Instrumentation

When we talk about instrumentation construction drawings, many people may think it’s simply a matter of reviewing blueprints. But what if I told you that a single oversight could paralyze an entire project, or even result in safety accidents? Would you still underestimate its importance? Let me share a real-life example: In a large-scale chemical […]

Integrated and remote (split-type) instruments are two common structural forms of instrument devices, each with distinct features and suitable applications. Making the right choice between these two depends on the specific application scenarios and operational needs. Below is a comprehensive guide to help determine the most appropriate option. Installation Environment and Conditions Harsh Environments: For

In industrial automation and control systems, the selection and arrangement of cables are crucial for system stability and ease of maintenance. The following is an analysis of the advantages and disadvantages of two methods: using multi-core cables to connect to the device terminal junction box, then branching out to instruments, and directly connecting cables to

Abstract The explosion-proof markings Ex d and Ex db are distinct classifications under different standards for explosion protection in electrical equipment. Ex d refers to the older standard GB3836.2-2010, which specifies requirements for equipment protected by a flameproof enclosure. Ex db, on the other hand, complies with the updated standard GB/T3836.2-2021, also designed for explosive

In the field of industrial automation, Distributed Control Systems (DCS) have long played a vital role, often referred to as the “nervous system” of industrial production. They ensure the efficiency and stability of production by centrally monitoring and distributing control across the entire process. However, with the rapid development of technology and the expansion of

In automated production processes, level detection and monitoring play a critical role across various industries, such as food and beverage, chemicals, pharmaceuticals, and semiconductors. From machine cooling to lubrication systems, the ability to monitor liquid levels directly impacts product quality and can even determine whether the production process runs smoothly. For engineers, selecting the appropriate

Calibrating your pH meter is an essential step to ensure accurate and reliable measurement results. By properly calibrating your pH meter, you can improve the precision of readings, which is crucial for various applications in laboratories, industrial processes, and environmental monitoring. Below is a step-by-step guide to calibrating a pH meter: 1. Preparation Clean the

Instrumentation plays a crucial role in the petrochemical industry, providing monitoring, early warning, and indication functions. Improper installation can not only affect the normal operation of the entire project but also pose severe safety risks, potentially leading to hazardous chemical accidents. This document aims to provide an in-depth understanding of the standard guidelines for instrument

The accuracy of measuring instruments directly impacts the quality of a company’s production processes and final products. In manufacturing enterprises, managing these instruments effectively is crucial to ensuring quality control. However, given the sheer volume of measuring instruments—sometimes numbering in the hundreds or thousands—their calibration, maintenance, and management pose significant challenges, especially in medium-to-large-scale manufacturing

In Distributed Control Systems (DCS) and industrial automation, setting up Low-Low (LL) and High-High (HH) alarms is crucial for providing comprehensive safety protection and operational guidance. While Low (L) and High (H) alarms are already in place to signal when process parameters deviate from their normal ranges, LL and HH alarms are introduced to handle
