Its 8 mm probe tip provides thicker encapsulation for greater robustness, making it suitable for applications where physical abuse is a concern. The 5-meter cable length is optimized for use with the 5-meter Proximitor sensor, ensuring accurate readings. In petrochemical and power generation plants, this probe helps detect early signs of bearing wear or imbalance, reducing unplanned downtime.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\u003cp\u003eInstalling the 330191-00-40-50-CN requires careful attention to thread engagement and torque. Use the 3\/8-24 UNF thread with a maximum engagement of 0.563 inches to avoid damaging the probe. Tighten the connector to 0.565 N·m (5 in·lbf) using a calibrated torque wrench. Ensure the probe cable is routed without sharp bends and secured to prevent strain. For differential pressure sealing, the Viton® O-ring must be properly seated. One-meter systems do not require an extension cable, but for 5-meter probes, use only the corresponding 5-meter Proximitor sensor.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eRegular inspection of the probe tip and cable is recommended. The patented CableLoc design provides 330 N pull strength, but avoid exceeding this load. Check the gold-plated connectors for oxidation every six months. The probe's PPS tip resists chemical degradation, but in aggressive environments, consider the optional FluidLoc cable to prevent oil leakage. The 330191-00-40-50-CN is not pressure tested prior to shipment, so verify sealing after installation. To maximize service life, operate within the specified temperature envelope (-55°C to +232°C for T1 classification).\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering, confirm that the 330191-00-40-50-CN matches your system requirements: 5.0 m total length, without armor, and CN country-specific approval. Ensure compatibility with Bently Nevada Proximitor sensors and extension cables. For replacements, verify the thread size and overall length against the existing probe.
