Description

The Bently Nevada 330901-05-55-05-11-05 is a 3300NSv Proximity Probe with 1/4-28 UNF thread and without armor, as a core component of the 3300XL NSv Proximity Transducer System. The 330901-05-55-05-11-05 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 330901-05-55-05-11-05 are for areas where counter bore, side view, or rear view restrictions limit the use of standard Bently Nevada 3300 and 3300XL 5mm and 8mm Transducer Systems.

The 330901-05-55-05-11-05 is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51mm (2in) or axial position on flat targets smaller than 15mm (0.6in). The 330901-05-55-05-11-05 is primarily used in the following applications on fluid-filmed bearing machines where a small shaft or reduced side-view is present: radial vibration and radial position measurements, axial (thrust) position measurements, tachometer and zero speed measurements, and phase reference (Keyphasor signals).

The 330901-05-55-05-11-05 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 3300XL-series 5mm and 8mm Transducer System. The 1.5mm (60 mils) of linear range of the 330901-05-55-05-11-05 exceeds the linear range of the 3000-series 190 Transducer System.

The Bently Nevada 330901-05-55-05-11-05 3300 NSv Proximity Probe is a compact 1/4-28 UNF threaded, non-armored eddy current proximity probe for applications with limited installation space, such as centrifugal compressors, refrigeration compressors, and process gas compressors. The 330901-05-55-05-11-05 operates as part of the 3300 XL NSv Proximity Transducer System, providing accurate shaft vibration, shaft position, and Keyphasor® measurements when paired with a compatible 3300 XL NSv Proximitor® Sensor and extension cable.

The Bently Nevada 330901-05-55-05-11-05 3300 NSv Proximity Probe features a 0.5 in (12.7 mm) unthreaded length, 5.5 in (139.7 mm) overall case length, 0.5 m (20 in) integral cable, Miniature ClickLoc® connector with connector protector and FluidLoc® cable (Option 11), and Multiple Agency Approvals (Option 05) for hazardous-area installations.

The 330901-05-55-05-11-05 Bently Nevada 3300 NSv Probe, 1/4-28 UNF thread,without armor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

When combined with a 3300 XL NSv Proximitor Sensor and NSv extension cable, the 330901-05-55-05-11-05 provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. The system using the 330901-05-55-05-11-05 can measure both static (position) and dynamic (vibration) data. The 330901-05-55-05-11-05 delivers a linear range of 1.0 mm (40 mils), beginning at approximately 0.2 mm from the target surface. The incremental scale factor of the 330901-05-55-05-11-05 is 7.87 V/mm (200 mV/mil) ±5% typical, including interchangeability error. 
  • Vibration/Position Monitoring: Measures probe tip-to-shaft distance for radial vibration and axial thrust
  • Fluid-Film Bearing Machines: Monitors rotor displacement within bearings to prevent catastrophic failure
  • Oil/Gas Compression: Designed for pipelines/extraction compressors with intrinsically safe part
  • Petrochemical Refining: FluidLoc sealing prevents oil/moisture/chemical wicking into dry areas
  • Hazardous Locations: Pre-certified CSA/ATEX/IECEx for compliance in flammable gas/dust environments

ClickLoc Interconnect: Align the probe's male coaxial ClickLoc connector with the female side of the 3300 NSv extension cable. Push and turn until it locks firmly. Do not use pliers, as this can crush the internal gold-plated pins.
Environmental Protection: Wrap the locked probe-to-cable junction with a Bently Nevada Connector Protector or silicone self-fusing tape to block oil, water, and process chemicals.
Proximitor Core Grounding: Ensure the outer case of the probe is solidly bonded to the machinery earth ground. Connect the opposite end of the 75-ohm triaxial extension cable directly to the "PROBE" input terminal of your 3300 XL NSv Proximitor Sensor

Technical notes

The 330901-05-55-05-11-05 operates over a standard temperature range of -52°C to +177°C (-62°F to +350°F). For applications in which the probe lead may exceed the standard 177°C (350°F) temperature specification, an Extended Temperature Range (ETR) probe option is available with an extended temperature rating up to 218°C (425°F) at the probe tip. The 330901-05-55-05-11-05 is designed to seal differential pressure between the probe tip and case using a Viton® O ring sealing material.

FAQs

    +
    The Bently Nevada 330901-05-55-05-11-05 is a high-performance proximity probe from the 3300 XL NSv (Narrow System variant) Transducer Series.
  • What is the primary function of this probe?

    +
    It is a non-contact eddy current sensor. It transforms physical mechanical movement into precise electrical metrics, allowing operators to monitor vibrations and shaft positions to prevent catastrophic machinery failures.C
  • What equipment does this probe pair with?

    +
    The 330901 probe must be paired with a matching NSv Proximitor sensor and an extension cable. Using it with standard 3300 XL Proximitors without recalibration will cause measurement errors.
  • What is the nominal sensitivity?

    +
    The nominal sensitivity for the 3300 NSv system is 7.87 V/mm (200 mV/mil).
