Design of Functional Safety Temperature Transmitter and Reliability Analysis

Abstract:

This paper presents the design of the functional safety temperature transmitter and reliability analysis to develop the certified safety related product with independent intellectual property rights. According to the functional safety standard IEC61508 and the 1-out-of-1 and Diagnosis (1oo1D) architecture of the temperature transmitter, self-diagnostic methods are proposed. At the same time a Markov model is established to assess the reliability of the transmitter quantitatively. Analysis results show that safety integrity level (SIL) is SIL2 and safety temperature transmitter complies with functional safety requirements and safety integrity level requirements.
