Main application fields of gas detectors
As an important branch of instrumentation, gas detection instruments (also known as "gas detectors") are widely used in various fields, including industry, agriculture, transportation, technology, environmental protection, national defense, aerospace, and daily life. Usually, industrial process gas monitoring and analysis instruments are classified into the field of analytical instruments. Common gas detection instruments are usually miniaturized, portable or fixed, independent or connected to a network, and are widely used in industrial sites such as petroleum, chemical, metallurgical, mining, pharmaceutical, semiconductor processing, spray coating packaging, as well as in households, shopping malls, liquefied gas stations, gas stations, gas stations, and other civil/commercial areas that require fire prevention, explosion prevention, and poisoning prevention Places with air pollution, as well as agricultural greenhouse gas detection, biogas analysis, biogas safety monitoring, environmental emergency accidents, terrorist attacks, hazardous material storage and transportation, etc
Working principle of gas detector
Nowadays, with the improvement of people's safety awareness, in addition to chemical plants, gas detectors have also been installed in other harmful gases, real-time monitoring of harmful gases in the air, in order to timely detect leaked gases. Although gas detectors play an important role, little is known about the working principles of gas detectors. Do you know how gas detectors work? The following series will introduce you:
Working principle of gas detector:
The working principle of a gas detector is to detect a certain amount of gas using electrochemical principles. After the inductor is sintered, it enters the inductor through the breathable film on the inductor. The electrode and electrolyte of the inductor consume oxygen, generating a current between the anode and cathode. When current passes through the inductor, the positive electrode of lead is oxidized into lead oxide, and the output current intensity is linearly related to oxygen concentration. The rapid response ability of the sensor enables it to continuously monitor air or process gases.
A gas detector is an instrument that detects gas concentration and leakage points in the environment, with a printable mobile gas detector. If you don't know where the leak is, use this instrument to find the leak point. The higher the concentration, the leakage point. In terms of structure, it is a product used for the separation of meter head detection probes, which can be used as a handheld mobile detection or online desktop detection, suitable for certain specific locations.
