Quick Detail

Description

The 330101-00-18-20-12-05 3300 XL 8 mm Proximity Probe is a high-precision eddy current displacement sensor designed for advanced industrial automation and rotating machinery protection systems. This 3300 XL 8 mm Proximity Probe converts the distance between its sensing tip and a conductive target into a stable, proportional voltage signal, enabling accurate monitoring of both static shaft position and dynamic vibration. With a 2 mm (80 mils) linear range, the probe is ideally suited for fluid-film bearing machines used in automated power generation, oil and gas processing, petrochemical plants, and heavy industrial equipment.

The 330101-00-18-20-12-05 proximity probe features a compact 3/8-24 UNF threaded probe case, a 2.0 meter FluidLoc cable, and a Miniature coaxial ClickLoc connector that ensures secure and vibration-resistant electrical connections. Designed for harsh automation environments, the probe operates reliably across an extended temperature range of -52°C to +177°C while maintaining 50 ohm output resistance and supply sensitivity below 2 mV/V for excellent signal stability. The controlled 69.9 pF/m cable capacitance supports long-distance signal transmission without degradation. Certified with CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm Proximity Probe is suitable for hazardous-area automation applications where safety, accuracy, and long-term reliability are essential.
