- 330194 3300 XL 8 mm Probe, M10 x 1 thread,with armor
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 330194-00-07-10-05 Bently Nevada 3300 XL 8 mm ETR Proximity Probes 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.
- The ETR series is designed for areas exceeding the standard 177°C (350°F) temperature limit:
- Steam Turbine Monitoring: Measures radial vibration and axial (thrust) position at the "hot end" of a steam turbine.
- Extreme High-Temperature Environments: Operates continuously at temperatures up to 218°C (425°F), with cables capable of withstanding higher intermittent peak temperatures.
- Gas Turbine Exhaust Areas: Tracks shaft movement near the exhaust casing (where heat radiation is intense).
- Hazardous Area Operations: ATEX/IECEx certified for use in the explosive environments common in refineries and chemical plants.
