Product Overview

The 330101-00-45-15-02-00 is a precision-engineered 8 mm proximity probe belonging to the industry-standard 3300 XL series. This transducer is designed to measure static (position) and dynamic (vibration) distances between the probe tip and a conductive target, such as a rotating shaft. As a critical component of Turbine Supervisory Instrumentation (TSI), it provides the essential data required for vibration monitoring, thrust position analysis, and eccentricity measurements in high-speed industrial machinery. The 3300 XL system is renowned for its cross-compatibility, allowing this probe to interface seamlessly with 3300 XL Proximitor sensors without requiring manual field calibration.

Key Functional Characteristics

The 3300 XL 8 mm probe is built to withstand the rigorous environments of steam turbines, gas turbines, and large-scale compressors. It utilizes a polyphenylene sulfide (PPS) tip that is overmolded onto the probe coil, providing a robust seal against moisture and oil penetration. The ClickLoc connector is designed with a gold-plated brass construction and a unique locking mechanism that prevents the connection from loosening due to machinery vibration. This specific 1.5-meter variant offers sufficient lead length for routing through internal machine housings to external junction boxes.

Application and Integration

This proximity sensor is a primary tool for predictive maintenance and machinery protection. Its main applications include:

• Continuous vibration monitoring of fluid-film bearing machines.

• Axial thrust position measurement for preventing catastrophic internal contact.

• Phase reference (Keyphasor) signal generation for speed and timing analysis.

• Integration into 3500 Series or 3300 Series monitoring racks via a compatible Proximitor.
