In many engineers’ minds, digital signals are often considered more advanced, more accurate, and more stable than analog signals. At first glance, this seems absolutely correct. However, in real industrial environments with strong electromagnetic interference (EMI), low signal-to-noise ratio (SNR), or insufficient error correction mechanisms, analog signals may sometimes appear more stable than digital communication. […]

In industrial automation, systems may look complex, but most process issues can often be traced back to a few fundamental measurement variables. To put it simply, if these key parameters are not measured accurately and controlled properly, goals such as process optimization, production safety, equipment protection, and product quality become difficult to achieve. In most

Particle Size Distribution (PSD) is a critical parameter for characterizing the properties of particulate materials. It describes the proportion of particles of different sizes within a sample. In industries such as pharmaceuticals, powder processing, and multiphase systems, PSD directly influences material performance, process efficiency, and product quality. Therefore, accurately understanding and controlling PSD—particularly parameters like

In industries such as petrochemical, natural gas, pharmaceuticals, and dust processing, the classification and management of explosive hazard zones are not only technical concerns but also safety regulations and mandatory standards. The depth of understanding directly influences the effectiveness of the explosion-proof system in any enterprise. This article provides a comprehensive professional interpretation of explosive

Both chemical and paper industry instruments belong to the category of process automation, but they differ greatly in terms of process media, operating conditions, control objectives, and safety levels. This results in significant differences in selection, structure, accuracy, protection, and functional priorities. Below is a detailed comparison across various dimensions: 1. Core Operating Conditions and
