Installation & Setup Guidance
Proper installation is key to achieving optimal performance from the 330708-00-24-10-11-05. The probe uses a 5/8-18 UNF thread; ensure the mounting hole is clean and properly threaded. Apply the recommended torque of 15.2 N•m (133 in•lb) to avoid damaging the case or seal. For the ClickLoc connector, finger-tighten only—maximum torque is 0.565 N•m (5 in•lb). The minimum bend radius for the cable is 25.4 mm (1.0 in), so route cables carefully to avoid kinking. When installing, verify that the probe tip pressure seal is not compromised by excessive heat or cold below -34°C, which may cause premature failure.
Maintenance & Reliability
Bently Nevada 330708-00-24-10-11-05 proximity probes are built for long-term reliability, but periodic inspection is recommended. Check the connector for signs of wear or corrosion. Ensure the cable is not subject to repeated flexing beyond the minimum bend radius. The probe operates reliably across a wide temperature range, but avoid exposing it to temperatures below -34°C (30°F) for extended periods, as this can degrade the Viton seal. The AISI 304 stainless steel case and PPS tip resist most industrial contaminants, making the probe suitable for high-moisture or chemical environments. Regular calibration checks (per manufacturer guidelines) ensure continued accuracy.
Selection Guide & Purchasing Advice
Before purchasing the 330708-00-24-10-11-05, verify the following: the required thread type (5/8-18 UNF), overall cable length (1.0 metre in this model), and agency approval option (05 – Multiple Approvals). This probe does not include armor; if additional cable protection is needed, consider an armored variant. For applications requiring different lengths or thread options, consult the full 3300 XL series. UBEST Automation offers this genuine Bently Nevada probe with full traceability.
