Introduction: Ensuring Reliable Liquid Level Measurement in Harsh Industrial Environments In high-temperature, high-pressure, and highly corrosive industrial environments, ensuring accurate and stable liquid level measurement is a significant challenge. Tuning fork level switches, known for their high precision and reliability, are widely used in various industries. However, their performance largely depends on their core component—the […]

In the field of industrial automation, instrumentation devices are essential for accurate measurement, control, and safe operation of modern production systems. Proper grounding of instrumentation equipment is not only a technical requirement but also a safety-critical measure to ensure reliable operation, signal integrity, and protection from electrical hazards. This article provides a comprehensive overview of

In industrial automation and control systems, the quality of compressed air plays a crucial role in ensuring reliable operation. Among various types of compressed air, instrument air refers to the purified, dry air supplied specifically to pneumatic instruments and control systems. This article explains the differences between plant air and instrument air, and provides a

1. Structural Definitions Symmetrical Cable Structure A symmetrical cable is one in which all conductors (e.g., three-phase power lines) are arranged in a geometrically balanced pattern, typically with: Equal spacing between conductors Identical insulation, shielding, and sheathing across all cores Consistent physical and electrical characteristics Example: A 3-core cable with conductors arranged in an equilateral

When working with pipelines, fittings, and flanges, it is often necessary to switch between different pressure rating systems depending on the region and standards used. PN (Nominal Pressure) and Class Ratings are two of the most widely used pressure standards. However, converting between these two systems isn’t as straightforward as a mathematical formula. The conversion

1. Determination of Pump Selection Parameters 1.1 Physical and Chemical Properties of the Medium The medium’s properties directly affect the pump’s performance, material selection, and structural design. Key considerations include: Corrosiveness, toxicity Presence of solid particles (content and size) Viscosity Tendency to crystallize 1.2 Process Parameters Flow Rate (Q): Minimum, normal, and maximum operational flow

1. Purpose This procedure is established to ensure standardized, professional, and hierarchical management of alarms and interlocks within all departments of the company. It specifies the management content and methodologies applicable to alarms and interlocks associated with production units. 2. Scope This procedure applies to the management of alarms and interlocks across all production units

In industrial control systems, the terms “active signal,” “passive signal,” “dry contact,” and “wet contact” are frequently used. However, these concepts are often confused due to overlapping characteristics and similar application scenarios. This article aims to clarify these concepts, explain their differences, and provide examples to help engineers and technicians make more informed decisions during

1. Introduction In the field of industrial automation, ensuring equipment reliability and early fault detection is essential to maintaining system safety and minimizing downtime. To address this, the NAMUR organization (User Association of Automation Technology in Process Industries, Germany) published NE 43, a guideline that defines how process instruments should signal failure conditions using standardized

In industrial environments, the proper installation of cables—whether for power, control, instrumentation, or data—is vital for both short-term performance and long-term reliability. One of the most often overlooked yet critical aspects of cable installation is the minimum bend radius. Ignoring this factor can lead to cable damage, safety risks, and system malfunctions.
