Quick Detail

Description

The 330101-00-20-20-12-05 3300 XL 8 mm Proximity Probe is a precision eddy current transducer specifically engineered for industrial automation and critical rotating machinery monitoring. This 3300 XL 8 mm Proximity Probe converts the distance between its probe tip and a conductive target into a proportional voltage signal, providing accurate measurements of both static shaft position and dynamic vibration. With a 2 mm (80 mils) linear range, it is designed for fluid-film bearing machines, compressors, turbines, pumps, and other automated industrial equipment where high reliability, precision, and safety compliance are essential.

The 330101-00-20-20-12-05 probe features a 3/8-24 UNF threaded stainless steel case, a 2.0 meter FluidLoc cable, and a Miniature coaxial ClickLoc connector that ensures secure, vibration-resistant electrical connections. Its patented FluidLoc cable technology prevents process fluids or oil from entering the cable core, maintaining signal integrity and reducing maintenance requirements. The probe operates over a wide temperature range of -52°C to +177°C (-62°F to +350°F), with 50 Ω output resistance, less than 2 mV/V supply sensitivity, and typical 69.9 pF/m extension cable capacitance for long-distance signal stability. Certified with CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm Proximity Probe is ideal for hazardous-area automation systems and ensures compliance in global industrial applications.
