By combining the sensing probe and signal conditioning electronics into a single, factory-sealed enclosure, this unit addresses the requirement for compact, reliable vibration and displacement measurement in high-speed turbomachinery. This integrated architecture removes the need for separate Proximitor sensors and extension cables, thereby reducing the total footprint of the monitoring instrumentation and minimizing the potential for connection-related signal failures in high-vibration zones.\u003c\/p\u003e\n\u003cp\u003eThe transducer utilizes eddy-current induction to provide high-resolution displacement data. During system commissioning, it requires precise mechanical gap setting to achieve the mandatory -10 VDC output setpoint at the monitor input. The internal circuitry is engineered to preserve signal linearity and suppress cross-talk in multi-channel TSI (Turbine Supervisory Instrumentation) racks. This assembly is suited for environments where space is limited and structural integrity is required to sustain accurate data acquisition across the full frequency response range of the monitored asset.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr
