The high-temperature PFA insulation and FluidLoc internal barrier design prevent oil and process fluids from wicking along the conductor core, protecting signal purity in high-temperature turbomachinery housings.\u003c\/p\u003e\n\u003cp\u003eDuring system setup, gap voltage validation requires verifying the baseline DC voltage (-10 VDC nominal target at static shaft center) at the Proximitor output terminals. Controlled capacitance parameters prevent oscillator frequency drift, maintaining accurate phase tracking during severe rotor dynamics events and ensuring high channel-to-channel cross-talk suppression.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 330854-080-24-CN extension cable be trimmed or modified in the field to match exact conduit lengths?\u003c\/p\u003e\n\u003cp\u003eA: No. Trimming or splicing alters the total electrical capacitance and resistance of the 8.0 m transmission path. This shifts the Proximitor tuning curve, invalidates factory calibration, and causes severe scale factor errors during gap voltage validation.\u003c\/p\u003e\n\u003cp\u003eQ: What physical protection does the High-Temperature FluidLoc cable option (Option 24) provide?\u003c\/p\u003e\n\u003cp\u003eA: The FluidLoc cable construction includes an internal fluid barrier combined with PFA insulation rated up to +200 deg C. It stops hot synthetic oils, steam, and liquid hydrocarbons from migrating inside the cable jacket into terminal enclosures.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eInspect the PFA jacket and miniature coaxial connectors for contamination, pin damage, or physical abrasions prior to routing.\u003c\/li\u003e\n\u003cli\u003eRoute the cable through dedicated metallic conduit or wireways, keeping a minimum static bend radius of 25.4 mm (1.0 in).\u003c\/li\u003e\n\u003cli\u003eMaintain at least 300 mm clearance between the extension cable run and high-voltage AC power lines or VFD motor cables to eliminate inductive noise.\u003c\/li\u003e\n\u003cli\u003eAlign the coaxial connectors, push firmly until the latching mechanism engages, and slide a protective connector boot over the interface junction.\u003c\/li\u003e\n\u003cli\u003ePerform gap voltage validation across the Proximitor output terminals using a calibrated digital multimeter; confirm the DC voltage matches the static target (typically -10 VDC).\u003c\/li\u003e\n\u003cli\u003eConnect the cable shield to instrument ground exclusively at the Proximitor panel end.
