  在采用 2 线技术的压力表或温度传感器上的两根导线中,一根连接到电源电压,而另一根将电输出信号传送到压力变送器。输出信号通常为正,因此需要连接到压力变送器的正极。然后需要将负极连接到接地端子或接地端子,以闭合电路。

  原文:

  Of the two wires on a pressure gauge or temperature sensor in 2-wire technology, one is connected to the supply voltage while the other delivers the electrical output signal to the pressure transmitter. The output signal is usually positive and thus needs to be connected to the plus terminal of the pressure transmitter. The minus pole then needs to be connected to the earth terminal, or ground terminal, in order to close the circuit.
