Functional Features
- Signal Auto-Adaptation: Automatically identifies thermocouples, RTDs, voltage, and current signals.
- Non-Linear Compensation: Built-in 32-segment compensation curves for precise sensor correction.
- Fault Diagnostics: Real-time monitoring for open circuit, short circuit, and over-range alarms.
- High Anti-Interference: Effectively suppresses common-mode interference in high-temperature, high-vibration environments.
Application Scenarios
Widely applied in petrochemical (e.g., FCC units), power energy, and metallurgical manufacturing (e.g., rolling mill lines) where extreme precision and stability are required.
Performance Parameters
- Measurement Accuracy: Up to ±0.1% for temperature, ±0.3% for force.
- Environmental Adaptability: Class G3 harsh environment design.
Material Composition
High-reliability industrial-grade electronic components with a robust enclosure structure.
Structural Characteristics
- Modular Design: Integrates signal input, conditioning, isolation amplification, and linearization.
- Compact Form Factor: Saves control cabinet space.
Working Principle
Receives weak analog signals from sensors, converts them to high-precision digital signals via Σ-Δ ADC, applies non-linear compensation and filtering, and transmits to the DCS.
Installation Requirements
- Ensure correct connection of isolated grounds.
- Use shielded twisted-pair cables for signal lines, routed away from strong interference sources.
Precautions for Use
- Verify communication loop impedance when configuring HART parameters.
- Periodically check TA component tightness to prevent vibration-induced contact issues.
