Quick Detail

Description

The 330104-00-05-10-01-00 3300 XL 8 mm Proximity Probes are high-precision eddy current sensors developed for continuous condition monitoring and machinery protection in critical industrial rotating equipment. As a core component within proximity transducer systems, the 3300 XL 8 mm Proximity Probes are designed to accurately measure the distance between the probe tip and a conductive target surface, converting mechanical motion into a stable and linear voltage signal suitable for vibration, position, and speed analysis.

Operating on a proven eddy current measurement principle, the 3300 XL 8 mm Proximity Probes provide instantaneous and proportional output corresponding to shaft movement. This capability enables reliable monitoring of radial vibration, axial (thrust) position, and Keyphasor reference signals in high-speed and high-load machinery. The defined 2 mm (80 mils) linear range ensures precise measurement resolution, allowing operators to detect subtle mechanical changes associated with imbalance, misalignment, bearing wear, or thermal growth at an early stage.

The mechanical construction of the 3300 XL 8 mm Proximity Probes emphasizes durability and long-term stability. The probe case is manufactured from AISI 303 or 304 stainless steel, offering strong resistance to corrosion, mechanical stress, and industrial contaminants. The probe tip is made of polyphenylene sulfide (PPS), a high-performance engineering material known for its excellent thermal stability and chemical resistance. This combination enables the 3300 XL 8 mm Proximity Probes to operate reliably in oil-laden, humid, or chemically aggressive environments commonly found in power generation, petrochemical processing, and heavy manufacturing.

Applications

1.Radial Vibration Monitoring of Rotating Machinery

The 3300 XL 8 mm Proximity Probes are widely used for continuous radial vibration monitoring in rotating equipment such as turbines, compressors, pumps, and large motors. By detecting minute changes in shaft position within the 2 mm linear range, the probes enable early identification of imbalance, misalignment, and bearing-related faults, supporting proactive maintenance strategies.

2.Axial Thrust Position Measurement

These probes provide accurate axial position measurement by maintaining a linear voltage output relative to shaft movement. This function is essential for monitoring thrust bearings and preventing excessive axial displacement that could lead to mechanical contact or catastrophic damage in power generation and process machinery.

3.Keyphasor Reference and Speed Detection

The 3300 XL 8 mm Proximity Probes are commonly applied as Keyphasor sensors, detecting shaft keyways or notches to generate precise phase reference signals. This capability supports rotational speed measurement, phase analysis, and balance correction in high-speed rotating machinery.

4.Critical Machinery Protection Systems

Due to their stable electrical performance and robust construction, the probes are integrated into machinery protection systems where continuous monitoring and alarm functions are required. They provide reliable input signals for vibration protection, shutdown logic, and condition-based maintenance systems in industrial plants.

Specifications

Competitive Advantage

1.Proven Measurement Accuracy and Signal Stability

The 3300 XL 8 mm Proximity Probes offer a defined 2 mm linear range, low supply sensitivity, and stable 50 Ω output resistance. These characteristics ensure consistent, low-noise signal output, enabling accurate vibration analysis and long-term trend monitoring even under fluctuating power and environmental conditions.

2.Robust Mechanical Design for Industrial Environments

Constructed with a stainless steel probe case and PPS probe tip, the probes exhibit strong resistance to corrosion, heat, oil, and mechanical stress. This durability extends service life, reduces replacement frequency, and lowers overall maintenance costs in demanding industrial applications.

3.Compact Structure for Flexible Installation

With a short 50 mm case length and zero unthreaded length, the 3300 XL 8 mm Proximity Probes can be installed in confined spaces without modifying existing machinery. The compact design allows precise probe positioning in tight bearing housings and compact machine layouts.

4.Seamless Integration into Monitoring Systems

Standardized electrical characteristics and connector design allow the probes to integrate smoothly into existing proximity transducer and monitoring systems. This simplifies system configuration, shortens installation time, and minimizes downtime during maintenance or probe replacement.
