What aspects should be paid special attention to during the use of combustible gas alarm?

Publication Date:2024/04/19

Combustible gas alarm, as the 1 important safety equipment, every detail in the use process is related to the safety of people's lives and property. In order to ensure that the combustible gas alarm can play its due role, we must pay enough attention to its use. So do you know what you need to pay special attention to when using Combustible Gas Alarm ? The following is a brief introduction by yiyuntian electronics:


 combustible gas alarm


during the use of combustible gas alarm, special attention should be paid to the following aspects:


1.


Combustible gas alarms should be installed in areas of high risk of potential combustible gas leakage, such as near gas storage tanks, process pipe connections, etc. At the same time, considering the diffusivity of the gas, the combustible gas alarm should be installed in a location with good air circulation, and avoid installation in dead corners or poorly ventilated places to ensure that it can detect gas leaks in time.


2. Use environment


Customers should understand the temperature, humidity and pressure in their own working environment before purchasing, ensure that the purchased combustible gas alarm can be used normally. Generally speaking, the temperature used by the gas detector is between -20 ℃ and -50 ℃, the humidity is 10%-95% RH without condensation, and the pressure is 80-120kpa. If the sensor is used beyond the range, it will damage the sensor.


3. Verification period


Combustible gas alarm in use after a period of time, the detection results often have the phenomenon of error. To ensure the accuracy of the test results, it is necessary to regularly zero the combustible gas alarm. The normal calibration cycle does not exceed one year. If it is used frequently or in a relatively harsh environment, the calibration cycle needs to be shortened.


4. Routine maintenance


The user should calibrate the combustible gas alarm regularly, ensure its accuracy and sensitivity. At the same time, check whether the key components such as the power supply and sensor of the combustible gas alarm are working normally, and replace the damaged or aging parts in time to prevent false alarms or omissions due to equipment failure.


5. Alarm threshold setting


Setting the threshold of the combustible gas alarm too low may cause frequent false alarms, affect work efficiency, and set too high may be underreported, can not find the potential danger in time. Therefore, the user should reasonably set the alarm threshold according to the actual working environment and gas concentration level to ensure the effectiveness and reliability of the combustible gas alarm.


6. Avoid overrange use


the range of combustible gas alarm is 0-100% LEL, if the gas concentration in the detection environment is higher than 100 LEL, it will cause the combustible gas alarm to overrange. At this time, the gas sensor needs to be calibrated again before it can be used normally again.


To sum up, it is some aspects that need special attention during the use of combustible gas alarms.We only do a good job of the correct use and maintenance, in order to ensure that the combustible gas alarm to maintain normal work, so as to provide effective protection for the safety of people's lives and property.
