Utilizes a laser-welded, oil-free ceramic diaphragm for high overpressure resistance (up to 500% of URL) and immunity to hydrogen embrittlement.
Temperature compensation via integrated Pt1000 RTD ensures accuracy across -50°C to +200°C.
Predictive Diagnostics:
Monitors sensor health, process anomalies (e.g., plugging, cavitation), and environmental stress (vibration, temperature).
Generates alerts for drift exceeding ±1% or potential failures, enabling predictive maintenance.

3.2 User-Centric Configuration
Local Operator Interface (LOI):
Full-color 3.5" touchscreen with multilingual support (English, Chinese, Arabic, etc.).
Guided setup wizards for zero/span calibration, unit conversion, and alarm thresholds.
