The probe, model 330130-085-12-05, is a standard 8mm eddy current displacement sensor probe from the 3300 XL series manufactured by Bently Nevada.
As a core front-end component of critical industrial rotating machinery protection systems, the 330130-085-12-05 employs a non-contact measurement principle, enabling precise and continuous monitoring of shaft vibration, axial displacement, key phase quantities, and rotational speed in large equipment such as centrifugal compressors, steam turbines, and large water pumps, thus achieving online monitoring of equipment health.
The 330130-085-12-05 features a front-mounted design and is equipped with a 3/8-24 UNF imperial thread interface. Its configurations include Option 085 (representing 8.5 inches of unthreaded length) and Option 12 (representing 1.2 inches of total housing length; note: in special nested or bidirectional extension customizations, the ratio of total length to unthreaded length is specifically designed based on the penetration depth of the particular housing), and it comes with a standard ClickLoc miniature coaxial connector.
