How to Solve the Problem of Gas Detectors Getting Waterlogged in Stormy Weather?

As the flood season approaches, there are often heavy rain and strong wind weather, and situations such as waterlogging and floods also occur from time to time. In the face of heavy rain, how can we prevent gas detectors from getting waterlogged? Can the instrument still work properly after getting waterlogged?

What are the Hazards of a Gas Detector Getting Waterlogged?
A gas detector is a precision instrument for detecting the leakage concentration of combustible or toxic and harmful gases. It can work continuously for 24 hours. Once the gas leakage concentration reaches or exceeds the preset value, the alarm will immediately emit audible and visual alarm signals to remind people to take emergency measures. Therefore, consumers should be careful during the installation and use process to prevent damage to the instrument.
However, during the flood season, consumers should pay special attention to the impact of continuous precipitation on the instrument. The increase in continuous or heavy rainfall increases the likelihood of flood disasters and also has varying degrees of impact on the normal operation of gas detection equipment. Especially when there is excessive rainfall causing backflow or improper installation, gas detectors installed outdoors or inside pipe galleries are prone to waterlogging and immersion, affecting their normal detection work.
Short-circuit due to waterlogging: If the gas detector is exposed to rain for a long time or the glass cover of the gas alarm is not tightened properly after being opened, rainwater will flow into the instrument. If the gas alarm is not powered off, it will also cause a short-circuit in the circuit board, affecting its normal operation.
Corrosion and damage of internal components: During normal detection work, gas detectors should be kept away from moisture as much as possible. Long-term rainy weather can easily make the instrument damp, which is likely to cause equipment corrosion. If the glass cover of the instrument is not tightened properly after being opened, or rainwater splashes into the detector dashboard or the interior of the instrument, it will affect the normal operation of the gas detector. If the instrument is immersed for a long time, it will lead to problems such as moldy internal circuit boards, scrap sensor internal chips, damaged pressure diaphragms, and corroded signal boards, making it unable to be used normally.
Slow detection response and shortened service life: In a long-term humid environment, a damp gas detector will become "slow", affecting its detection speed, accuracy, and stability. Even if it can still detect normally, its service life will be shortened accordingly.
Corrosion of the instrument housing: The shell of the gas detector is easily corroded by long-term rain erosion, resulting in the detector wearing thin and developing cracks, affecting its accuracy and sensitivity and causing damage.

How to Prevent Gas Detectors from Getting Waterlogged?
• Install a rain cover: Installing a rain cover for the gas detector can effectively reduce the erosion of the gas detector by rainwater leakage during rainy days, effectively prevent the instrument from being damaged by waterlogging, and extend its service life.
• Reinforce the glass cover: If the glass cover of the gas detector is not tightened properly and there is no liquid penetration inside, simply tighten it. However, if liquid has already penetrated into the glass cover, the gas detector needs to be stopped immediately and dried quickly. If the calibration data is abnormal after powering on again, it should be repaired as soon as possible.
• Timely inspection and maintenance: Although the protection level of gas detectors generally reaches IP65/IP66 or even higher, due to the influence of special weather and human operation errors, waterlogging and immersion of instruments still occur from time to time. Consumers should do a good job in the maintenance of gas detectors. During the use process, they should conduct timely inspections. If any abnormalities are found, do not operate by yourself. Instead, contact professionals or return the instrument to the factory for repair in a timely manner.

All gas detectors of Chuang’an Electronics have a high protection level, and the protection level of some instruments can reach IP66, which can adapt to a variety of harsh environments. After the installation and normal use of gas detectors, subsequent regular inspections and maintenance are also necessary, which can greatly extend the service life of gas detectors. Therefore, it is very important to choose a manufacturer with reliable quality, advanced performance, and good service!
