Product Information:

The 330901-05-65-05-11-05 is an industrial-grade 8mm non-contact eddy current displacement sensor probe (8mm proximity probe), belonging to the Bently Nevada 3300 XL series. As an internationally standard hardware component in the field of rotating machinery condition monitoring and fault diagnosis, this probe is specifically designed for continuous, real-time monitoring of shaft vibration, shaft displacement, and critical phasor rotation in high-value equipment such as steam turbines, gas turbines, large compressors, fans, and pumps.

The 330901-05-65-05-11-05 can accurately convert micron-level displacement changes on mechanical surfaces into electrical signals, making it a core sensing element for preventing catastrophic damage to industrial rotating equipment. The probe features a high-strength stainless steel housing and high-temperature, corrosion-resistant PPS (polyphenylene sulfide) and Teflon insulation layers, allowing for long-term stable operation in harsh oily environments ranging from -51℃ to +177℃.

Based on its specific multi-digit suffix parameter code, the hardware configuration of 330901-05-65-05-11-05 is as follows: It adopts a 3/8-24 UNF fine-pitch standard thread housing (without reverse mounting capability); it has a 0.5-inch (approximately 13 mm) unthreaded portion and a total threaded length of 6.5 inches (approximately 165 mm) for easy deep-hole suspension mounting; it is equipped with a 0.5-meter (approximately 20-inch) long coaxial cable with a streamlined miniature coaxial connector and a standard connector protective sleeve to ensure protection from electromagnetic and mechanical damage in the field.

Features:

  • 3300 NSv Proximity Probes
  • 330901 3300 NSv Probe, 1/4-28 UNF thread, without armor
  • 3300 XL NSv Proximity Transducer System
The 3300 NSv probe and extension cable are mechanically and electrically compatible and interchangeable with Bently Nevada’s previous 3300 RAM proximity probe and extension cable. The NSv probe has increased chemical resistance compared to the 3300 RAM probe, which allows its use in many process compressor applications. The side-view characteristics of the 3300 NSv probe are also superior to those of the 3000-series 190 probe when gapping the 3300 NSv probe at the same distance from the probe target.

The 3300 NSv probe comes in varying probe case configurations, including armored and unarmored 1/4-28, 3⁄8-24, M8X1 and M10X1 probe threads. The reverse mount 3300 NSv probe comes standard with either 3⁄8-24 or M10X1 threads. All components of the transducer system have gold-plated brass ClickLoc connectors. ClickLoc connectors lock into place and prevent the connection from loosening. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body.

The 330901-05-65-05-11-05 Bently Nevada 3300 NSv Proximity Probes may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Within a comprehensive control and asset protection architecture, this probe cannot operate independently. It must be rigorously matched with the 3300 XL series extension cable and proximity sensor to form a complete 5-meter or 9-meter sensor measurement system. Ultimately, the linear voltage signal is input to the Bently Nevada 3500 mechanical protection system or distributed control system (DCS). This system is widely used in predictive maintenance systems with extremely high safety requirements (compliant with SIL2 safety integrity level) in industries such as power, petrochemicals, heavy metallurgy, and natural gas pipeline transportation. This helps companies eliminate potential equipment failures and maximize equipment uptime.

Technical notes

The 330901-05-65-05-11-05 is the Bently Nevada 3300 XL NSv narrow-edge confined eddy current displacement sensor probe. It features a 1/4-28 UNF thread and no metal armor (as indicated by the prefix 330901). This probe is designed for accurate, non-contact shaft vibration and displacement measurements in confined spaces, with small shaft diameters (less than 51 mm), or in environments with severe reverse and lateral magnetic field interference. Its hardware specifications include: a 0.5-inch (-05) threadless length, an increased overall housing length of 6.5 inches (-65) to accommodate deeper mounting openings, a 0.5-meter (-05) total cable length, and an integrated ClickLoc gold-plated miniature coaxial connector (-11) with a FluidLoc leak-proof seal. Furthermore, it supports ATEX/IECEx/HazLoc and other compatible standards. It has obtained multiple international explosion-proof and safety certifications (-05).
