What are the typical reasons that flammable gas detectors get damaged?
The combustible gas detector is a kind of gas detection equipment for detecting the concentration of combustible gas leakage. It mainly uses sensors to detect the type, composition and content of combustible gas in the environment. However, many factors may affect the use of combustible gas detectors during use and cause damage. So what are the common reasons for the damage of combustible gas detectors?
Common reasons for damage to combustible gas detectors:
1. Improper use by the user (such as the temperature is too high)
When the user is using the detector, install the air conditioner and heating equipment close to the combustible gas detector. When using the air conditioner and heating equipment, if the cold and warm air flow directly blows through the combustible gas alarm, it may cause the gas alarm to go off. The resistivity of platinum wire changes and errors occur. Therefore, the gas alarm should be kept away from air conditioners and heating equipment to avoid failures caused by improper setting. Users should also pay attention to anti-electromagnetic interference when using a reputable combustible gas detector.
2. Irregularities in the construction process (such as poor grounding during construction)
Irregularities in the construction process will cause the combustible gas detector to detect failures during use. If the detector is not located near the flammable gas that is easy to leak from the equipment, the leaked flammable gas cannot be sufficiently diffused to the vicinity of the detector, so that the dangerous leakage cannot be detected by the detector in time. The combustible gas detector cannot be grounded, and electromagnetic interference cannot be eliminated. It will definitely affect the voltage and cause inaccurate detection data. Therefore, the detector should be grounded during construction.
3. Improper maintenance and maintenance in the later period (such as long-term contact with chemical substances)
The combustible gas detector needs to detect combustible gas information, so that the detector communicates with the detection environment, so it is unavoidable for various polluting gases and dust in the environment to enter the detector, and the damage to the working conditions of the detector is Objectively speaking, the working environment of combustible gas detectors is relatively harsh, and many of them are installed outdoors. Poor maintenance will lead to errors or non-detection of gas alarms.
4. Other major sudden accidents (such as short circuit and open circuit, etc.)
The reason why it is recommended that each enterprise set up a special flammable gas detector maintenance department is because this kind of instrument takes an important responsibility, and it is necessary to avoid accidents. Water, causing electrical circuit breaks or short circuits, etc., such unexpected accidents may cause detection failure, which is also an important factor to damage.
