Core Functional Features
- API 670 Certified High Linear Accuracy
Maintains constant sensitivity and linearity across full detection range; fully meets international precision requirements for large heavy-duty rotating machinery protection monitoring.
- 12mm Large Tip Optimized Measurement Performance
12mm probe tip provides larger effective detection area, higher signal stability, lower lateral sensitivity error and wider linear range than 8mm/11mm probes; specially suitable for large-diameter heavy rotating shafts.
- 120mm Long-Stem Deep Installation Structure
Extended 120mm probe body length perfectly adapts to deep bearing box mounting holes and deep internal installation environments that short-stem probes cannot match.
- Patented Anti-Vibration Mechanical Design
TipLoc integrated molding probe tip + CableLoc reinforced cable connection; completely prevents cable fracture, signal looseness and measurement drift under high vibration industrial conditions.
- Complete Non-Contact Measurement
Zero mechanical wear, zero friction loss; supports full 24/7 continuous monitoring of shaft dynamic vibration and static displacement parameters.
- Superior Signal Anti-Interference Performance
Double-shielded coaxial cable fully isolates industrial electromagnetic noise; ensures complete signal integrity in high-voltage, high-power motor harsh industrial environments.
- Full System Interchangeability & Compatibility
Directly matches all 3300 XL series proximitors, 3500 machinery protection systems, FieldMonitor I/O monitoring modules; no individual calibration required for probe, cable and proximitor replacement.
- Plug-and-Play Easy Installation
ClickLoc quick-lock connector realizes fast finger-tight mounting with clear locking feedback; standard metric M14×1.5 thread adapts to universal heavy machinery mounting holes.
