PT100 temperature signal analog output device

The utility model discloses a PT100 temperature signal analog output device, which can realize dual-channel PT100 temperature signal output. Passive output does not need power supply, so that people do not need to worry about no power supply or battery power shortage on site; the gear shifting knob convenient to operate is arranged, and a specific temperature value corresponding to each gear instead of a corresponding resistance value is directly displayed on the knob dial, so that the process of changing the temperature into the corresponding resistance value can be omitted, and the operation is simpler, more convenient and quicker. 本实用新型公开了一种PT100温度信号模拟输出装置，可实现双通道PT100温度信号输出；无源输出无需供电，不用担心现场无供电电源或电池欠电；具有便捷操作的拨档旋钮，并且旋钮刻度盘上直接显示每档对应具体的温度数值，而不是显示对应的电阻值，可省去将温度换成对应电阻的过程，使得操作更加简便快捷。
