What problems will gas detectors encounter?
If the gas detector is used without using the correct method, 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 will mainly follow Let’s talk about the common faults of gas detectors.
Common faults of gas detectors
1. Improper operation methods by users:
When using the gas detector, the user installs the instrument close to air conditioning 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 as far away from air conditioners and heating equipment as possible to avoid installing it in the wrong location, which may cause the instrument to malfunction. When using gas detectors, you also need to pay attention to preventing electromagnetic interference.
2. The installation process is not standardized:
The gas detector malfunctioned due to irregular methods used during the installation of the instrument. If the gas detector is not correctly installed near the leaking gas, or is installed close to the exhaust fan, the leaked gas cannot fully diffuse 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 promptly detected. Detected by flammable gas detector. If the gas detector and wiring port are installed in a place prone to collision or water intrusion, it will easily cause the electrical circuit to break or short circuit. Non-corrosive flux should be used when welding instruments, otherwise the joints will be corroded or the circuit resistance will increase, causing the normal structure to be affected. 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 gas concentration, the gas detector must be used correctly in the environment. Since various polluting gases and some dust will enter the instrument in the environment, some of the current gas detectors are used for methane detection. It is outdoors. If the instrument is not maintained during use, it may cause measurement errors or failure of the gas detector.
