Introduction to the Common Faults and Causes of Gas Detectors
Non-standard construction process
For example, if the combustible gas detector is not installed near the equipment where combustible gas is likely to leak, or it is installed adjacent to an exhaust fan during installation, the leaked combustible gas cannot fully diffuse to the vicinity of the combustible gas detector. As a result, the leakage danger cannot be detected in a timely manner by the combustible gas detector. If the combustible gas detector is not reliably grounded, it cannot eliminate electromagnetic interference, which will surely affect the voltage and lead to the failure of inaccurate detection data. Therefore, the combustible gas detector should be reliably grounded during the construction process. If the combustible gas alarm and the wiring terminals are located in places prone to collision or water ingress, it will cause the electrical circuit to be open or short-circuited. When welding, a non-corrosive flux must be used. Otherwise, the joint will be corroded and disconnected, or the line resistance will increase, affecting normal detection. Do not drop or throw the detector on the ground. After the construction is completed, debugging should be carried out to ensure that the gas alarm is in normal working condition.
Improper use by the user
During the use of the gas detector by the user, if air conditioners and heating equipment are installed close to the combustible gas detector, and when the air conditioners and heating equipment are in use, if the cold and warm airflows directly blow through the alarm, it may cause a change in the resistivity of the platinum wire of the alarm, resulting in errors. Therefore, the alarm should be kept away from air conditioners and heating equipment to avoid malfunctions caused by improper installation positions. The user should also pay attention to preventing electromagnetic interference during the use of the combustible gas detector. The installation position, installation angle, protective measures, and system wiring of the gas alarm should be protected from electromagnetic interference. The user should pay attention to the factors that are likely to cause malfunctions during the use of the combustible gas detector, such as dust, high temperature, humidity, rain, etc.
When an exhaust fan needs to be installed in the place where the combustible gas alarm is installed, if the exhaust fan is installed adjacent to the combustible gas detector, the leaked combustible gas will not be able to fully diffuse to the vicinity of the gas alarm, resulting in the inability to detect it in a timely manner and missing the opportunity to deal with the situation. The user should also pay attention to avoiding places where there are high temperatures, high humidity, steam, and cooking fumes when using the combustible gas detector. Do not place or hang any items on the detector. Do not move the position of the installed combustible gas detector arbitrarily. When using the alarm, the user should preferably choose products with replaceable sensor probes for ease of use.
