Gas detectors are widely used in various fields and have made great contributions to avoiding accidents such as fire, explosion, poisoning, and suffocation. But the same equipment, after buying it, some people can use it for several years without problems, while some people will encounter failures every few days.
You must know that every product of a regular manufacturer is strictly inspected before shipment, and the probability of product quality problems is not high. For example, Kailu Electronics has to go through 8 rounds of quality inspection before and after.
So, what are the other most common causes of failures?
First, environmental impact
The gas detector is a very precise instrument, especially the sensor has very sensitive electronic components. If it is too close to the heating equipment or the equipment that can emit high temperature, the cold and warm air will cause The resistance of the gas detector changes, which makes the data inaccurate during detection. Therefore, in order to avoid the failure of the gas detector, do not place it near the heat source equipment when using and placing it, and use it in full accordance with the temperature range calibrated in the manual.
Second, the installation problem
Some types of gas detection alarms are installed and used after installation, and if they are not installed properly, it is easy to cause gas detectors to malfunction. For example, when the detector is installed without proper grounding treatment, electromagnetic interference and static electricity cannot be eliminated, and it is prone to failure and even accidents over time.
Third, lack of maintenance
During the detection process of the gas detector, the probe needs to be directly exposed to the environment, so it is inevitable that it will come into contact with some dust and polluting gases in the environment. These substances will cause different degrees of damage to the detector and the probe. As a result, the detector has a large error or even no detection during detection. Therefore, it is necessary to properly maintain the gas detector, otherwise it will also cause various damages and failures to the detector.
Fourth, dismantling without permission
Many people have a certain degree of understanding of circuit maintenance, so when there is a small problem with the detector, they are worried that returning to the factory for maintenance will take time and self-repair. As a result, a small problem "repair" has become a big problem. There are also more, especially portable gas detectors. It is recommended to contact the manufacturer for after-sales service before repairing. If you really do not want to return to the factory, you can repair it under the guidance of the manufacturer's after-sales engineer.
