Bently Nevada 330904-00-140-05-02-00 3300 XL NSv Proximity Probe

Description

330904-00-140-05-02-00 is a 3300 XL NSv proximity probe configuration designed for shaft displacement measurement in applications where standard 3300 XL probes are not suitable. This unit features a 0.0 in unthreaded length (Option 00) and a 1.40 in case length (Option 140). With a 0.5 m total length (Option 05) and a standard miniature ClickLoc connector (Option 02), this probe provides consistent performance in small-bore machinery or equipment with limited target surface area, requiring no specific hazardous area agency approvals (Option 00).

The 3300 XL NSv system functions as a non-contact, eddy-current displacement measurement chain. It is engineered specifically to operate with reduced target sizes and restricted clearances where traditional transducers might suffer from side-viewing interference. The probe is compatible with the 330980 Proximitor Sensor and 330930 extension cable to maintain the required impedance match for linear voltage output.

Features

• Option 00: 0.0 in unthreaded length configuration
• Option 140: 1.40 in case length for space-constrained mounting
• Option 05: 0.5 m system cable length
• Option 02: Miniature ClickLoc connector for secure, reliable signal path
• Option 00: No agency approval required for non-hazardous installations
• Optimized for reduced target geometry applications

Applications

• Small-bore machinery and high-speed equipment
• Aeroderivative gas turbines
• Machinery with tight clearance limitations
• Axial position and shaft vibration monitoring where standard target areas are unavailable

Installation Guidelines

Ensure the probe is installed with appropriate clearance from the target material according to the NSv system datasheet. Use caution when tightening the locknuts to avoid damaging the probe threads. Shielded extension cables must be routed away from high-voltage AC sources to prevent induced noise on the transducer output. For best results, verify proper gap voltage settings during initial commissioning using the associated 330980 Proximitor Sensor.

Compliance and Certifications

This configuration (Option 00) does not carry specific hazardous area certifications. Users requiring CSA, ATEX, or IECEx approvals must select an alternative option code during the ordering process.
