A thermocouple can be used in a furnace to monitor the temperature and ensure safe operation by shutting off the gas supply if the temperature gets too high. This helps prevent overheating and potential hazards. Additionally, the thermocouple can also help maintain efficiency by regulating the temperature accurately, leading to optimal performance of the furnace.
