DIAGNOSTIC SYSTEM FOR DETECTING RUPTURE OR THINNING OF DIAPHRAGMS |
摘要 |
A diaphragm diagnostic system for use in an industrial field device has a diaphragm and a diagnostic feature. The diaphragm is configured to couple the field device to a process fluid and has a plurality of layers. A first layer of the plurality of layers is exposed to process fluid of an industrial process. A diagnostic feature is coupled to the diaphragm to monitor an electrical parameter of the diaphragm and responsively infer an operative state of the diaphragm based on a change in the monitored electrical parameter. |
