Process instruments are devices used in the field of industrial automation to measure and control process variables (such as temperature, pressure, liquid level, flow, etc.). In process control systems, sensors or transmitters communicate with the control system through electrical signals, and this communication method is usually divided into two-wire, three-wire and four-wire systems. These three […]
