Gas detector malfunction brief
1、 The construction process is not standardized; Non standardized construction processes can cause combustible gas detectors to detect faults during use. If the combustible gas detector is not located near the combustible gas detector that is easy to leak, or is installed adjacent to the Whole-house fan, the leaked combustible gas detector cannot be fully spread to the combustible gas detector, so that the leakage danger cannot be detected by the combustible gas detector in time. If the combustible gas detector is not reliably grounded and cannot eliminate electromagnetic interference, it will inevitably affect the voltage and cause 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 prone to collision or water ingress, causing open or short circuits in electrical circuits. Welding must use non corrosive flux, otherwise the corrosion at the joint will detach or increase the line resistance, which will affect normal detection. Do not drop or throw the detector onto the ground. After construction, debugging should be carried out to ensure that the movable alarm is in normal working condition.
2、 Improper use by users; During the use of gas detectors by gas alarm users, the air conditioning and heating equipment should be installed close to the combustible gas detector. If the cold and warm air flow directly blows through the portable alarm during the use of air conditioning and heating equipment, it may cause changes in the electrical resistivity of the portable alarm platinum wire and cause errors,
Avoiding gas detector malfunctions
Therefore, the movable alarm should be kept away from air conditioning and heating equipment to avoid malfunctions caused by improper positioning. Users should also pay attention to preventing electromagnetic interference during the use of combustible gas detectors. The installation position, installation angle, protective measures, and system wiring of the movable alarm should be protected from electromagnetic interference. Users should pay attention to factors that can cause malfunctions during the use of combustible gas detectors, such as dust, high temperature, humidity, rain, etc. When Whole-house fan is required to be installed in the place where combustible gas alarm is installed, if the Whole-house fan is set adjacent to the combustible gas detector, the leaked mobile will not be able to fully spread to the vicinity of the mobile alarm, resulting in failure to detect in a timely manner, which will make the fighter happy. Users should also pay attention to avoiding areas where high temperatures, humidity, steam, and oil fumes can reach when using combustible gas detectors. Do not place or hang items on the detector. The installed combustible gas detector cannot move the device's position arbitrarily. Users should try to choose products with replaceable sensor probes when using portable alarms for ease of use. In order to detect the concentration of combustible gas in the maintenance of the detector, it is necessary to communicate with the detection environment. Therefore, it is inevitable that various polluting gases and dust in the environment enter the detector, and the damage caused to the working conditions of the detector is objective. The working environment of combustible gas detectors is relatively harsh, and many are installed outdoors, Poor maintenance and upkeep will result in errors or failure to detect the body alarm. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent malfunctions. Grounding should be regularly tested. Failure to meet standard requirements or not being grounded at all can also make combustible gas detectors susceptible to electromagnetic interference and cause malfunctions. It is recommended to conduct response testing on the standard gas used in various instruments before use to ensure that the instruments truly play a protective role. The combustible gas alarm and toxic gas alarm, like other analytical and detection instruments, are measured using a relative comparison method: first, the instrument is calibrated with a zero gas and a standard concentration of gas, and the standard curve is stored in the instrument. During the measurement, the instrument compares the electrical signal generated by the gas concentration to the electrical signal of the standard concentration, and calculates the accurate gas concentration value. Therefore, zero calibration of the instrument at any time and frequent calibration of the instrument are essential tasks to ensure accurate measurement.
In general, gas detectors are prone to malfunctions when users do not have proper usage rules or when the usage process is not standardized. No wind, no waves, so there must be a reason for the malfunction. So the editor suggests that if there is a malfunction when using a gas detector, you can first recall whether you have used it correctly, and then find the cause of the malfunction and solutions
