The 330103-00-16-50-12-05 is an 8mm eddy current proximity probe, part of the Bently Nevada (a brand under Baker Hughes) 3300 XL series. As a core data acquisition component in large rotating machinery condition monitoring and protection systems, it is typically mounted securely near the hydrodynamic bearings of critical equipment such as industrial steam turbines, centrifugal compressors, and large fans. This probe is used for non-contact, precise measurement of rotor radial vibration, axial displacement, differential expansion, and critical phase velocity signals.
The 330103-00-16-50-12-05 probe is equipped with a ClickLoc miniature coaxial connector, and the cable has been upgraded to a FluidLoc leak-proof triaxial cable. This effectively prevents process lubricating oil from being drawn outwards through the cable core under internal pressure differential. The "-05" at the end indicates that the probe has obtained multiple hazardous area explosion-proof safety certifications from major global organizations such as ATEX, IECEx, and CSA.
In practical control systems, the front end of the 330103-00-16-50-12-05 is encapsulated in high-strength polyphenylene sulfide (PPS), capable of withstanding high-temperature corrosive environments from -52°C to +177°C immersion in lubricating oil, and can operate stably for extended periods. It must be used in conjunction with the 3300 XL proximity sensor, which utilizes the principle of high-frequency electromagnetic eddy currents to convert minute physical gap changes between the probe tip and the surface of the measured journal into a high signal-to-noise ratio voltage signal (standard sensitivity 7.87 V/mm).
