Core Functional Features
- 14 mm Large Diameter High-Stability Measurement
14 mm probe diameter delivers larger detection area, stronger anti-interference ability, lower signal noise and higher linear stability than 8mm/11mm probes, perfectly suitable for large heavy high-temperature rotor shaft monitoring.
- Professional Extreme High-Temperature Resistant Design
Special high-temperature tip material supports continuous 260°C high-temperature operation, solves measurement failure problems of ordinary probes in high-temperature steam turbine and hot compressor environments.
- Long 10m Integrated Fixed Cable Structure
10 meters built-in integrated cable meets long-distance on-site wiring requirements; integrated probe and cable molding eliminates intermediate connectors, reduces signal attenuation and fault points, greatly improves overall system long-term reliability.
- Simultaneous Static & Dynamic Multi-Parameter Monitoring
Independently outputs DC axial thrust position gap signal and AC radial vibration dynamic signal, realizes synchronous monitoring of shaft axial displacement, rotor vibration, eccentricity and Keyphasor speed.
- Ultra-Low Temperature Drift High Precision Performance
Professional temperature compensation circuit, extremely low temperature drift coefficient, maintains stable accurate measurement data under drastic high-temperature environment changes.
- Patented ClickLoc™ Reliable Locking Connector
Gold-plated positive locking coaxial connector, tool-free quick plug/unplug, low signal loss, stable connection under strong high-temperature vibration conditions.
- Full Robust Harsh Environment Adaptability
Full stainless steel body, high-temperature resistant cable, IP67 protection, resistant to high temperature, oil mist, corrosion, dust and moisture.
- Full API 670 Safety Compliance & System Compatibility
Meets global machinery protection safety standards, direct plug-and-play matching with original 3300 XL proximitors, 3300/3500 systems, no additional on-site calibration required after installation.
