Operating as a core component of a non-contacting eddy current sensor system, this probe delivers reliable shaft vibration, position, and speed feedback for turbomachinery diagnostics. This specific model features a 3\/8-24 UNF threaded body, integrated stainless steel fluid-tight armor, a 2.0-inch unthreaded length, a 7.3-inch overall case length, a 0.5-meter total cable length, and standard ClickLoc miniature coaxial connectors. Designed with specialized agency approvals for specific regional environments, it ensures exceptional longevity and resistance to aggressive industrial lubricants and harsh chemical environments.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
