This extension cable is engineered to maintain a characteristic impedance of 75 Ohm, which is required to minimize signal reflections that could otherwise result in erroneous gap voltage readings. Maintaining the electrical continuity of the coaxial path is essential for accurate rotor position and vibration data acquisition. When integrating these cables, verify that the total length—inclusive of the probe lead and extension cable—aligns with the system calibration requirements to ensure the output remains within the linear range of the -10 VDC target.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 330930-065-00-05 cable be field-terminated or shortened?\u003c\/p\u003e\n\u003cp\u003eA: No. Any modification to the coaxial cable length or connector assembly alters the electrical capacitance and resistance of the transducer system. This invalidates the factory calibration and leads to measurement errors.\u003c\/p\u003e\n\u003cp\u003eQ: How does cable length affect the gap voltage?\u003c\/p\u003e\n\u003cp\u003eA: The transducer chain is a matched system. Increasing the length adds capacitance, which can shift the operating point of the proximity sensor. Always verify the gap voltage at the monitor terminal after installation to ensure it stays within the required -10 VDC target.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRouting:\u003c\/strong\u003e Route the extension cable through dedicated conduit or instrument trays.
