The 330907-05-30-10-02-05 is a non-contact eddy current reverse mount probe from the 3300 XL NSv series for confined space vibration and displacement measurement. It contains a high-precision sensor tip and an integrated coaxial cable terminating in a Miniature ClickLoc connector with a connector protector.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
This specific configuration denotes a 3/8-24 UNF thread structure without armor featuring a 0.5 inch unthreaded length and a 3.0 inch overall case length. The assembly is equipped with a 1.0 meter total cable length and carries multiple international hazardous area agency approvals.
The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. The primary uses for the 3300 XL NSv Transducer System are for areas where counter bore, sideview, or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in).
The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components.
The 3300 XL NSv Transducer System has an Average Scale Factor of 7.87 V/mm (200 mV/mil), which is the most common output for eddy current transducers. Its enhanced side view and small target characteristics give it a shorter linear range than the Bently Nevada 3300 XL-series 5 and 8 mm Transducer System. The 1.5 mm (60 mils) of linear range exceeds the linear range of the 3000-series 190 Transducer System.

During the use of 330907-05-30-10-02-05, strict impedance matching must be maintained between the 1.0-meter probe cable, the extension cable, and the Proximitor sensor system length without any field cutting.
Because this unarmored model lacks metal casing protection, sharp cable bends below a 25.4 mm radius and abrasive routing wear must be avoided.
Furthermore, the reverse mount probe must be used with a dedicated housing, and the gap voltage must be precisely set to a typical center point of -9 Vdc at a 5.1 N·m installation torque to prevent saturation across its 1.5 mm linear range.
The 330907-05-30-10-02-05 utilizes TipLoc™ molding technology to join the probe tip and case, eliminating the risk of physical detachment caused by prolonged immersion in high-temperature lubricating oil. Meanwhile, the CableLoc™ design provides a powerful tensile strength exceeding 330 Newtons (75 pounds), ensuring a robust and durable connection between the cable and the probe.
It is a 3300 NSv series eddy current reverse mount proximity probe sensor.
What is the core application scenario of 330907-05-30-10-02-05?
It is applied in fluid-filmed bearing machinery with narrow clearance constraints, including centrifugal air compressors, refrigeration compressors, and process gas compressors.
Why choose 330907-05-30-10-02-05 over standard large probes?
The 330907-05-30-10-02-05 probe is preferred over large probes because its compact reverse-mount footprint enables external maintenance and precise measurement on small-diameter shafts within confined spaces.
What other components are required to work with the 330907-05-30-10-02-05 system?
A complete system requires a 3300 NSv extension cable and a 3300 XL NSv Proximitor Sensor alongside the probe.
