1. Pressure Sensor (Transducer) Working Principle: Detects a pressure signal and converts it into a usable electrical signal (analog or digital). Applications: Widely used in industrial automation systems such as water resources, electric power, petrochemicals, aerospace, railways, and smart buildings. Features: Provides continuous output (e.g., 4–20 mA, 0–10 V, RS485). Interfaces with PLC, DCS, or […]

Pressure loss—also known as pressure drop or head loss—is a critical concept in fluid engineering. It refers to the reduction in pressure as a fluid flows through a pipe, valve, fitting, or any other component in a system. Understanding and managing pressure loss is essential for the efficient and safe operation of pipelines, pumps, and

Back pressure, as the name implies, refers to the static pressure that exists on the downstream side of a flow system. It represents a form of resistance against the direction of fluid flow and plays a crucial role in various industrial processes involving liquids or gases. This article explains what back pressure is, its key

In physics and engineering, the terms “pressure” and “pressure intensity” (or “stress”) are often confused or used interchangeably. While they are related, they represent different concepts. Understanding their distinction is crucial, especially in technical applications. 1️⃣ What Is Pressure Intensity? Pressure intensity (often simply called pressure) refers to the force applied per unit area. It

1. Introduction In industrial pressure measurement, you often encounter terms like absolute pressure, gauge pressure, and vacuum pressure. Understanding their differences and relationships is essential for accurate pressure monitoring and selection of pressure instruments. This article explains the definitions, formulas, and practical implications of these three types of pressure. 2. Absolute Pressure (P_abs) Absolute pressure

In complex fluid control systems, pressure units can often be confusing, with different terms used to describe seemingly similar concepts. One common source of confusion is the distinction between PN16 and 1.6 MPa. While they may appear equivalent at first glance, their definitions, applications, and implications vary significantly. This article aims to clarify the differences

Pressure control is crucial for the safety, efficiency, and longevity of various industrial and mechanical systems. Secondary pressure reduction, commonly referred to as secondary pressure regulation, involves further reducing and controlling pressure within a system after an initial reduction phase. Maintaining stable pressure at this stage is vital to prevent fluctuations that could lead to

Introduction In process industries such as power generation, chemical manufacturing, and petroleum refining, pressure is a fundamental and critical parameter. It plays a vital role in monitoring equipment status, optimizing thermal systems, and ensuring operational safety. This article provides a detailed explanation of five common pressure types — gauge pressure, absolute pressure, vacuum, negative pressure,

Introduction Pressure measurement is essential in various fields, including engineering, physics, and industrial applications. Understanding the differences between absolute pressure, gauge pressure, and vacuum pressure is crucial for accurate readings and interpretations. This article explores these types of pressure, their significance, and how they are measured. Absolute Pressure Absolute pressure is the total pressure exerted

Introduction In the fields of engineering, manufacturing, and industrial piping systems, pressure class (CLASS) is a crucial standard that determines the pressure-holding capacity of components such as flanges, valves, and fittings. Understanding the relationship between CLASS ratings and nominal pressure (MPa) is essential for ensuring the safety and efficiency of pressure-bearing equipment. This article provides
