Quick Detail

Description

The 330101-00-77-20-02-00 3300 XL 8 mm Proximity Probe is a precision eddy-current transducer designed for advanced industrial automation and condition monitoring systems. It delivers an output voltage directly proportional to the distance between the probe tip and the conductive target surface, allowing accurate static position and dynamic vibration measurements. With an overall case length of 7.7 inches and a 2.0-meter miniature coaxial ClickLoc cable, this probe ensures secure connectivity and robust performance in high-speed rotating machinery and automated monitoring systems.

The 3300 XL 8 mm probe operates reliably across extreme temperatures from -52°C to +177°C (-62°F to +350°F). It features a linear measurement range of 2 mm (80 mils), output resistance of 50 Ω, and supply sensitivity below 2 mV per volt, providing high-fidelity readings under fluctuating industrial power conditions. Enhanced structural integrity is achieved through TipLoc molding for a secure probe tip bond and CableLoc design delivering 330 N (75 lbf) pull strength. Optional FluidLoc cable protection prevents oil or other liquids from leaking through the probe, supporting safe and reliable automated operations. The probe is fully compatible with other 3300 series probes, extension cables, and Proximitor sensors, enabling fast replacement and maintenance without recalibration in automated systems.

Applications

1. High-Speed Turbine Vibration Monitoring
