The process fluid pressure transmitter which detects pressure transient phenomenon

摘要

The process fluid pressure transmitter (300), the process fluid pressure sensor (302), the measurement circuit (304), the controller (308), and the loop transmitter (316) it includes. The process fluid pressure sensor (302), it possesses the electric quality which fluctuates attendant upon process fluid pressure. The pressure sensor (302), it is connection possible in process fluid pressure source. The measurement circuit (304), the process fluid pressure sensor (302) it connects, and the process fluid pressure sensor (302) it offers the signal which shows electric quality. The controller (308) the measurement circuit (306) it connects, and receives the signal, it calculates process fluid pressure and at least on the basis of the portion of the signal. In addition as for the controller, it detects process fluid pressure transient phenomenon, as and, at least retained one regarding process fluid pressure transient phenomenon variable, it is constituted. The loop transmitter (316) the controller (308) it connects, in order the process communication loop (314) to offer the signal on, and, on the basis of process fluid pressure it is constituted. In addition the process fluid pressure transmitter (300), in order to offer the indication regarding the variable where one is retained at least, it is constituted.
