The device commonly utilized to measure the temperature of the refrigerant in a system is a thermocouple. A thermocouple consists of two different types of metals joined at one end, and it generates a voltage that varies with temperature, allowing for precise temperature measurements. This feature makes it particularly suitable for applications where monitoring the refrigerant temperature is crucial for efficient system operation and performance diagnostics.

In contrast, a pressure gauge is used for measuring the pressure within the system, which, while important, does not provide direct information about the refrigerant's temperature. Similarly, a thermostat controls the temperature in a space but does not measure refrigerant temperature directly; its primary function is as a switch responding to temperature changes in the environment. A temperature sensor can measure temperature, but it can refer to various types of sensors inclusive of thermocouples. Therefore, while temperature sensors are used broadly, the specific application of measuring refrigerant temperature aligns most accurately with the thermocouple's capabilities.
