摘要: An improved open circuit detector for testing a thermocouple an condition. The includes generator providing and sourcing tone signal to the thermocouple, wherein has known frequency amplitude. A monitor analyzes amplitude of particular component across thermocouple. If exceeds predetermined threshold, output is provided indicating condition
