Electrical conductivity (EC) is an essential physical parameter used to characterize the ion concentration and soluble inorganic salt content in water solutions. It is widely applied in industrial wastewater treatment, reverse osmosis (RO) and ultrapure water systems, cooling water management, municipal wastewater plant process control, and environmental discharge regulation. Unlike experimental water quality indicators such […]

Overview Control system inspections are essential for preventing failures and ensuring system reliability. A standardized process should be established across three main aspects: hardware, software, and functionality. 1. Preparation for Inspection Tools and Instruments: Multimeter Signal generator Programming software (e.g., PLC programming software) Calibration instruments (e.g., Fluke 754) Documents: Control system schematics I/O list Inspection

Introduction to Equipment Inspections The equipment inspection system is a management method where specific parts of equipment are checked periodically according to certain standards to detect potential faults early. This allows for timely repairs and adjustments, ensuring that the equipment maintains its prescribed functions. It’s important to note that equipment inspection is not just a

The management of spare parts for instrumentation in chemical plants is crucial for ensuring the stability of production processes, controlling maintenance costs, and maximizing economic efficiency. While maintaining a large inventory might tie up substantial funds and warehouse space, insufficient spare parts can lead to costly unplanned downtime, which can far exceed the value of

1. Overview of Electric Heat Tracing Systems Electric heat tracing systems are widely used in chemical, petrochemical, coal-to-chemicals, refining, and water treatment industries to prevent pipeline freezing, maintain process temperature, and ensure stable plant operation during cold weather. Based on heating characteristics and construction, heat tracing cables are mainly classified into: Self-regulating (Self-limiting) Heat Tracing

Client Inquiry: This is a very typical and often overlooked issue in engineering sites. In a temperature measurement system, the Temperature Well, though a small metal component, plays a critical role in the overall instrument system. It is responsible for protection, heat transfer, support, and safety isolation. In other words, the Temperature Well not only
