Quick Detail

Description

The 330103-00-04-20-02-05 3300 XL 8 mm Proximity Probe is engineered to deliver high-precision monitoring and measurement capabilities for advanced automation and industrial control systems. This proximity transducer system generates an output voltage directly proportional to the distance between the probe tip and the conductive surface under observation, enabling highly accurate readings of both static positions and dynamic vibrations. Its robust design ensures reliable performance in demanding industrial environments, particularly for machinery that relies on fluid-film bearing technologies.

Designed for automation professionals, the 3300 XL 8 mm probe system excels in vibration monitoring, position sensing, Keyphasor signal generation, and speed measurements. These applications are essential for predictive maintenance, machine diagnostics, and automated process control in sectors such as power generation, petrochemical, and heavy industry. The 3300 XL series is widely recognized for its compliance with API 670 standards, guaranteeing precise mechanical configuration, linear response, measurement accuracy, and stability across a broad temperature range.

A key advantage of the 330103-00-04-20-02-05 probe system is its modularity and interchangeability. All components, including probes, extension cables, and Proximitor sensors, are fully interchangeable within the 3300 XL 8 mm system. This backward compatibility extends to non-XL 3300 series 5 mm and 8 mm probes, allowing seamless integration into existing automation setups without requiring individual calibration of components. This feature reduces downtime and simplifies inventory management for maintenance teams.

The probe design incorporates several engineering improvements. The patented TipLoc molding ensures a secure and durable bond between the probe tip and its housing, while the CableLoc technology provides exceptional mechanical strength with a 330 N (75 lbf) pull resistance, securing the cable to the probe tip reliably even in high-vibration industrial environments. For applications where fluid ingress could compromise measurements, the optional FluidLoc cable system prevents oil and other liquids from entering the probe housing, maintaining sensor accuracy and protecting automation equipment.

With its combination of precision, durability, and automation-ready features, the 330103-00-04-20-02-05 3300 XL 8 mm Proximity Probe stands as a critical component in any industrial monitoring or automated control system, supporting the optimization of machine performance, predictive maintenance strategies, and overall operational efficiency. Its adaptability and high performance make it a leading choice for engineers seeking reliable, high-resolution proximity measurement solutions within automated industrial environments.

Applications

The 3300 XL 8 mm Proximity Probe is specifically designed for high-precision measurement and monitoring in industrial automation and machinery applications. Its core functionality is to provide an output voltage directly proportional to the distance between the probe tip and a conductive target, enabling accurate measurement of both static positions and dynamic vibrations.

Vibration Monitoring in Fluid-Film Bearings

The probe is ideal for vibration measurement on fluid-film bearing machines, ensuring early detection of imbalance, misalignment, or mechanical wear. With a linear range of 2 mm and a recommended radial vibration gap setting of approximately 1.27 mm (50 mils), the probe delivers precise readings that support predictive maintenance programs and minimize unplanned downtime in critical industrial equipment.

Position and Speed Sensing

Equipped with high sensitivity and low output resistance (50 Ω), the 3300 XL 8 mm probe provides reliable position monitoring for rotating machinery and automated systems. Additionally, it can serve as a Keyphasor reference sensor, delivering accurate speed and phase information for condition monitoring systems. This functionality is essential in automation setups requiring synchronized machine operations and real-time diagnostics.

Compatibility and Integration

The 3300 XL 8 mm probe system supports complete interchangeability with probes, extension cables, and Proximitor sensors, enabling easy integration into existing automation infrastructure. Its backward compatibility with non-XL 3300 series components, including 5 mm probes, allows deployment in applications with limited mounting space without compromising measurement accuracy.

Harsh Environment Applications

Constructed with AISI 303/304 stainless steel probe cases and a polyphenylene sulfide (PPS) probe tip, the probe withstands extreme operating and storage temperatures from -52°C to +177°C (-62°F to +350°F). Combined with CSA, ATEX, and IECEx approvals, it is suitable for hazardous or high-temperature industrial environments, including petrochemical plants, power generation turbines, and heavy machinery operations. Optional FluidLoc cables prevent oil or liquid ingress, ensuring stable measurements in wet or lubricated machinery.

Industrial Automation and Predictive Maintenance

The 3300 XL 8 mm probe is a critical component in automated condition monitoring systems, supporting predictive maintenance, performance optimization, and equipment safety. Its precision, durability, and modular design make it a trusted solution for engineers and automation professionals aiming to enhance machine reliability and efficiency across a wide range of industrial applications.
