Core Functional Features

1. 4-Channel Independent Axial Thrust Position Monitoring

   Equipped with 4 fully isolated monitoring channels, simultaneously measures multi-point rotor axial thrust displacement, differential expansion and axial dynamic movement status of large rotating machinery.

2. Professional Static & Dynamic Axial Signal Processing

   Separates and processes DC static axial gap position signal and AC dynamic axial vibration signal independently, accurately reflects rotor axial offset, thrust increase trend and axial vibration fault characteristics.

3. Fully Configurable Dual-Level Alarm Protection

   Supports independent setting of warning and danger alarm thresholds for each channel; supports programmable AND/OR voting interlock logic through 3500 configuration software, realizes accurate safety interlock protection.

4. Standard 4–20 mA Analog Signal Output

   Converts axial position data into standard industrial current loop signals, directly uploads data to DCS, PLC and central control room monitoring platforms.

5. Real-Time Status Visual Indication

   Front-panel digital display value, channel running indicator, warning alarm indicator and danger alarm indicator, intuitively reflects real-time monitoring status and abnormal faults on site.

6. Complete Fault Self-Diagnosis Function

   Automatically detects sensor disconnection, cable damage, channel open/short circuit and abnormal signal status, outputs safe defeat state and avoids false alarm and false interlock actions.

7. Ultra-Low Drift High Stability Performance

   Professional temperature compensation circuit, extremely low temperature drift, maintains stable accurate measurement data during long-term continuous operation.

8. Perfect 3500 System Seamless Integration

   Standard full-height plug-in structure, fully matches original 3500 system backplane communication logic, seamlessly connects with barrier modules, relay modules and communication modules.
