What are the common causes of combustible gas detectors getting damaged?
The combustible gas detector is a gas detection equipment that detects the leak concentration of combustible gases. It mainly uses sensors to detect the type, composition and content of combustible gases present in the environment. However, many factors may affect the use of combustible gas detectors and cause damage during use. So what are the common causes of damage to combustible gas detectors?
Common causes of damage to combustible gas detectors:
1. Improper use by the user (such as excessive temperature)
When using the detector, the user installs air conditioning and heating equipment close to the combustible gas detector. When using air conditioning and heating equipment, if the cold or warm air flows directly through the combustible gas alarm, it may cause the gas alarm to The resistivity of the platinum wire changes and errors occur. Therefore, the gas alarm should be kept away from air conditioners and heating equipment to avoid malfunctions caused by improper setting. Users should also pay attention to preventing electromagnetic interference when using a reputable combustible gas detector.
2. Irregularities in the construction process (such as lack of good grounding during construction)
Irregularities in the construction process will cause combustible gas detectors to detect faults during use. If the detector is not located near equipment prone to leaking combustible gas, the leaked combustible gas cannot fully diffuse to the vicinity of the detector, making it impossible for the detector to detect the danger of leakage in time. The combustible gas detector cannot be grounded and cannot eliminate electromagnetic interference, which will inevitably affect the voltage and cause inaccurate detection data.
3. Improper maintenance and upkeep in the later period (such as prolonged contact with chemical substances)
The combustible gas detector must detect combustible gas information, so it is inevitable that various polluting gases and dust in the environment will enter the detector. The damage to the working conditions of the detector is an objective reality. Combustible gas detectors The working environment is relatively harsh, and many of them are installed outdoors. Improper maintenance will lead to errors in gas alarm detection or no detection.
4. Other major sudden accidents (such as short circuit, open circuit, etc.)
The reason why it is recommended that each enterprise set up a special maintenance department for combustible gas detectors is because combustible gas detectors play important responsibilities and must avoid accidents. For example, combustible gas detectors and terminal blocks are located in areas that are prone to collision or easy Water intrusion may cause electrical circuit breakage or short circuit, etc. Such sudden accidents may cause detection failure, which is also an important loss factor.
