Explanation of Common Problems of Gas Detector
If the gas detector is not used in the correct way, it may cause it to malfunction. Once a malfunction occurs, it may lead to inaccurate measurements and other results. In order to avoid this situation affecting us, today we mainly follow Let's talk about the common faults of gas detectors.
Common faults of gas detectors
1. Improper user operation method:
In the process of using the gas detector, the user installs the instrument near the air conditioner and heating equipment, which will cause cold and warm air to flow through the gas detector. At this time, the resistance of the platinum wire in the gas detector may change, so when using Keep the gas detector away from air conditioners and heating equipment as much as possible to avoid installing it in the wrong place and causing the instrument to malfunction. When using a gas detector, it is also necessary to pay attention to anti-electromagnetic interference.
2. The installation process is not standardized:
During the installation of the instrument, non-standard methods were used to cause the gas detector to fail. If the gas detector is not installed correctly near the leaking gas, or it is installed close to the exhaust fan, the leaked gas cannot be fully diffused to the vicinity of the gas detector, so that the leaked gas cannot be detected by the gas detector in time, and the danger cannot be detected in time. Detected by a flammable gas detector. If the gas detector and wiring ports are placed in places that are prone to collision or water ingress, it will easily lead to disconnection or short circuit of electrical circuits. Non-corrosive flux should be used when welding the instrument, otherwise the joints will be corroded and disconnected or the line resistance will be increased, which will affect the normal structure. After the installation is completed, use the instrument for debugging to ensure that the gas detector is in normal working condition.
3. Maintenance:
If a gas detector is used to measure the gas concentration, the gas detector must be used correctly in the environment. Due to the presence of various polluting gases and some accumulated dust in the environment, some of the current gas detectors are used for methane detection. If it is outdoors, if the instrument is not maintained during use, it may cause errors or non-detection in the measurement of the gas detector.
The above are the common faults of gas detectors, which can be avoided. During the use of gas detectors, attention should be paid to regular maintenance of the instruments.
