Features:
- 3300 XL Proximitor Sensor
- 3300 XL 8 mm Proximity Transducer System
- The 3300 XL probe and extension cable also reflect improvements over previous designs
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable4 with other nonXL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.
The 330180-12-05 Bently Nevada 3300 XL Proximitor Sensor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 3300 XL 8 mm system is our most advanced eddy current proximity sensor system. The standard 3300 XL 8 mm 5-meter system fully complies with American Petroleum Institute (API) 670 standards, meeting requirements in terms of mechanical construction, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity sensor systems achieve this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need for individual component matching or bench calibration.
This sensor is primarily used for monitoring the following high-speed rotating equipment:
Vibration Monitoring: Measuring dynamic radial vibration of the shaft in hydrodynamic bearing machinery (e.g., turbines, compressors, and pumps).
Axial Position (Thrust): Tracking the static axial position of the rotor to detect excessive wear or potential contact between rotating and stationary components.
Velocity and Key Phasor Signals: Providing high-frequency phase references (key phasors) and velocity measurements for machine diagnostics and protection systems.
Safety-Critical Controls: Typically integrated into 3500 monitoring systems for overspeed protection and machinery protection compliant with SIL 2 or SIL 3 safety standards.
