 3300 RAM systems is straightforward, as existing probes, extension cables, and monitoring systems are compatible. For users transitioning from 3000-series or 7000-series transducer systems, the upgrade involves replacement of the probe, extension cable, and Proximitor Sensor with NSv components, ensuring consistent and reliable system performance. Featuring an average scale factor of 7.87 V/mm (200 mV/mil), this sensor provides standard eddy current transducer output while delivering superior side-view and small-target detection capabilities. Its 1.5 mm (60 mils) linear range surpasses that of the legacy 3000-series 190 Transducer System, allowing precise measurements in compact spaces.

In addition, the 3300 XL NSv Proximitor Sensor incorporates enhanced RFI/EMI immunity, meeting European CE mark requirements without specialized mounting. SpringLoc terminal strips simplify field wiring, enabling rapid, secure connections without specialized tools. This combination of compact design, robust signal accuracy, and ease of installation makes the 330980-70-CN 3300 XL NSv Proximitor Sensor a critical component for modern industrial automation, ensuring reliable, high-fidelity performance in demanding operational environments.

Applications

Industrial Compressors and High-Speed Machinery

The 3300 XL NSv Proximitor Sensor (model 330980-70-CN) is specifically designed for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other high-speed rotating machinery. Its compact design allows installation in machines with tight space constraints, making it ideal for areas where traditional transducer systems cannot fit.

Radial and Axial Vibration Monitoring

This sensor is widely used for precise radial vibration and shaft position measurements, as well as axial (thrust) position monitoring on fluid-filmed bearing machines. Its linear range of 1.5 mm (60 mils) and high output sensitivity (7.87 V/mm or 200 mV/mil) enable accurate detection of even small movements, ensuring reliable machinery protection and performance monitoring.

Tachometer and Phase Reference Applications

The 3300 XL NSv Proximitor Sensor also supports tachometer and zero-speed measurements, providing accurate speed and phase reference signals (Keyphasor) for critical rotating equipment. Its ability to handle small shaft diameters (under 51 mm) or flat targets less than 15 mm makes it suitable for specialized applications where precision is essential.

Upgrades and System Integration

This Proximitor Sensor is compatible with upgrades from older 3300 RAM, 3000-series, or 7000-series transducer systems. Existing probes, extension cables, and monitoring systems can be reused when upgrading to the 3300 XL NSv system, allowing cost-effective modernization of existing machinery.

Panel and High-Density Mounting Flexibility

The 330980-70-CN sensor supports both panel mount and high-density DIN-rail configurations. Its A380 aluminum construction ensures durability, while SpringLoc terminal strips simplify field wiring. Improved RFI/EMI immunity guarantees stable performance even in environments with strong electromagnetic interference, meeting European CE mark standards without special mounting requirements.

Specifications

Competitive Advantage

Compact Design for Tight Installations

The 3300 XL NSv Proximitor Sensor is engineered to operate in environments with severe space constraints. Its slim profile allows panel or high-density DIN-rail mounting, making it ideal for applications where traditional Bently Nevada 3300 or 3300 XL transducers cannot fit. This compact design also supports small target measurements, including shafts under 51 mm (2 in) in diameter and flat targets smaller than 15 mm (0.6 in).

Versatile Application Compatibility

This Proximitor Sensor works seamlessly with centrifugal air compressors, refrigeration compressors, process gas compressors, and other fluid-filmed bearing machines. It supports radial vibration, axial (thrust) position, tachometer, zero speed, and Keyphasor signal measurements. Users can upgrade from 3300 RAM, 3000-series, or 7000-series systems without needing to overhaul the entire monitoring setup, thanks to compatibility with existing probes and extension cables in certain cases.

Enhanced Measurement Performance

With a linear range of 1.5 mm (60 mils) and an average scale factor of 7.87 V/mm (200 mV/mil), the 3300 XL NSv Sensor provides highly precise and reliable eddy current measurements. Its sideview and small target optimization offer superior performance over older 3000-series 190 Transducer Systems, ensuring accurate vibration and position detection even in compact or high-density machinery environments.

Robust Electrical and Environmental Features

The sensor features improved RFI/EMI immunity, enabling CE mark compliance without special installation requirements. It operates reliably across a wide temperature range (-52°C to +100°C operating, -52°C to +105°C storage) and 100% condensing humidity conditions when connectors are protected. SpringLoc terminal strips allow for fast, secure wiring without specialized tools, minimizing installation errors and downtime.

Proven Reliability and Regulatory Compliance

Constructed with durable A380 aluminum and multiple agency approvals, the 3300 XL NSv Proximitor Sensor ensures long-term reliability in harsh industrial environments. Its resistance to voltage fluctuations (<2 mV change per volt of input) and robust construction make it an ideal solution for critical automation systems requiring continuous, accurate monitoring.
