The 3300 XL 8 mm Proximity Transducer System consists of:

 One 3300 XL 8 mm probe,

 One 3300 XL extension cable1, and

 One 3300 XL Proximitor* Sensor2.

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 measurements3.

The 3300 XL 8 mm system delivers the most advanced performance in our eddy 

current proximity transducer systems. The standard 3300 XL 8 mm 5-metre 

system also fully complies with the American Petroleum Institute’s (API) 670 

Standard (4th Edition) for mechanical configuration, linear range, accuracy, and 

temperature stability. All 3300 XL 8 mm proximity transducer systems provide 

this level of performance and support complete interchangeability of probes, 

extension cables, and Proximitor sensors, eliminating the need to match or 

bench calibrate individual components.

Each 3300 XL 8 mm Transducer System component is backward-compatible and 

interchangeable4 with other non-XL 3300 series 5 mm and 8 mm transducer 

system components5. This compatibility includes the 3300 5 mm probe, for 

applications in which an 8 mm probe is too large for the available mounting 

space6,7.
