Ensure the total electrical length of the probe and extension cable matches the calibration of the Proximitor (typically 5-meter or 9-meter system calibrations). Mixing unmatched cable lengths will distort the scale factor (e.g., standard 7.87 V\/mm or 200 mV\/mil) and introduce significant measurement errors into the TSI (Turbine Supervisory Instrumentation) system.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eCross-talk can occur if multiple proximity probes are mounted too close to one another without adequate physical separation. Maintain a minimum distance of at least three probe tip diameters between adjacent probes to prevent electromagnetic interference between the high-frequency RF carrier signals.
