Bently Nevada 330908-00-15-05-02-00 1.5-Inch Case Probe

Product Overview

The 330908-00-15-05-02-00 is a high-reliability industrial proximity probe from Bently Nevada’s specialized 3300 NSv (Narrow System) series. Engineered primarily for fluid-film bearing vibration, thrust position, and speed tracking, this non-contacting eddy current probe is optimized for applications with restricted installation space or small target shafts. It features a compact 1.5-inch AISI 304 stainless steel case, an unthreaded length profile, and an integral 0.5-meter FEP-jacketed coaxial cable terminating in a miniature ClickLoc connector. This model offers high-integrity physical sealing and enhanced chemical resistance, allowing it to interface seamlessly with industrial process compressors and high-speed turbomachinery.

Core Technical Advantages

• Enhanced Chemical Resistance: Upgraded material construction provides significantly higher chemical resilience compared to legacy 3300 RAM probes, making it safe for harsh process gas environments.
• Optimized Cross-Talk Suppression: Superior side-view characteristics over previous 3000-series 190 probes ensure precise gap measurements without interference from adjacent mechanical structures.
• ClickLoc Interconnect Security: Fitted with a miniature coaxial ClickLoc connector (02 Option Code) that establishes an IP67-rated, vibration-proof mating link with extension cables.
• Wide Thermal Range Performance: Certified to operate stably across extreme temperature boundaries from -52°C up to +177°C, maintaining signal consistency under heavy machinery operational cycles.

Technical Specifications

Engineering Installation & Maintenance

• Torque Limitations: When executing standard mounting into a threaded 3/8-24 port, apply the recommended seating installation torque of 11.3 N·m (100 in·lb). Absolute maximum rated installation torque must not exceed 33.9 N·m (300 in·lb) to prevent housing distortion. For the miniature connector-to-connector interface, use finger-tight execution up to a maximum limit of 0.56 N·m (5 in·lb).
• Thread Engagement Bound: Ensure that the maximum length of thread engagement inside the machine housing does not exceed 0.563 inches to prevent internal mechanics collision.
• Cable Bending Parameters: Maintain a minimum structural bend radius of 25.4 mm (1.0 inch) across the entire 0.5-meter FEP coaxial line during routine field wiring routing to eliminate core shielding micro-fractures.
• Target Size Guidelines: For optimum scale factor calibration, the minimum flat shaft target area diameter is 8.9 mm (0.35 in), with a recommended standard minimum of 13 mm (0.5 in). Axial position reading on smaller surfaces requires reduced gaps to maintain scale factor fidelity.

Why Choose This Model

• Backward Compatibility: Physically and electrically interchangeable with previous-generation Bently Nevada 3300 RAM proximity components, enabling easy retrofitting without modifying existing control room monitors.
• High-Frequency Signal Path: Supports a broad frequency response from 0 to 10 kHz (+0, -3 dB typical), allowing reliable vibration diagnosis up to 305 meters (1,000 feet) away using heavy-gauge three-conductor shielded triad field cables.
• Differential Pressure Sealing: Equipped with an internal Viton O-ring seal specifically designed to contain high differential pressures between the probe tip and outer case framework.

Technical FAQs

Q1: What does the -00 option code signify at the end of the part configuration?
A1: The final -00 suffix denotes that specialized agency hazardous approvals are not required for this standard stock specification model layout.

Q2: What is the Deviation from Best Fit Straight Line (DSL) error metric for this probe?
A2: The module maintains tight calibration tolerances, featuring a DSL variance of less than ±0.06 mm (±2.3 mils) over its entire 1.5 mm tracking curve.

Q3: Is this product brand new or reconditioned surplus stock?
A3: We supply this item exclusively as 100% brand new and original unit condition inside its authentic factory protective packing, covered by a full 12-month mechanical performance warranty.
