Proper impedance matching ensures predictable linear displacement conversion across the entirety of the probe dynamic measuring range.\u003c\/p\u003e\n\u003cp\u003eDuring loop commissioning, field personnel perform gap voltage validation across the signal terminals to verify a target reading of approximately -10 VDC at the mechanical center position. The coaxial outer shield combined with proper physical conduit routing provides cross-talk suppression and isolates high-frequency raw vibration signals from external electromagnetic interference (EMI).\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can an 8.0 m extension cable be interchanged with a 4.0 m extension cable without recalibrating the Proximitor sensor?\u003c\/p\u003e\n\u003cp\u003eA: No. A 3300 XL Proximitor sensor is calibrated to a specific total system length (typically 5.0 m or 9.0 m). Replacing an 8.0 m cable with a different length alters the system capacitance, invalidating factory calibration curves and introducing displacement errors.\u003c\/p\u003e\n\u003cp\u003eQ: Is the 330730-080-00-00 extension cable suitable for continuous immersion in liquids?\u003c\/p\u003e\n\u003cp\u003eA: No. While the cable assembly features hermetically-sealed connector housings rated for up to 100% relative humidity, it is specified as non-submerged. Continuous liquid immersion requires liquid-tight protective conduit and sealed outer junction fittings.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the cable outer FEP jacket and ClickLock coaxial connectors for cuts, pin contamination, or bending prior to installation.\u003c\/li\u003e\n\u003cli\u003ePull the cable through dedicated electrical conduits or metal raceways, ensuring the minimum static bend radius of 25.4 mm (1.0 in) is preserved along the entire run.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum separation distance of 300 mm between the extension cable routing and high-voltage AC power lines or variable frequency drive (VFD) outputs.\u003c\/li\u003e\n\u003cli\u003eAlign the coaxial ClickLock connectors, press until fully engaged, and secure hand-tight plus 1\/8 turn.
