Quick Detail

Description

The 330101-00-40-20-12-05 3300 XL 8 mm Proximity Probe is a high-performance eddy current transducer engineered for industrial automation, predictive maintenance, and machinery condition monitoring. This 3300 XL 8 mm probe generates a voltage output directly proportional to the distance between the probe tip and conductive surfaces, enabling both static position measurements and dynamic vibration analysis in rotating equipment. Designed for fluid-film bearings, turbines, compressors, and pumps, it ensures accurate monitoring in automated control systems.

Constructed with a 3/8-24 UNF threaded case with an overall length of 4.0 inches and paired with a 2.0-meter FluidLoc cable, the probe maintains mechanical and signal integrity while preventing fluid ingress. The Miniature coaxial ClickLoc connector provides secure, vibration-resistant connections, and the TipLoc and CableLoc design ensures up to 330 N pull strength, improving durability in automated machinery. The probe operates across extreme temperatures from -52°C to +177°C (-62°F to +350°F), with 50 Ω output resistance, 69.9 pF/m cable capacitance, and less than 2 mV/V supply sensitivity, ensuring stable and precise readings. Compliant with CSA, ATEX, and IECEx standards, the 3300 XL 8 mm probe also meets API 670 requirements for linearity, mechanical configuration, and temperature stability. Fully backward compatible with existing 3300 series probes, extension cables, and Proximitor sensors, it integrates seamlessly into automated monitoring networks.
