With the arrival of the flood season, there will often be heavy rain and strong winds, and waterlogging and flooding will also occur from time to time. In the face of heavy rain, how to prevent water ingress in gas detectors? Can the instrument still work normally after water ingress?
What are the hazards of water ingress in gas detectors?
Gas detectors are precision instruments for detecting the leakage concentration of flammable gases or toxic and harmful gases. They can work 24 hours a day. Once the gas leakage concentration reaches or exceeds the preset value, the alarm will immediately send out an audible and visual alarm signal to remind people to take emergency measures. Therefore, consumers should be careful during installation and use 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 rainfall or heavy rainfall increases the possibility of flood disasters, and will also have varying degrees of impact on the normal operation of gas detection equipment. In particular, when there is excessive rainfall and backflow, or improper installation, gas detectors installed outdoors or inside the corridor are prone to water ingress and immersion, which affects their normal detection work.
Gas detector short circuit caused by water inflow: If the gas detector is exposed to rain for a long time or the glass cover of the gas alarm is not tightened in place after opening, rainwater will flow into the instrument. If the gas alarm is not powered off, it will cause a short circuit on the circuit board, affecting its normal operation.
Corrosion and damage to internal components of the instrument: Gas detectors should be kept away from moisture as much as possible during normal detection work. Long-term rainy weather can easily make the instrument damp, which may cause the equipment to rust. If the glass cover of the instrument is not tightened in place after opening, or rain splashes into the detector instrument panel or the inside of the instrument, it will affect the normal operation of the gas detector. If the instrument is soaked for a long time, it will cause the internal circuit board to mold, the chip inside the sensor to be scrapped, the pressure diaphragm to be damaged, the signal board to be corroded and damaged, etc., and it cannot be used normally.
Slow detection response and shortened service life: In a long-term humid environment, the damp gas detector will become “sluggish”, affecting its detection speed, accuracy and stability. Even if it can be detected normally, its service life will be shortened accordingly.
Instrument shell corrosion: Long-term exposure to rainwater erosion, the shell of the gas detector is prone to corrosion, which causes the gas detector to wear and become thinner, cracks, affect its accuracy and sensitivity, and cause damage.
How to prevent water from entering the gas detector?
Install a rain cover: Install a rain cover on the gas detector, which can effectively reduce the erosion of rainwater leakage on the gas detector on rainy days, effectively avoid water damage to the instrument, and extend the service life.
Reinforce the glass cover: The glass cover of the gas detector is not tightened in place. When there is no liquid infiltration inside, just tighten it. However, if liquid has infiltrated the glass cover, the gas detector needs to be stopped 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 higher, due to special weather and manual operation errors, water ingress and immersion of the instrument often occur. Consumers should do a good job of gas detector maintenance, and should conduct timely inspections during use. Do not operate by yourself if abnormalities are found. Contact professionals or return to the factory for repair in time.
Chicheng Electric’s gas detectors all have a high level of protection, and some instruments have a protection level of up to IP67, which can adapt to a variety of harsh environments. After the gas detector is installed and used normally, subsequent regular inspections and maintenance are also necessary, which can greatly extend the service life of the gas detector. Therefore, it is very important to choose a manufacturer with reliable quality, advanced performance and good service!
