How long is the service life of the gas detector and its operating procedures
A gas detector mainly includes electronic components and sensor heads. Taking the FG100 gas detector as an example, the average failure interval of electronic components is at least 30 years, but the sensor head is definitely not that long.
The service life of gas sensors depends on multiple factors: the technical principles used, the surrounding environmental conditions, and whether there is frequent presence of target gases. In terms of combustible gas detection, sensors using infrared detection technology will have a lifespan 2-3 times longer than sensors based on catalytic combustion principles, and infrared sensors will not lose their lifespan due to exposure to continuous or high concentrations of combustible gases. When there is a target gas around the catalytic combustion principle sensor for a long time, its lifespan will be shortened. If there are target gases in the surrounding environment of the same electrochemical sensor, its lifespan will also be shortened.
Another factor to consider is environmental temperature and humidity. If the temperature exceeds the normal operating range and the humidity is too high or too low, the lifespan of the sensor will also be shortened.
Although the specifications of the gas detector specify the lifespan of the sensor, the sensor probe is like a tire on a car and depends on factors such as road surface, mileage, and temperature. Generally speaking, the service life of electrochemical and catalytic combustion principle sensors is 2-3 years, while that of infrared principle sensors is about 5 years.
How to maintain a gas detector:
1. Whole machine inspection: The detector should be checked regularly, and its signal current is DC4mA in clean air.
2. Sensor maintenance: Generally, re inspection and calibration are required after six months to one year of installation and use, and a testing report should be issued by the testing party.
3. When the sensor of the gas detector loses sensitivity, it needs to be replaced. Regular calibration will determine whether the sensor has failed. When the calibration value does not reach the standard gas value, the sensor needs to be replaced.
