Understanding Analog Signals and Their Typical Applications

PLC /

Introduction to Analog Signals Analog signals are physical quantities that change continuously over time, such as voltage, current, pressure, speed, and flow rate. These signals are widely used in industrial automation for sensing, monitoring, and controlling physical parameters. Common examples include 0–10V voltage signals and 4–20mA current signals, which can be processed using Programmable Logic […]

Why Control Valves Become Unstable: The Real Problem May Be the Positioner

Valve /

In process automation, control valves are the final elements responsible for executing the control signal. However, due to friction, fluid forces, actuator limitations, and other mechanical factors, the actual valve position often fails to match the input signal. A valve positioner—commonly referred to simply as a “positioner”—is the key device designed to eliminate this deviation.
