3. Core Functional Features
3.1 Advanced Sensor Technology
Single-Crystal Silicon Sensor:
Utilizes monocrystalline silicon with piezoresistive properties for high linearity and minimal hysteresis.
Laser-trimmed circuitry compensates for temperature effects, ensuring accuracy across the operating range.
Overpressure Protection:
Withstands up to 400% of URL without damage (e.g., 0-100 bar sensor handles 400 bar overload).
3.2 User-Centric Configuration
Local Operator Interface (LOI):
Integrated LCD display with tactile buttons for on-site configuration without external tools.
Displays real-time pressure values, diagnostics, and unit conversion (bar, psi, kPa).
Quick Calibration:
One-button zero/span adjustment via HART® or Bluetooth, reducing downtime during maintenance.
3.3 Diagnostic and Predictive Maintenance
Self-Diagnostics:
Monitors sensor health, cable breaks, and process anomalies (e.g., overpressure, temperature extremes).
Generates alerts for drift exceeding ±2% or communication failures.
Siemens MindSphere Integration:
Transmits data to Siemens IoT platform for predictive analytics, enabling condition-based maintenance.
3.4 Flexible Communication
Multi-Protocol Support:
PROFIBUS PA: Ideal for integration with Siemens PLCs (e.g., SIMATIC S7-1500) in factory automation.
Foundation Fieldbus: Suited for process industries requiring digital fieldbus networks.
Wireless Connectivity:
Bluetooth 5.0 enables configuration via mobile devices up to 30 meters away, enhancing safety in hazardous areas.
3.5 Customization Options
