Thermocouple Open-Circuit Detection Circuit And Method |
摘要 |
<p>A method for detecting an open-circuit in an external thermocouple network includes these steps: (a) injecting a current pulse of a predetermined duration into the external thermocouple network; and (b) measuring the voltage across the pair of terminals after a time period following the predetermined duration. In one example, the time period is sufficiently long to allow the current pulse to dissipate from the external thermocouple circuit when a thermocouple in the external thermocouple network does not have an open circuit. The thermocouple network may include a resistor-capacitor network provided between the thermocouple and one of the terminals.</p> |
