RESISTANCE BASED PROCESS CONTROL DEVICE DIAGNOSTICS |
| 摘要 |
A device in a process control system (2) includes an electrical element (210) which has a resistance (212). Self heating circuitry (208) coupled to the element (210) provides a self heating signal related to the resistance (212) of the element (210). Diagnostic circuitry (202) provides a diagnostic output as a function of the self heating signal output. |
