Core Functional Features
- Dual Independent Redundant Thrust Position Monitoring
Two fully isolated channels realize redundant mutual verification monitoring of rotor axial thrust position; greatly improves monitoring reliability and avoids single-point fault failure.
- Ultra-High Precision Axial Displacement Measurement
0.1 μm high measurement resolution, matches API 670 precision requirements; accurately captures tiny axial drift, thrust offset and rotor movement state.
- Multi-Level Configurable Alarm & Trip Protection Logic
Independent adjustable alarm 1 (warning), alarm 2 (pre-danger) and danger trip protection limits for each channel; supports latching/non-latching trip mode selection to meet different machinery safety interlock requirements.
- Low-Frequency Specialized Signal Filtering
DC–1 kHz bandwidth optimized for slow-changing axial thrust displacement; effectively filters high-frequency radial vibration noise and improves axial position measurement accuracy.
- Complete Real-Time Self-Diagnosis Function
Automatic detection of probe disconnection, cable short circuit, transducer fault and signal loss; immediately outputs fault alarm to system rack and upper monitoring platform.
- Full Galvanic Isolation Design
Electrical isolation between sensor input, module circuit and system backplane; isolates industrial electromagnetic interference and ensures long-term signal stability.
- Hot-Swappable & Fully Interchangeable Structure
Standard 3500 half-slot design, plug-and-play hot swap; fully compatible with all 3500 system racks and backplanes, no field recalibration required for replacement.
- Perfect System Integration Compatibility
Seamlessly matches 3500/15 power modules, 3500/33 Keyphasor modules, 3500/22 vibration modules and system display/relay output modules.
