Avoid malfunctions of combustible gas detectors caused by settings
Combustible gas detectors are mainly used in the petrochemical industry where combustible gases exist, such as gas, petroleum, and chemical industries. They can be used to detect whether there are dangerous leaks in indoor and outdoor places, and are also important instruments to ensure personal safety and production safety. If combustible gas is detected in a specific location, the detector will convert the gas signal into voltage and current signals to transmit to the alarm instrument. The instrument will automatically display the concentration value of the lower explosive limit of combustible gas. When personnel hear the sound and light alarm signal, they will take some safety measures to prevent the occurrence of explosion accidents.
Therefore, combustible gas detectors should be kept away from air conditioning and heating equipment to avoid malfunctions caused by improper placement. Users should also pay attention to preventing electromagnetic interference when using combustible gas detectors. The installation position, installation angle, protective measures, and system wiring of the portable alarm should be designed to prevent electromagnetic interference. Users should pay attention to factors that may cause malfunctions during the use of combustible gas detectors, such as dust, high temperature, humidity, rain, etc. When installing a combustible gas alarm in a location that requires the installation of an exhaust fan, if the exhaust fan is placed adjacent to the combustible gas detector, the leaked combustible gas will not be able to fully spread to the vicinity of the combustible gas alarm, resulting in the inability to detect in a timely manner and causing a missed opportunity. Users should also pay attention to avoiding places with high temperature, high humidity, steam, and oil fumes when using combustible gas detectors. Do not place or hang items on the detector. The installed combustible gas detector cannot be moved arbitrarily. Users should choose products with replaceable sensor probes when using portable alarm devices for ease of use.
Maintaining a combustible gas detector requires communication between the detector and the detection environment. Therefore, it is inevitable for various pollutants and dust in the environment to enter the detector, which can cause damage to the working conditions of the detector. Fixed combustible gas detectors work in harsh environments and are often installed outdoors. Poor maintenance can lead to detection errors or failure of the detector. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent malfunctions.
Combustible gas detector is a detector installed and used in industrial and civil buildings that responds to the concentration of single or multiple combustible gases. The commonly used combustible gas detectors in daily life are catalytic combustible gas detectors and semiconductor combustible gas detectors. Semi conductive combustible gas detectors are mainly used in places such as restaurants, hotels, and home workshops where gas, natural gas, and liquefied gas are used. Catalytic combustible gas detectors are mainly used in industrial places where combustible gases and vapors are emitted.
