Gas detectors play a crucial role in ensuring safety by identifying potentially hazardous gases in various environments. This article explores the working principles and types of detectors for both combustible and toxic gases. 1. Combustible Gas Detectors Combustible gas detectors are essential for monitoring environments prone to flammable gases. Common types include catalytic combustion, semiconductor,

A portable gas detector is a vital safety tool for detecting harmful gases in industrial and hazardous environments. Proper usage is crucial to ensure accuracy and reliability. Below is a comprehensive guide for correct usage: 1. Pre-Use Inspection Before using the gas detector, conduct the following checks: Battery Status: Ensure the battery is sufficiently charged.

In the instrumentation industry, selecting the right material is a critical decision that directly impacts the durability, performance, and cost-efficiency of equipment. Among the commonly used stainless steel materials, SCS14A, SUS316, CF8M, and 316L are well-known for their corrosion resistance and mechanical properties. However, each material has unique characteristics that make it suitable for specific

Instrument rooms house precision equipment and sensitive electronics, which require specific considerations when choosing fire extinguishers. According to the Code for Design of Extinguisher Distribution in Buildings (GB50140), fires in such environments are classified as Class E fires, which involve energized electrical equipment. Therefore, fire extinguishers must meet high electrical insulation standards to effectively suppress

Instrument calibration is a crucial process in ensuring measurement accuracy and reliability. Despite strict metrology standards and guidelines, errors can still occur due to improper implementation or uncontrollable factors. These errors may compromise the validity of calibration results. Below, we explore common errors in instrument calibration and provide recommendations for minimizing them. 1. Errors in

Tank area instrumentation is critical for monitoring and controlling parameters in storage facilities, ensuring operational efficiency, safety, and regulatory compliance. This article explores the key types of instruments used in tank areas, their working principles, selection criteria, and best practices for maintenance. 1. Level Measurement Instruments a.

1. What is Ammonia Slip? Ammonia slip refers to the phenomenon where ammonia, used as a reducing agent in industrial denitrification processes, escapes into the atmosphere without fully reacting. Denitrification technologies such as Selective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR) are employed to reduce nitrogen oxides (NOx) emissions by converting them into nitrogen

Residual Current Devices (RCDs), commonly referred to as leakage protection devices, are essential components of electrical safety. They belong to the family of circuit breakers, alongside air circuit breakers and isolating switches. In circuit diagrams, RCDs are often denoted by their acronym. Unlike air circuit breakers that provide short-circuit and overload protection, RCDs add a
