During installation, the gap voltage must be validated against the -10 VDC target midpoint to ensure linear operation. Proper alignment and gap adjustment are critical for accurate observation of rotor dynamics, including shaft centerline positioning and vibration magnitude. The system components, including the 3.6 metre probe and 6 metre extension cable, must be installed as a matched set to ensure measurement accuracy and maintain cross-talk suppression between adjacent sensor channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the total system length be modified in the field?\u003c\/p\u003e\n\u003cp\u003eA: No. The system is calibrated as a matched set consisting of the probe, extension cable, and Proximitor sensor. Field-modifying the 9.6 metre total length will alter the electrical impedance and introduce significant measurement errors.\u003c\/p\u003e\n\u003cp\u003eQ: What are the installation requirements for the cable?\u003c\/p\u003e\n\u003cp\u003eA: The minimum bend radius is 25.4 mm (1 inch). Avoid exceeding this limit to prevent damage to the internal coaxial conductors, which could result in signal attenuation or intermittent output.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Secure the probe in a rigid, non-conductive holder to prevent mechanical resonance.
