| Abstract: | As the requirements for low consumption and remote transmission are increasing, the two-wire instruments are used widely. In this paper, the advantages and the structure of the two-wire transmitter are introduced. And the operation principle is explained in detail. On the base, it has designed the two-wire pressure changer which is composed of pressure bridge, recuperating circuit and the two-wire V/I inverter. Also, how to increase the stability and security is discussed. |
