- Metric‑thread‑structure enables direct screwing‑in installation into machine‑housing tapped mounting‑hole Working Principle: Proximitor sensor provides high‑frequency excitation signal to probe‑internal coil, generating alternating‑electromagnetic‑field distribution around probe tip. Eddy‑current effect occurs on surface of nearby conductive rotating‑shaft target. Variation of physical gap changes eddy‑current energy‑consumption level, further altering probe‑coil equivalent‑impedance value. Proximitor internal‑circuit converts impedance‑variation into DC‑voltage‑output‑signal which linearly reflects gap‑distance value, delivering static‑position and dynamic‑vibration‑waveform‑data to upper‑level monitoring‑system. Installation Requirements:
- Keep probe tip strictly perpendicular to rotating‑shaft target‑surface, angular‑deviation shall be less than 1‑degree
- Screw probe body into M10 × 1 tapped‑hole on bearing‑housing, avoid over‑torque damage to thread‑structure
- Adjust static‑working‑gap to factory‑recommended 1.27 mm before equipment startup
- Connect ClickLoc‑connector by finger‑tight rotation until audible click‑locking‑feedback, install connector‑protector in correct position
- Sum of probe‑cable‑length and extension‑cable‑length must match Proximitor nominal‑calibrated total‑system‑length
- Ensure mechanical‑clearance between probe‑tip and rotating‑shaft‑surface to eliminate collision‑risk
- Separate proximity‑probe‑signal‑cable from high‑voltage‑power‑cables with minimum 150 mm physical‑clearance
- Secure probe‑cable with cable‑clamps to eliminate pulling‑tension transferred onto probe‑housing Usage Notes:
- Strictly avoid mechanical‑impact, scratch and abrasion‑damage on probe‑tip polymer‑surface
- Do not cut or shorten factory‑integrated probe‑cable at installation‑site
- Only use original 3300‑XL‑series matched extension‑cable and Proximitor‑sensor
- Periodically inspect connector‑protector fastening‑status under heavy‑vibration cabinet‑environment
- Prevent machine‑oil, water‑vapor and corrosive‑gas invading connector‑contact‑pin‑region
- Execute gap‑voltage‑reading‑check during each‑unit‑overhaul‑cycle to validate full‑transducer‑loop‑health‑status
