        Features:

        • Direct Precision Transducer for Confined Counterbore and Restricted Clearance Machine Housings
        • Optimized Small-Target Eddy Current Sensing for Shafts Under 51 mm and Narrow Axial Targets
        • Fully Standardized Output Signal Supporting Seamless Integration with 3300 XL NSv Proximitor Systems
        The Bently Nevada 330907-05-30-10-02-05 3300 NSv Reverse Mount Probe continuously generates an eddy current field to measure dynamic shaft movement and delivers an industry-standard Average Scale Factor of 7.87 V/mm (200 mV/mil) with a 1.5 mm (60 mils) linear range. Designed specifically to resolve installation challenges where counterbore, side-view, or rear-view restrictions prevent the use of standard 5 mm and 8 mm probes, the 330907-05-30-10-02-05 effectively eliminates side-view signal interference while maintaining high measurement fidelity on small targets.

        The 330907-05-30-10-02-05 provides primary vibration sensing common to critical fluid-film bearing machinery, serving as an essential front-end component of the monitoring chain that directly impacts the accuracy of overall machinery protection systems. Depending on the machine design and monitoring requirements, multiple probes are installed near bearings in centrifugal air compressors, refrigeration compressors, and process gas compressors. Occupying a reverse-mount probe location, the 330907-05-30-10-02-05 passes through machine housings or internal brackets where rear access is required for tight clearance mounting.

        For complete measurement applications, the 330907-05-30-10-02-05 operates in conjunction with a 3300 NSv extension cable and a 3300 XL NSv Proximitor Sensor. Beyond standard radial vibration and position monitoring, this system executes axial (thrust) position tracking, tachometer/zero-speed detection, and Keyphasor phase reference signal generation. In system upgrade scenarios, the 330907-05-30-10-02-05 can replace legacy 3300 RAM probes while reusing existing cables and monitors, or replace legacy 3000-series/7000-series 190 transducers when updated alongside matching NSv extension cables and Proximitors.

        The 330907-05-30-10-02-05 Bently Nevada 3300 NSv Reverse Mount Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        General

        • Manufacturer Bently Nevada
        • Model 330907-05-30-10-02-05
        • Condition New Original ready stock
        • Product Family 330907-05-30-10-02-00,330907-05-30-10-02-CN
        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Space-Restricted Machinery: It is optimized for installations with severe physical restrictions, such as counterbores, side-view constraints, or rear-view blockages. Its specialized side-view profile prevents the probe from grounding out or experiencing cross-talk against surrounding sidewalls.
        • Small Shaft and Target Monitoring: It reliably measures radial vibration on small machine shafts (diameters under 51 mm / 2 inches) and axial (thrust) position on flat targets smaller than 15 mm / 0.6 inches.
        • Corrosive & Process Gas Environments: The materials offer enhanced chemical resistance. This makes it standard hardware for centrifugal air compressors, refrigeration compressors, and various process gas compressors.
        • Core Measurement Roles: It is widely deployed for radial vibration/position, axial/thrust displacement, tachometer/zero-speed detection, and Phase Reference (Keyphasor) signaling.
        • System Matching: The combined electrical length of the probe and extension cable must precisely match the requirement of the Proximitor Sensor (typically a 5-meter or 9-meter total system).
        • Electrical Output Compatibility: The system operates with a standard Average Scale Factor (ASF) of 7.87 V/mm (200 mV/mil). This allows it to feed directly into standard industrial monitoring platforms without custom monitor card reconfigurations.
        • Hardware Interconnect: The probe features a gold-plated brass ClickLoc connector. This design locks finger-tight to prevent loosening from machine vibration, eliminating the need for specialized termination tools.
        • Calibration & Adjustment: Any physical or environmental updates are performed through physical gap calibration of the loop or by updating the configuration software of the digital monitoring rack it feeds into.
        • Maintenance & Integrity: Asset updates involve checking mechanical tolerances, ensuring the integrity of the sealing O-rings, and verifying correct loop electrical resistance using a multimeter.
        Description
        The Bently Nevada 330907-05-30-10-02-05 probe is designed specifically for handling physical clearance constraints in tight machinery spaces, effectively solving the problem where counterbore, side-view, or rear-view restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 mm and 8 mm transducer systems. Furthermore, the 330907-05-30-10-02-05 addresses signal interference issues on smaller measurement surfaces by providing optimized target performance, making it ideal for measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in).

        In terms of application areas, the Bently Nevada 330907-05-30-10-02-05 is primarily used on fluid-film bearing machines where a small shaft or reduced side-view is present. Key machine types include centrifugal air compressors, refrigeration compressors, and process gas compressors. Within these environments, the 330907-05-30-10-02-05 probe performs essential monitoring tasks including radial vibration and radial position measurements, axial (thrust) position measurements, tachometer and zero speed measurements, and phase reference (Keyphasor) signal tracking.

        For installation and system integration, the Bently Nevada 330907-05-30-10-02-05 operates as part of the 3300 XL NSv Proximity Transducer System, which consists of the 330907-05-30-10-02-05 NSv probe, a 3300 NSv extension cable, and a 3300 XL NSv Proximitor Sensor. Electrically, it delivers an Average Scale Factor of 7.87 V/mm (200 mV/mil)—the standard output for eddy current transducers—along with a 1.5 mm (60 mils) linear range designed to exceed legacy probes while accommodating tight side-view clearances.

        Technical notes
        The 330907-05-30-10-02-05 reverse-mount probe is designed to address stringent physical limitations, such as in situations where chamfering, side-viewing, or back-viewing is restricted, making standard Bently Nevada 3300 and 3300 XL 5mm and 8mm sensor systems unusable. By optimizing the system's side-viewing and small-target detection characteristics, the 330907-05-30-10-02-05 successfully addresses key issues such as limited sensor clearance and physical installation space constraints. It offers a reliable 1.5mm (60 mil) linear range with a standard average scale factor of 7.87 V/mm (200 mV/mil), effectively overcoming the range limitations of older technologies such as the 3000 Series 190 system.
