Quick Detail

Description

The 330103-00-08-05-02-05 is a high-performance 3300 XL 8 mm Proximity Probe engineered by Bently Nevada for the most demanding machinery protection environments. As a core element of the 3300 XL series transducer system, this proximity probe utilizes the eddy current principle to provide continuous, non-contact measurement of vibration and shaft position. The 330103-00-08-05-02-05 generates an output voltage that is directly proportional to the distance between the probe tip and the target conductive surface, allowing for the precise monitoring of critical rotating assets.

Designed with a specific mechanical profile, this 3300 XL 8 mm Proximity Probe features an 80 mm overall case length and 0 mm unthreaded length. This configuration is optimized for sleeve-mounting or flush-mount applications where external threads are unnecessary or physically restrictive. The 330103-00-08-05-02-05 model comes with a 0.5-meter (1.6 feet) total length, making it ideal for compact installations where proximity to the junction box or proximitor is required. To ensure maximum durability, the proximity probe is built with a Polyphenylene sulfide (PPS) tip and an AISI 303/304 stainless steel case, offering exceptional resistance to chemical erosion, oil, and moisture.

Adhering strictly to the API 670 Standard, the 330103-00-08-05-02-05 ensures world-class accuracy and interchangeability across its 2 mm (80 mils) linear range. It incorporates Bently Nevada’s patented TipLoc molding technology, which creates an inseparable bond between the probe tip and the case, and CableLoc design to enhance cable pull strength (up to 330 N). This 3300 XL 8 mm Proximity Probe is also equipped with a Miniature coaxial ClickLoc connector, providing a vibration-resistant link that simplifies field installation.

Applications

Radial Vibration Monitoring in High-Speed Turbines The 330103-00-08-05-02-05 is widely used to monitor the radial shaft vibration of steam and gas turbines in power plants. Its 80 mm case length allows it to be positioned accurately within bearing housings to detect rotor imbalances or misalignments. The wide operating temperature range (-65°C to +175°C) ensures that the proximity probe provides stable, reliable data even in the extreme heat of turbine enclosures, supporting early fault detection and preventing unplanned downtime.

Axial Position and Thrust Bearing Protection In critical centrifugal compressors and pumps, monitoring the axial (thrust) position is vital to prevent catastrophic rotor-to-stator contact. The 330103-00-08-05-02-05 3300 XL 8 mm Proximity Probe provides a stable DC signal that tracks the static position of the shaft relative to the thrust bearing. Because of its 0.5-meter cable and compact form factor, it fits easily into the restricted spaces of modern compressor casings, providing a critical layer of protection for high-value industrial assets.

Hydroelectric Phase Reference and Keyphasor Signals This 3300 XL series probe is frequently applied as a Keyphasor sensor to provide timing and phase reference signals. By detecting a notch or keyway on a rotating shaft, the 330103-00-08-05-02-05 generates a once-per-turn pulse. This signal is essential for advanced diagnostic analysis, including calculating rotational speed and determining the vector phase angle, which is necessary for precision field balancing and machinery health assessment.

Specifications

Competitive Advantage

Specialized 80 mm Case for Custom Mounts The 330103-00-08-05-02-05 offers a unique advantage with its 80 mm overall case length and 0 mm unthreaded length. This design is specifically tailored for installations in smooth-bore holes or bracket systems where standard threaded probes would be difficult to adjust or secure. It provides a more stable mechanical platform for high-precision sensing in specialized machinery.

Robust Construction with Patented TipLoc Technology Durability is a hallmark of this proximity probe. The TipLoc molding method ensures the probe tip remains attached to the stainless steel body even under high-pressure or vacuum conditions. Coupled with the CableLoc design, which protects the cable-to-probe connection from mechanical stress, the 330103-00-08-05-02-05 significantly reduces the frequency of sensor failures in harsh industrial environments.

Global Hazardous Area Certifications (ATEX/IECEx/CSA) Equipped with multiple agency approvals (CSA, ATEX, and IECEx), this probe is ready for global deployment. This competitive edge allows engineers to standardize on a single probe model for international projects, knowing it meets the most stringent safety standards for explosive and hazardous atmospheres in any region.

Seamless API 670 Compatibility and Interchangeability As a genuine Bently Nevada 3300 XL component, this probe guarantees 100% interchangeability with other 3300 XL proximitors and extension cables. This "plug-and-play" capability eliminates the need for time-consuming field calibration and reduces the cost of maintaining a diverse spare parts inventory.

High Signal Integrity and Thermal Stability With a low supply sensitivity and a stable 50 Ω output resistance, the 330103-00-08-05-02-05 maintains superior signal-to-noise ratios. Its ability to operate across a broad temperature spectrum without signal drift ensures that the vibration data remain accurate, providing operators with trustworthy insights into their machinery’s condition.
