Features:
- Interface Between the Machine Internal Cavity and 3300 NSv Proximitor® Sensor System
- Combines Capability of Metric Thread Mount Displacement Detection with Chemical Resistance
- Operates in Conjunction with the 3300 NSv Transducer System and Standard 3500 Monitoring System
The 330907-05-30-05-02-05 operates as the NSv Reverse Mount Proximity Probe in a 3300 NSv transducer system, providing reliable displacement measurement of rotating machinery components from inside the machine housing. It continuously detects eddy current variations across 0.5 to 2.5 mm linear range while maintaining signal accuracy through PPS probe tip and non-armored cable construction. Seamless signal transmission is standard with the 330907-05-30-05-02-05, however using an optional CableLoc™ design will ensure 220 N (50 lb) pull strength at the connection point in demanding industrial environments. The 330907-05-30-05-02-05 has made improvements in several areas over previous RAM probe designs in addition to incorporating M10×1 metric thread capability within the 3300 NSv system.
The 330907-05-30-05-02-05 provides essential sensing functions common to the entire transducer system, and is a critical component of the measurement path, directly affecting the accuracy and reliability of the overall vibration monitoring system. One 330907-05-30-05-02-05 probe is required per measurement channel depending on the desired monitoring point. The 330907-05-30-05-02-05 occupies no rack slots and is always mounted directly inside the machine cavity (typically in an M10×1 threaded mounting position with 3.0 mm housing length and 0.5 mm unthreaded length).
For complete system operation, the 3300 NSv system requires the 330907-05-30-05-02-05 proximity probe to convert mechanical displacement into electrical signals. In addition to standard vibration measurement, the 330907-05-30-05-02-05 configuration also performs metric standard installation. The 330907-05-30-05-02-05 probe assembly executes international compatibility using the 7.5 N·m installation torque specified in the probe specifications. Using this method, the proximity probe continually ensures proper seating in metric-threaded housings. If the system detects that the probe signal is compromised (outside configured sensitivity of 7.87 V/mm or resistance tolerance of 4.2 Ω ± 0.5), it will indicate a fault condition in the monitoring system and require probe inspection.
The 330907-05-30-05-02-05 Bently Nevada NSv Reverse Mount Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Bently Nevada 330907-05-30-05-02-05 NSv Reverse Mount Proximity Probe Specs
General
- Manufacturer Bently Nevada
- Model 330907-05-30-05-02-05
- Condition New Original ready stock
- Product Family 330907-05-30-05-02-00,330907-05-30-05-02-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.
- Small Target Monitoring: Ideal for measuring radial vibration on shafts smaller than 51mm (2 in) or axial position on flat targets smaller than 15mm (0.6 in).
- Restricted Space Installations: Used in areas with counterbore, side-view, or rear-view restrictions that limit standard sensors.
- Harsh Chemical Environments: Features a polyphenylene sulfide (PPS) tip and improved chemical resistance compared to earlier 3300 RAM models, making it suitable for process compressors.
- Specific Compressor Applications: Widely used in centrifugal air compressors, refrigeration compressors, and process gas compressors.
- System Components: For a complete 3300 XL NSv Transducer System, the probe must be used with a 3300 NSv Extension Cable and a 3300 XL NSv Proximitor Sensor.
- Backward Compatibility: The NSv probe and cable are mechanically and electrically compatible and interchangeable with Bently Nevada’s previous 3300 RAM proximity probes and extension cables.
- Electrical Matching: The total electrical length (probe length + extension cable length) must match the required electrical length of the Proximitor.
- Connectors: Utilizes gold-plated brass ClickLoc connectors that lock in place to prevent loosening due to vibration.
- Target Material: Standard calibration is for AISI 4140 steel; accuracy specifications may not apply if used with other target materials.
- Hardware-Based Operation: As an analog eddy-current sensor, the probe itself does not have firmware.
- System Configuration: While the probe is passive, any associated digital monitoring systems (such as the 3500 Series Machinery Protection System) may require firmware updates to correctly interpret sensor data.
