    • An assembly includes a thermocouple, a cold junction sensor, and a circuit. The thermocouple has a process end and a cold junction end. The cold junction end has first and second cold junction terminals. The cold junction sensor is supported near the cold junction end and configured to measure temperature at the cold junction end. The circuit is electrically connected to the cold junction sensor and to the first and second cold junction terminals. The circuit is configured to produce a thermocouple signal as a function of voltage across the first and second cold junction terminals and to produce a cold junction sensor signal as a function of temperature of the cold junction end as measured by the cold junction sensor. The circuit is further configured to calculate a correlation between the thermocouple signal and the cold junction sensor signal.
    • 组件包括热电偶,冷接点传感器和电路。 热电偶具有工艺端和冷端。 冷端具有第一和第二冷端子。 冷端传感器支撑在冷连接端附近,并配置为测量冷端端的温度。 电路电连接到冷端传感器和第一和第二冷端子。 电路被配置为产生作为第一和第二冷端子两端的电压的函数的热电偶信号,并且产生冷结传感器信号作为由冷端传感器测量的冷端的温度的函数。 电路还被配置为计算热电偶信号和冷端传感器信号之间的相关性。
