How to solve these three common faults of combustible gas detectors?
Improper use by the user.
During the installation of the combustible gas detector, the air conditioner and heating equipment should be placed 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 a change in the resistance rate of the platinum wire of the combustible gas alarm, resulting in errors. Therefore, the combustible gas alarm should be kept away from the air conditioner and heating equipment to avoid improper placement and failure. 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 combustible gas alarms should be designed to prevent electromagnetic interference. There are three main ways in which the electromagnetic environment affects combustible gas detectors: airborne electromagnetic wave interference, narrow pulse groups on power and other input/output lines, and human static electricity. For example, when a combustible gas alarm is installed near an air conditioner, it will cause a deviation in the system's detection: the detection line is closely spaced from strong electrical lines such as power lines and lighting lines, and without anti electromagnetic interference measures, the system will also produce detection deviation. 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 diffuse to the vicinity of the combustible gas alarm, resulting in the inability to detect in a timely manner and causing a missed opportunity. In addition, users should also pay attention to the setting of combustible gas detectors in explosion-proof places. For example, Class A factories that emit combustible gases should use explosion-proof combustible gas alarms, and their explosion-proof level should not be lower than the corresponding explosion-proof level requirements of current regulations. 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 combustible gas alarms for ease of use.
