9200-01-01-10-00 两线传感器

9200-01-01-10-00是一款两线传感器，其工作原理主要基于4~20mA信号为自身提供电能。在这类传感器中，两根导线既用作电源线，又作为信号线，实现电源供应和信号传输的双重功能。

从结构上看，两线制传感器主要由传感器、调理电路以及两线制V/I变换器构成。传感器负责将温度、压力等物理量转化为电参量，调理电路则对传感器输出的微弱或非线性的电信号进行放大、调理，并转化为线性的电压输出。

9200-01-01-10-00在多个方面展现出其优势。首先，由于只使用两根线，其接线简单易懂，安装方便，尤其适合小空间安装。其次，两线制传感器的量程范围灵活，既可以做大量程的，也可以做小量程的。此外，在传输距离较大以及防爆等场合，无源的两线制传感器是更好的选择。

需要注意的是，9200-01-01-10-00两线制传感器的自身耗电（包括传感器在内的全部电路）一般要求不大于3.5mA，以确保能够输出下限4mA值。如果变送器自身耗电大于4mA，那么将无法输出下限4mA值。

在应用中，当PLC的模板输入通道设定为连接两线制传感器时，PLC的模拟输入模板的通道上还需要向外输出一个直流24V的电源，以驱动两线制传感器工作。

总的来说，9200-01-01-10-00因其接线简单、安装方便、量程范围灵活以及适用于特定场合等优势，在工业自动化等领域得到了广泛应用。

The 9200-01-01-10-00 is a two-wire sensor that provides power to itself based on a 4 to 20mA signal. In this type of sensor, two wires are used as both a power line and a signal line to achieve dual functions of power supply and signal transmission.

From the structural point of view, the two-wire sensor is mainly composed of a sensor, a conditioning circuit and a two-wire V/I converter. The sensor is responsible for converting physical quantities such as temperature and pressure into electrical parameters, and the conditioning circuit amplifies and adjusts the weak or nonlinear electrical signals output by the sensor, and converts them into linear voltage output.

The 9200-01-01-10-00 shows its advantages in several ways. First of all, because only two wires are used, its wiring is simple and easy to understand, easy to install, especially suitable for small space installation. Secondly, the range range of the two-wire sensor is flexible, which can be done with large range and small range. In addition, in the case of large transmission distance and explosion protection, passive two-wire sensor is a better choice.

It should be noted that the power consumption of the 9200-01-01-10-00 two-wire sensor (all circuits including the sensor) is generally not greater than 3.5mA to ensure that the lower limit of 4mA can be output. If the transmitter consumes more than 4mA, it will not be able to output the lower limit of 4mA.

In the application, when the PLC template input channel is set to connect the two-wire sensor, the PLC analog input template channel also needs to output a DC 24V power supply to drive the two-wire sensor work.

In general, 9200-01-01-10 has been widely used in industrial automation and other fields due to its advantages of simple wiring, easy installation, flexible range and suitable for specific occasions.
