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

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.

Resistance Temperature Detectors (RTDs) are widely used in industrial applications due to their high accuracy, stability, and repeatability in temperature measurement. One critical component of an RTD is the extension section, which connects the sensing element to the external circuitry. Proper design and implementation of the extension section are essential to maintain the integrity and
In piping systems, the type of flange seal face often determines the upper limit of the entire sealing system. While many focus on flange material and pressure ratings, the importance of matching seal faces is often overlooked. The seal face plays a crucial role in: Gasket compression ability Corrosion resistance to the medium Ease of

In the commissioning of large-scale boiler inlet water flow meters at a major power plant in Jiangsu, China, the flow measurement taken from one of the three pressure tapping points consistently showed higher readings compared to the other two. Despite thorough checks on the instruments and installations, the cause of this abnormality could not be
Explosion protection levels are essential in ensuring safety in environments with flammable gases, vapors, or dust. The classification system defines the appropriate equipment and safety measures based on the characteristics of the hazardous environment. This article provides an in-depth look at explosion protection classifications, focusing on categories, temperature groups, explosion-proof methods, and marking systems. 1.
