What are the most important things to be aware of in the use of a gas detector?
Firstly, in order to detect gas concentration, it is necessary to ensure 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. Combustible gas detectors work in harsh environments and are often installed outdoors. Poor maintenance and upkeep can lead to errors or failure to detect combustible gas detectors. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent malfunctions.
Grounding should be regularly checked. If the grounding does not meet the standard requirements or is not grounded at all, it can also make the combustible gas detector susceptible to electromagnetic interference and cause malfunctions.
Secondly, during the use of gas detectors by gas alarm users, there is a possibility that the resistivity of the platinum wire of the combustible gas detector may change and cause errors. 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, etc. When exhaust fans need to be installed in places where combustible gas detectors are installed, the combustible gas detectors are placed adjacent to each other, and the leaked combustible gas will not be able to fully spread to the vicinity of the combustible gas detector, 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.
Thirdly, non-standard construction processes can cause combustible gas detectors to malfunction during use. If the combustible gas detector is not located near the equipment that is prone to leakage, or is installed adjacent to the exhaust fan, the leaked substance cannot fully diffuse to the vicinity of the combustible gas detector, thus making it difficult for the leakage hazard to be detected by the combustible gas detector in a timely manner. If the combustible gas detector is not reliably grounded and cannot eliminate electromagnetic interference, it will inevitably affect the voltage and result in inaccurate detection data. Therefore, the combustible gas detector should be reliably grounded during the construction process. The combustible gas alarm and wiring terminals are located in areas that are prone to collision or water ingress, causing electrical circuit breaks or short circuits. Non corrosive soldering flux must be used for welding, otherwise the joint will corrode and detach or increase the line resistance, affecting normal detection. Do not drop or throw the detector to the ground. After construction, debugging should be carried out to ensure that the alarm is in normal working condition.
