Design and Develop of Functional Safety Temperature Transmitter for Fault Status

Abstract:

According to the requirements of the functional safety temperature transmitter high reliability, this paper selects the micro-power voltage reference, the reset monitor, the D-type flip-flop and the OR gate to design the functional safety temperature transmitter protection circuit for fault status. The protection circuit takes power from the data line of HART fieldbus by micro-power voltage references. According to the control signal of the functional safety transmitter, the protection circuit utilizes the state latch of D-type flip-flop, and realizes the functional safety temperature transmitter protection circuit for fault status.
