The integrated coil in the probe tip is energized by a high-frequency RF signal from the associated Proximitor. This generates an electromagnetic field that penetrates the target shaft surface.\u003c\/p\u003e\n\u003cp\u003eAs the distance between the shaft (normally AISI 4140 steel) and the probe tip changes, the eddy-current losses alter the RF signal amplitude. The Proximitor demodulates this signal, converting the variation into a linear voltage output proportional to the physical gap. For 7200 Series 5 mm and 8 mm systems, a gap voltage validation is typically set to a center-range bias of approximately -10 VDC. This signal path provides high-resolution data for tracking sub-mil rotor dynamics, including radial vibration and axial thrust position without physical contact.\u003c\/p\u003e\n\u003ch3\u003eStandard Delivery Contents\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bently Nevada 21504-000-16-05-02 Proximity Probe (with 0.5 m integrated coaxial cable)\u003c\/li\u003e\n\u003cli\u003e1 x Miniature male coaxial connector (integrated on cable termination)\u003c\/li\u003e\n\u003cli\u003e2 x Standard hex mounting locknuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Mounting \u0026amp; Cable Routing Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLocknut Securement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThread the probe body into the tapped installation bracket and secure its physical position using the supplied hexagonal locknuts.
