Instrumentation and electrical systems can be differentiated from the following aspects: 1. Definitions and Functions Instrumentation: Definition: Refers to devices or systems used to measure, display, control, and record physical quantities such as temperature, pressure, flow, and liquid levels. Function: Primarily focused on the precise detection and monitoring of various physical quantities to provide accurate […]

Introduction Process detection and control instruments play a crucial role in ensuring production safety and smooth operation. Whether an instrument is functioning properly is directly related to the continuity and safety of chemical production. Therefore, maintaining and servicing instruments is essential. Instrument Maintenance Daily maintenance of instruments reflects the preventive ideology of Total Quality Management

1. Basic knowledge of instruments Instruments are key components in industrial automation systems, and are mainly used to measure, record, control and adjust various physical quantities, such as temperature, pressure, flow, liquid level, etc. The basic function of instruments is to achieve signal conversion, that is, to convert the measured physical quantity into a standard

After being in use for a period of time, electromagnetic flowmeters may suddenly become inaccurate, which undoubtedly causes significant inconvenience to industrial production. This article will explore the reasons why electromagnetic flowmeters become inaccurate after some time and offer solutions to these problems. First, let’s analyze the possible causes: Sensor Contamination: During operation, the sensor

Flammable gases can be classified as either single flammable gases or mixed flammable gases, both of which have flammable and explosive properties. The explosion limit refers to the concentration range within which a flammable gas, when mixed with an oxidizing gas, will explode under standard testing conditions. Oxidizing gases can include air, oxygen, or other

Volumetric flow meters play a vital role in the chemical industry, where accurate measurement and control of fluid flow are essential for maintaining product quality, optimizing production processes, managing energy consumption, and ensuring safety and environmental compliance. The primary applications include: 1. Accurate Measurement of Fluid Flow 1.1 Measurement of Raw Materials: In chemical production,

Measuring liquid flow in large-diameter pipelines is critical for applications such as municipal water supply, industrial cooling water systems, and wastewater treatment plants. The challenge in these systems is ensuring accurate, stable, and reliable measurement while also maintaining ease of installation and maintenance. Several flow measurement techniques are commonly employed for large-diameter pipelines, each with

Instrument numbering holds significant value in industrial production, primarily reflected in the following aspects: 1. Identification and Localization Unique Identification: Every instrument has a specific instrument number, similar to an identification card, enabling precise recognition and distinction of different instruments. This allows operators and maintenance personnel to quickly and accurately locate specific instruments, improving work
