The required Failure Modes, Effects and Diagnostic Analysis (FMEDA) report provides safety instrumentation engineers with the necessary failure rates per IEC 61508 and with proof test recommendations. The series has an SIL 1 rating with a HFT (Hardware Fault Tolerance) of 0 or SIL 2 rating with a HFT of 1 or with proven-in-use demonstration according to IEC 61511 (type B subsystem). The two-wire radar transmitters include dual port technology, advanced surface tracking and condensation- and dirt-resistant antennas.
