How important is the gas detector?
The importance of gas detectors. Gas detectors are instruments used to detect changes in the concentration of harmful gases in the work site. In the production process, factories not only need pure industrial gases as raw materials, but also produce a variety of highly pure derivative gases during the production process. These gases often have certain hazards, so they need various high-sensitivity, high-density gases. Accurate and highly selective gas detection instruments are used for monitoring to prevent leakage of industrial gas raw materials or excessive derived gases, and to monitor at all times to reduce hidden dangers.
Gas detection plays a very important role in the production of industrial enterprises. It is the key to preventing accidents and ensuring the smooth progress of safe production. It is also a guarantee for the safety of production personnel and surrounding people. Many accidents are often caused by inadequate supervision of gases. It is really heartbreaking to know that they can be avoided, but they end up being accidents. We also hope that the majority of manufacturing companies can take this as a warning and improve gas detection supervision.
The detector measures the air. Once the test passes, the detector enters a continuous monitoring state. The airflow passes through the panel grid and reaches the sensor. The sensor responds to the measured gas concentration. The diffusion type only monitors the gas that surrounds the detector momentarily. The pump sucks The method allows for remote measurement through the sampling tube. If harmful gases are found, the detector will alarm itself.
When detecting toxic gases, a toxic gas alarm is used. As we all know, the gas detector plays a vital role in the concentration detection of the entire gas alarm. The detector contains a gas sensor inside, which is also a very important component. When detecting toxic gases, electrochemical sensors are used, and their service life is generally about one and a half to two years.
Electrochemical sensors work by reacting with the gas being measured and producing an electrical signal proportional to the gas concentration. A typical electrochemical sensor consists of a sensing electrode (or working electrode) and a counter electrode, separated by a thin electrolytic layer.
Normally, each sensor corresponds to a specific detection gas, but no gas detector is absolutely effective. Therefore, when selecting a gas sensor, you should be aware of the detection interference of other gases on the sensor to ensure its accuracy in detecting specific gases.
Each gas detector has its fixed gas concentration measurement range. Only by completing the measurement within its measurement range can it ensure accurate measurement. Measuring beyond the measurement range for a long time can easily cause permanent damage to the sensor.
