Quick Detail

Description

The 330101-00-25-05-02-05 is a high-precision 3300 XL 8 mm Proximity Probes unit, serving as a fundamental non-contacting sensor for advanced machinery condition monitoring. As a critical component of the Bently Nevada 3300 XL 8 mm Proximity Probes ecosystem, this device utilizes eddy current technology to measure the static and dynamic distance between the probe tip and a conductive target, such as a rotating shaft. The 330101-00-25-05-02-05 is specifically designed to provide a linear voltage output that corresponds to displacement, making it indispensable for identifying vibration issues, thermal expansion, and rotor position in high-value industrial assets.

Configured with a 2.5-inch overall case length and a 0-inch unthreaded length, the 330101-00-25-05-02-05 offers a streamlined profile for mounting in standard bearing housings. This model of 3300 XL 8 mm Proximity Probes includes a 0.5-meter (1.6 feet) integrated cable, optimized for short-reach connections to extension cables or local junction boxes. The probe tip is manufactured from high-grade Polyphenylene Sulfide (PPS), an engineering plastic known for its extreme chemical resistance and thermal stability. This allows the 330101-00-25-05-02-05 to maintain signal accuracy within its 2 mm (80 mils) linear range, even when submerged in hot lubricating oils or exposed to industrial contaminants.

Applications

The 330101-00-25-05-02-05 is primarily used for radial vibration monitoring in critical rotating machinery such as centrifugal compressors, steam turbines, and large-scale pumps. By detecting minute shaft oscillations within its 2 mm linear range, the probe provides real-time data to identify imbalances, misalignments, or bearing wear. Its 2.5-inch case length and 0.5-meter cable make it an ideal fit for standard bearing housings where a non-contacting eddy current sensor is required to safeguard high-speed rotors from catastrophic failure.

In the power generation and oil & gas sectors, this 3300 XL 8 mm Proximity Probe is frequently deployed for axial (thrust) position measurement. Monitoring the axial movement of a shaft is vital for preventing thrust bearing damage and ensuring operational clearances are maintained. The probe's wide operating temperature range (-65°C to +165°C) and PPS tip material allow it to function reliably in the harsh, high-heat environments typical of gas turbine exhaust sections and high-pressure steam lines.

This probe also serves as a high-fidelity Keyphasor reference sensor for rotational speed detection and phase angle analysis. By observing a keyway or notch on the shaft, the 330101-00-25-05-02-05 generates a precise pulse used by monitoring systems to synchronize vibration data. Its CSA, ATEX, and IECEx approvals ensure that these critical timing signals are captured safely in hazardous locations, supporting complex diagnostic analysis and balancing procedures for large-scale industrial machinery.

Specifications

Competitive Advantage

Patented ClickLoc Connector and Robust Interconnects The 330101-00-25-05-02-05 features the Miniature ClickLoc coaxial connector, which provides a secure, tactile "click" connection. This design prevents the connector from loosening due to machine vibration—a common failure point in traditional threaded connectors. This ensures 100% signal uptime and reduces the risk of false trips in critical machinery protection systems.

Extreme Environmental Resilience and Material Quality Constructed with a stainless steel (AISI 304) case and a Polyphenylene Sulfide (PPS) tip, this probe is built for longevity. It withstands temperatures up to +165°C and resists corrosion from hydrocarbons, moisture, and aggressive chemicals. This superior build quality extends the sensor's life in harsh environments, such as offshore platforms and petrochemical refineries, lowering the total cost of ownership.

Global Hazardous Area Certification and Compliance With pre-approved CSA, ATEX, and IECEx certifications, the 330101-00-25-05-02-05 is a "world-ready" component. It meets the most stringent international safety standards for explosive atmospheres, allowing engineers to standardize on a single probe model for global projects, significantly simplifying the regulatory approval process and safety audits.
