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

Combustible gas detectors are critical safety devices used to detect the presence of flammable gases and mitigate potential hazards. However, whether they need to be equipped with a rain shield depends on the installation environment, device specifications, and operational requirements. Below is a detailed exploration of the factors to consider. 1. Installation Environment Indoor Installations:

Types of Errors Reference Error: Definition: Reference error is the ratio of absolute error to the measurement range, expressed as a percentage. Formula: Reference Error (%) = (Absolute Error / Measurement Range) × 100 Absolute Error: Definition: The difference between the measured result and the true value. Formula: Absolute Error = Measured Value – True

Introduction In the precise world of measurement, not every instrument requires a rigorous calibration process. Certain equipment can reliably operate without calibration under specific conditions. This article outlines the standards and criteria under which instruments, such as ultrasonic level meters, can forego calibration while maintaining reliable and accurate performance. 1. Purpose of Instrument Usage Calibration
