3300 XL 8 mm

3300 XL 8 mm Proximity Transducer System

The 3300 XL 8 mm Proximity Transducer System is designed for precise measurement of vibration, position, and speed in fluid-film bearing machines. The system offers top performance and full compliance with API 670 standards, ensuring accuracy, reliability, and stability.

System Components

• 3300 XL 8 mm Probe
• 3300 XL Extension Cable
• 3300 XL Proximitor Sensor

The system produces an output voltage that is directly proportional to the gap between the probe tip and the observed conductive surface, enabling accurate monitoring of both static and dynamic values. The system is ideal for the following applications:

• Vibration and Position Measurements on fluid-film bearings.
• Keyphasor Reference and Speed Measurements.

Key Features

• Advanced Performance: The 3300 XL 8 mm system represents the leading edge in eddy current proximity transducer technology.
• API 670 Compliance: The standard 3300 XL 8 mm 5-meter system meets API 670 standards for mechanical design, linear range, accuracy, and temperature stability.
• Full Interchangeability: The system components (probes, cables, sensors) are fully interchangeable, eliminating the need for component matching or bench calibration.
• Backward Compatibility: Compatible with non-XL 3300 series 5 mm and 8 mm transducer components. This includes the 3300 5 mm Probe, ideal for applications where space is limited.
