Method of and apparatus for automated sensor diagnosis through quantitative measurement of one of sensor-to-earth conductance or loop resistance |
摘要 |
A method of and apparatus for automated sensor validation diagnosis during and before operation of pluralities of sensors connected by multiplex sequence in a loop with analog-to-digital converter voltage measurement apparatus responsive to the sensor signals for the primary task of validating a process under monitor by the sensors, wherein provision is made for periodically or selectively quantitatively measuring either (or both) sensor-to-earth conductance or loop resistance of the sensors to insure sensor viability.
