热电偶在许多测量任务中往往不能单独使用,因为它需要冷端温度装置(例如冰筒)。借助于AD594型热电偶信号转换器即可组成使用热电偶作为测量器件的测量线路,不再需要冷端装置。该集成块的主要优点是:价廉、使用方便,在5～15V范围内用单电源即可驱动,且可直接与J、K、R、T型热电偶连接。这种集成型转换器可用作极限值报警的测 Thermocouples are often not used alone in many measurement tasks because they require cold-end temperature devices (such as ice tubes). With the help of the AD594 thermocouple signal converter, a thermocouple can be used as a measuring device for measurement lines, eliminating the need for cold junction devices. The main advantages of the manifold are: low cost, easy to use, can be driven with a single power supply in the range of 5 ~ 15V, and can be directly connected with J, K, R, T type thermocouple. This integrated converter can be used as a limit alarm
