NAMUR NE43 Fault Detector

Monitor analog loop currents and flag sensor calibration faults based on standard NAMUR NE43 guidelines.

Purpose & Calculation Breakdown (India)

Purpose of this Tool: Categorize current signals to identify physical open loop wires (low fault) or short circuit issues (high fault) using standard diagnostic limits.

• NAMUR NE43 Low Failure Threshold:I_{mA} \le 3.60\ \text{mA} \to \text{Critical Sensor Fault (Low)}
• NAMUR NE43 High Failure Threshold:I_{mA} \ge 21.00\ \text{mA} \to \text{Critical Sensor Fault (High)}
• Normal Operating Current Span:3.80\ \text{mA} \le I_{mA} \le 20.50\ \text{mA} \to \text{Measurement Active}
