摘要： A leak detection system (300) is described for detecting a leak through a closed valve disposed between an upstream pipe and a downstream pipe of an industrial process. An insertable plate (302) is coupled to the valve in the pipe in-line with the fluid flow. A sensor (316) couples to the flow and provides a signature output. A leak detector (324) is coupled to the sensor (16) and adapted to detect a leak through the valve based upon the signature output.

摘要： A field mountable dedicated process diagnostic device is used for diagnosing operation of an industrial control or monitoring system. An input is configured to receive at least one process signal related to operation of the industrial process. A memory contains diagnostic program instructions configured to implement a diagnostic algorithm using the process signal. The diagnostic algorithm is specific to the industrial process. A microprocessor performs the diagnostic program instructions and responsively diagnoses operation of the process based upon the process signal.
