Sensor Technology
Hydrostatic Pressure Sensing: Ceramic or monocrystalline silicon diaphragm with laser-trimmed circuitry for minimal hysteresis.
Overpressure Protection: Withstands 400% of URL (e.g., 0-100 bar sensor handles 400 bar overload).
3. Design & Functional Features
Hardware Robustness
Process Seals: Options include Kalrez (high-temperature) or PTFE (chemical resistance).
Diaphragm Options: Front-flush, flush-mounted, or remote seals for viscous/contaminated media.
Dual-Chamber Housing: Isolates electronics from process connections, enhancing durability in corrosive environments.
User-Centric Operation
Local Operator Interface (LOI): Integrated LCD with tactile buttons for zero/span calibration, unit conversion (bar, psi, kPa), and diagnostics .
Quick Calibration: One-button adjustment via HART® or Bluetooth (optional).
Advanced Diagnostics
Self-Monitoring: Detects sensor drift, cable faults, and process anomalies (e.g., overpressure, temperature deviations).
NAMUR NE107 Compliance: Classifies faults into four categories (failure, maintenance required, check function, out-of-spec).
Predictive Maintenance: Logs 90 days of process data to forecast failures.
