Quick Detail

Description

The 330101-33-53-10-12-05 3300 XL 8 mm Proximity Probe is a precision-engineered non-contact sensor designed to deliver highly reliable vibration and position measurement for critical rotating machinery operating in demanding industrial environments. As part of the proven 3300 XL 8 mm Proximity Probes family, this model is built to provide stable, repeatable performance across a wide range of mechanical and thermal conditions, making it an essential sensing element in machinery protection and condition monitoring systems.

Utilizing advanced eddy-current sensing technology, the 3300 XL 8 mm Proximity Probe generates a linear voltage output directly proportional to the distance between the probe tip and a conductive target. This enables accurate monitoring of radial vibration, axial position, and shaft displacement without physical contact, eliminating mechanical wear and ensuring long-term measurement stability. The probe is optimized for a 2 mm linear range, allowing precise detection of small positional changes that are critical for early fault identification in high-speed rotating equipment.

The 330101-33-53-10-12-05 configuration features a 3.3-inch unthreaded length and a compact 5.3-inch overall case length, making it well suited for installations with limited mounting space. The integrated 1.0-meter cable with a miniature coaxial ClickLoc connector ensures secure electrical connection and excellent signal integrity, even in high-vibration environments. This design simplifies installation and minimizes the risk of signal degradation caused by loose or improperly terminated connections.

Applications

The 330101-33-53-10-12-05 3300 XL 8 mm Proximity Probe is widely used for continuous radial vibration monitoring on general-purpose rotating machinery such as centrifugal pumps, industrial fans, and electric motors. Its non-contact measurement principle and stable linear output allow maintenance teams to detect imbalance, misalignment, and shaft instability at an early stage, supporting predictive maintenance strategies and reducing unplanned downtime.

In high-speed and high-temperature applications, including compressors, steam turbines, and gas turbine auxiliary equipment, the 3300 XL 8 mm Proximity Probe provides accurate axial position and shaft displacement measurements. The PPS probe tip and stainless steel housing ensure reliable operation in environments with elevated temperatures, oil exposure, and mechanical stress, helping operators maintain correct operating clearances and prevent thrust-related failures.

The probe is also well suited for installations in hazardous or regulated industrial environments such as petrochemical plants, power generation facilities, and offshore platforms. With CSA, ATEX, and IECEx approvals, the 330101-33-53-10-12-05 3300 XL 8 mm Proximity Probe can be safely deployed in classified areas while maintaining precise vibration and position monitoring performance under continuous operation.
