Bently Nevada 330102-00-25-05-02-00 | 3300 XL 8mm Threaded Proximity Probe

The Bently Nevada 330102-00-25-05-02-00 is a high-precision 3300 XL 8mm threaded eddy-current proximity probe, a core model in Bently Nevada’s industrial non-contact transducer series. Different from the threadless 330101 probe series, this 330102 variant features an integrated threaded probe body for direct screw-in installation, delivering ultra-stable positioning for machinery vibration and displacement monitoring. Designed for critical rotating equipment including steam turbines, centrifugal compressors and generators, it accurately measures shaft radial vibration, axial thrust position and rotor eccentricity via high-frequency eddy-current induction technology. Equipped with a 25-meter factory molded integral cable and standard linear range configuration, it offers excellent on-site adaptability for large-span equipment layout and long-distance cabinet wiring. Fully compatible with 3300 XL proximitor sensors and 3500 series TSI machinery protection systems, it is widely adopted in power, petrochemical and heavy industrial safety monitoring projects.

4. Core Product Advantages

The 330102-00-25-05-02-00 threaded probe solves the positioning instability problem of threadless probes, featuring integrated thread structure for direct and fast installation with high positioning accuracy and strong anti-vibration capability. Adopting standard 0–2mm linear range and industry-unified 7.87V/mm sensitivity, it delivers highly consistent and repeatable measurement data, fully matching mainstream TSI system calibration standards. Equipped with a 25-meter factory one-piece cable, it eliminates on-site cable welding and intermediate joint faults, greatly improving signal transmission stability and construction efficiency.

With non-contact eddy-current measurement principle, the probe has no mechanical friction loss and ultra-long service life, suitable for long-term 7×24-hour online monitoring. The fully sealed stainless steel body and multi-layer shielding design resist dust, oil pollution and strong electromagnetic interference on industrial sites. Standard industrial certification and API 670 compliance ensure reliable operation in conventional and hazardous explosive environments. Compared with short-cable probes, the 25-meter ultra-long cable adapts to large-span equipment layout and remote cabinet installation, with wider on-site applicability.

5. Industrial Application Scenarios

This threaded long-cable proximity probe is widely used for fixed-point precision monitoring of core rotating machinery in large industrial sites. In thermal power plants, it is applied to steam turbine shaft vibration, thrust bearing displacement and rotor swing monitoring, providing stable and accurate data support for unit TSI protection systems. In petrochemical and natural gas industries, it monitors high-speed centrifugal compressors, turbo-expanders and process pressurization equipment, adapting to remote cabinet wiring layout of large petrochemical units. It is also suitable for generator sets, large industrial pumps and blower equipment monitoring, perfectly fitting scenarios requiring fixed thread installation and ultra-long-distance signal transmission, effectively improving the overall stability and accuracy of machinery safety monitoring systems.
