Description

The Bently Nevada 330101-00-43-15-02-05 is a high-precision 8 mm proximity probe engineered for continuous non-contact vibration and shaft position monitoring in critical industrial rotating machinery. As a key component of the Bently Nevada 3300 XL proximity transducer chain, this probe utilizes eddy-current measurement principles to deliver exceptionally accurate displacement signals. Operating alongside a compatible 3300 XL Proximitor sensor and an extension cable, it enables machinery monitoring systems to track critical dynamic parameters such as radial vibration, axial thrust position, and rotor eccentricity.

This specific configuration is optimized for installations that require direct-mount casing insertion without external physical protection armor. It features standard 3/8-24 UNF threading with a fully threaded case length of 4.3 inches (0.0-inch unthreaded length) and a total probe length of 1.5 meters. Equipped with a standard 75 Ohm coaxial cable terminated in a miniature ClickLoc coaxial connector, this configuration guarantees stable electrical transmission and contact integrity. Additionally, this SKU features the -05 agency approval option, certifying it with CSA, ATEX, and IECEx hazardous area approvals for safe deployment in environments where explosive or flammable gases may be present.

Features

• 8 mm tip diameter optimized for high-precision non-contact eddy-current displacement measurements
• Fully threaded 4.3-inch stainless steel case with 0.0-inch unthreaded length for flush housing mounting
• Standard FEP-insulated coaxial cable terminated in a miniature gold-plated ClickLoc connector
• Non-armored cable configuration for flexible, lightweight routing in clean or low-abrasion environments
• Constructed with a rugged polyphenylene sulfide (PPS) tip and AISI 303/304 stainless steel case
• Built-in Viton O-ring provides a robust differential pressure seal between probe tip and case
• Excellent temperature stability, functioning reliably in industrial thermal extremes

Applications

The Bently Nevada 330101-00-43-15-02-05 probe is designed for critical heavy-industry machinery protection, including:

• Steam and gas turbine shaft vibration and axial displacement monitoring
• Centrifugal compressor and high-pressure pump rotor position tracking
• Industrial fan, blower, and gearbox shaft movement measurement
• Large electrical motor and generator bearing housing monitoring
• Permanent turbine-generator supervisory instrumentation (TSI) installations in classified hazardous zones

Installation Guidelines

To ensure precise transducer calibration and long-term mechanical stability, adhere to the following installation rules:

• Probe Gap: Install the probe tip at the appropriate distance from the target surface (typically 1.27 mm or 50 mils for standard calibration in 3300 XL 8 mm loops).
• Torque Control: Thread the probe case into the bracket or housing with a recommended torque of 11.2 N-m (100 in-lbf). Do not exceed the absolute rated torque of 33.9 N-m (300 in-lbf).
• Cable Integrity: Ensure the non-armored FEP cable is routed through protective conduit or trays to prevent crushing. Observe a minimum bend radius of 25.4 mm (1.0 in).
• Grounding Practices: Isolate the coaxial connector shield from the machine casing and ensure proper single-point grounding at the Proximitor sensor or barrier terminal assembly.
• Environmental Protection: Protect the probe and cabling from temperatures outside the limits of -52 degC to +177 degC. Prevent exposure below -34 degC to protect the Viton pressure seal.
