This non-contact sensor is specifically designed to measure shaft vibration, axial position, and rotor displacement on critical rotating machinery. By utilizing eddy-current technology, it translates the physical distance between the probe tip and the target shaft into an electrical signal, enabling real-time condition monitoring and machinery protection in steam turbines, gas turbines, compressors, and high-pressure pumps.\u003c\/p\u003e\n\u003cp\u003eThis particular configuration features a \u003cstrong\u003e3\/8-24 UNF thread\u003c\/strong\u003e case \u003cstrong\u003ewithout armor\u003c\/strong\u003e, providing robust mounting in space-constrained industrial installations.
