Introduction In modern industrial automation, managing multiple electric motors efficiently and safely is a significant challenge. A Motor Control Center (MCC) is a crucial solution designed to centralize and streamline motor management. Widely used in industries such as oil & gas, metallurgy, mining, water treatment, and power generation, MCCs play an essential role in motor […]

A Manufacturing Execution System (MES) is a crucial production management system designed for manufacturing enterprises. It connects the enterprise’s planning layer (ERP) with the on-site control layer (PLC, SCADA, etc.), enabling real-time monitoring of production processes, data collection, quality management, and process execution. The main goal is to improve production efficiency, product quality, and responsiveness.

In chemical production, startups and shutdowns are routine but critical operations. Short-term shutdowns generally have minimal impact on instruments, with limited adjustments needed by instrumentation personnel. However, this document focuses on large-scale shutdowns and startups, such as those due to major overhauls, extensive stoppages, or events requiring prolonged halts and subsequent restarts of operations. Note

Introduction Japanese Industrial Standards (JIS) define various thread types for different industrial applications. These threads are widely used in mechanical components, piping systems, and precision instruments. This article provides an overview of the most common JIS thread types, their characteristics, applications, and examples. 1. JIS Parallel Pipe Thread (JIS B 0202) Designation: PF (Equivalent to

1. Incident Overview In chemical production or other industrial scenarios involving instrument heat tracing and steam systems, errors during the welding of heat tracing pipes can lead to severe issues. For example, heat tracing pipes may be mistakenly connected to oil system pipelines in the steam system or accidentally linked to isolated oil systems during

The installation height of combustible and toxic gas detectors is a critical factor in ensuring the safety and effectiveness of gas detection systems. Proper installation height depends on the physical properties of the gas, the characteristics of the detection environment, and the location of potential gas release points. Below is a detailed guide on determining

Instrument verification and calibration reports are critical documents in the metrology industry. Companies often conduct testing and measurement to obtain these certificates, which serve two primary purposes: ensuring compliance with regulatory audits and maintaining cost control to support smooth production operations. However, are verification and calibration reports the same? What are the key differences between

Introduction In the modern manufacturing landscape, enterprises are under constant pressure to enhance efficiency, ensure compliance, and optimize resource utilization. This challenge is particularly pronounced in the chemical industry, where precision, safety, and regulatory compliance are paramount. One technological solution that has gained widespread attention is the Manufacturing Execution System (MES). An MES system acts

In many industrial projects, temperature measurement is essential, and the primary sensors used are thermocouples and resistance temperature detectors (RTDs). When selecting a temperature sensor for a specific location, the choice between a thermocouple and an RTD depends on several factors, including temperature range, accuracy, and installation conditions. This article explores the differences between these

1. Confirmation and Validation of Calibration Methods in Metrological Testing 1.1 Control and Management of Calibration Methods Laboratories must implement effective control and management over the metrological testing and calibration methods they employ. This includes establishing clear criteria for when a new method should be introduced and continuously monitoring the development of metrological testing and
