This paper introduced configuration and software design of a safety valve on-line monitoring system on the basis of the introduction about structure design of safety valve core sensor. Some key technology adopted during the process of designing and developing the data acquisition system that based on VC＋＋6.0 was analyzed. Through research of correlation testing, the system proved it ran well with stability and veracity. The results showed that, Compared to the standard transducer, the safety valve sensor had more accurate testing value, depicted the opening process of safety valve more particularly, the fidelity of testing value is better.
