To ensure accuracy in rotor dynamics analysis, the gap voltage must be validated at the Proximitor sensor output during commissioning. A nominal target of -10 VDC at the linear center of the probe range is required. To maintain signal integrity and prevent data corruption, cross-talk suppression must be implemented by routing transducer cables in dedicated metallic conduit, isolated from high-frequency electromagnetic interference and switching power circuits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 330703 11 mm probe be utilized in place of an 8 mm probe?\u003c\/p\u003e\n\u003cp\u003eA: No. The probe tip geometry and coil inductance are specifically matched to the associated Proximitor sensor. Substituting probe diameters without replacing the corresponding Proximitor will result in incorrect scale factors and non-linear measurement output.\u003c\/p\u003e\n\u003cp\u003eQ: Is field-shortening of the 1.0 m integral cable permitted?\u003c\/p\u003e\n\u003cp\u003eA: No. The assembly is factory-calibrated as a complete loop. Modifying the cable length alters the electrical capacitance and characteristic impedance of the system, which invalidates the calibration and compromises measurement precision.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting\u003c\/strong\u003e: Thread the M14 x 1.5 probe body into the mounting bracket until the required gap is achieved.
