Designed for high-reliability industrial applications, this non-contact eddy-current sensor provides highly accurate displacement measurements, allowing operators to monitor shaft position and radial vibration in rotating machinery. By tracking the distance between the probe tip and a conductive metal target, it acts as a critical early warning sensor against machine wear, imbalance, or alignment faults.\u003c\/p\u003e\n\n\u003cp\u003eThis specific variant is configured with an unthreaded length of 0.0 inches (00 Option) and an overall case length of 7.7 inches (77 Option). This fully threaded, extended stainless steel body is ideal for deep-insertion mounting configurations in bearing housings or machine casings where a substantial threaded reach is required. It features a total cable length of 2.0 meters (20 Option) of standard unarmored coaxial cable terminated with a miniature ClickLoc connector (02 Option). This configuration is designed without agency approvals (00 Option), making it a highly cost-effective and dependable choice for general-purpose rotating machinery protection in non-hazardous industrial environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eStandard 8 mm probe tip diameter optimal for non-contact vibration and position measurements.\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-24 UNF-2A stainless steel body with 0.0 inches of unthreaded length and 7.7 inches of overall case length.\u003c\/li\u003e\n  \u003cli\u003eStandard 75 ohm coaxial cable with a total system length of 2.0 meters (6.6 feet) and no protective armor casing.\u003c\/li\u003e\n  \u003cli\u003ePremium miniature male ClickLoc coaxial connector for reliable and quick connection to extension cables.\u003c\/li\u003e\n  \u003cli\u003eRobust Viton O-ring seal embedded between the probe tip and the stainless steel case to resist pressure differentials.\u003c\/li\u003e\n  \u003cli\u003eNo agency approvals required, offering an economical sensor configuration for safe-area machine installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe Bently Nevada 330101-00-77-20-02-00 proximity probe is deployed extensively across heavy industries such as power generation, oil and gas, petrochemical, and water processing.
