Core Functional Features

1. Dedicated Axial Thrust Position Monitoring Design

   Optimized signal conditioning algorithm for shaft axial displacement and thrust movement monitoring, accurately reflecting shaft axial drift, thrust bearing wear and abnormal thrust load conditions.

2. Integrated Proximitor Architecture

   Built-in complete proximity signal conditioning circuit, no external proximitor module required, greatly simplifies on-site wiring and installation.

3. Complete Fault Safety Protection Circuits

   Equipped with Not OK / Signal Defeat circuit, automatically locks output and prevents false high alarms when probe damage, cable breakage or loose connection occurs. Built-in power-up inhibit circuit eliminates signal distortion caused by power supply voltage transients.

4. Independent Zero & Span Adjustment

   Non-interacting zero and span potentiometers support on-site loop signal calibration and range fine-tuning.

5. Built-in Test Input Terminal

   Supports quick loop output verification with external signal generator without disassembling on-site wiring.

6. Dual Signal Output Mode

   Provides standard 4–20 mA control loop output for system interlock protection, and independent dynamic diagnostic signal output for advanced fault analysis.

7. Ultra-High Environmental Adaptability

   Fully potted sealed structure, resistant to high humidity, dust, oil mist and corrosion, suitable for long-term unattended operation.

8. Compact & Flexible Deployment

   Ultra-small size, adapts to narrow installation space of small and medium rotating machinery, supports direct OEM matching and retrofitting reconstruction.
