2025-11-09

A turbidity sensor is a high - precision instrument based on optical technology. It is used to measure the degree to which suspended particles in water impede light, thereby quantifying the turbidity of water quality. Its core function is to monitor the transparency of water bodies in real - time, and ensure long - term stability and accuracy through an intelligent design. This article will systematically analyze the key features of this device from three aspects: working principle, technical advantages and applicable fields. I. Working Principle: The Combination of Optical Technology and Intelligent Algorithms The measurement of a turbidity sensor relies on the principle of infrared scattered light. Its interior consists of an infrared emitting tube and a receiving tube. When the light source emits infrared light of a specific wavelength (such as 860nm) through the water to be measured, suspended particles will scatter and absorb the light. The sensor detects the intensity of scattered light in the 90° direction and conducts a dual - channel analysis in combination with the transmitted light signal. It calculates the turbidity value using the ratio of scattered light to transmitted light. This dual - beam design eliminates light source fluctuations and environmental interference...

Nitrogen Oxide Sensor: Detailed Explanation of Technical Principle, Core Functions, and Application Fields

2025-10-22

The nitrogen oxide sensor (NOx sensor) is one of the core components of automobile exhaust emission control. It is mainly used to detect the concentration of nitrogen oxides (NOx) in the exhaust gas, including harmful gases such as NO and NO2. As a key part of the diesel engine SCR (Selective Catalytic Reduction) system, gasoline engine exhaust treatment system, and off - road machinery emission control, its technical principle and performance directly affect the vehicle's ability to meet environmental protection standards. Technical Principle The nitrogen oxide sensor operates based on the electrochemical principle. Its core element is a porous zirconia (ZrO2) ceramic tube with a platinum electrode coated on its surface. When the sensor probe is exposed to the exhaust gas environment, the combination of the conductivity of oxygen ions in the solid electrolyte (such as yttria - doped zirconia YSZ) and the catalytic performance of the NOx - sensitive electrode promotes the occurrence of an electrochemical reaction. The difference in the NOx concentration in the exhaust gas causes a potential difference between the electrodes, which is then converted into a measurable current signal. The built - in control chip of the sensor processes the current signal into a standard CAN bus digi...

A Comprehensive Analysis of Gas Leak Detection Methods: Key Measures for Ensuring Safety

2025-10-19

Gas leak detection is a crucial aspect of safe production, energy transportation, and environmental protection. Whether it is the use of household gas or the management of industrial gas equipment, timely detection of leaks can effectively prevent the risks of fire, explosion, and environmental pollution. This article will systematically review the commonly used detection technologies to help users select the optimal solution based on their specific scenarios. I. Traditional Detection Methods: Simple and Efficient Preliminary Screening 1. Olfactory Identification Method Natural gas or liquefied petroleum gas is usually added with odorants such as hydrogen sulfide, which produces an odor similar to that of "rotten eggs" when there is a leak. This method relies on human senses and is suitable for rapid early warning in household environments. However, it may become ineffective due to olfactory fatigue in the case of minor leaks or long - term exposure. 2. Soap Solution Smearing Method Apply dishwashing liquid or soap solution to the pipe joints, valves, and other potential leak points. If continuous bubbles appear, it confirms the presence of a leak. This method is simple to operate and low - cost, making it particularly suitable for regular self - inspections by ...

2025-10-15

A radiation detector is a key instrument for detecting and measuring ionizing radiation in the fields of nuclear science and industry. Its core function is to convert radiation energy into electrical signals that can be quantitatively analyzed. Modern detectors play an irreplaceable role in fields such as nuclear safety monitoring, environmental assessment, and medical diagnosis. The technological evolution of detectors has always revolved around detection accuracy, environmental adaptability, and multi - scenario applications. Analysis of Core Performance Indicators 1. Detection Efficiency: It refers to the ratio of the number of particles actually recorded by the detector to the total number of incident particles in the same period. This indicator is affected by multiple factors such as geometric conditions (e.g., the solid angle of the sensitive area), material attenuation (material shielding effect), interaction probability (probability of reaction between rays and the medium), and recording efficiency (signal threshold setting). For example, for high - energy particles, the penetration loss of the detector shell needs to be considered, while low - energy particles are more susceptible to environmental noise interference. 2.
