The stability of the sensor in a flammable gas detector
Sensors are the core components of gas alarms, and their stability determines the correct measurement and alarm of gas alarms. Stability refers to the ability to maintain its performance unchanged after a period of use. The higher the stability, the better the performance, the more accurate the measurement, the worse the stability, the more likely the performance is to decrease, and the more likely the detection results are to produce deviations.
In addition, the usage environment and exposure time of combustible gas detectors can also affect the stability of the sensor and cause changes. Because there are many unknown factors in the usage environment of gas alarms, especially in mining gas alarms, the usage environment is very harsh, and there may even be gases such as hydrogen sulfide that can poison the sensor, which has a significant impact on the performance of
the instrument. Therefore, in order for the sensor to have good stability, it must have strong environmental adaptability.
Therefore, when choosing a combustible gas detector, users must consider the stability of the sensor and conduct a thorough investigation and analysis of its usage environment in advance. Based on the actual environmental conditions, appropriate sensors should be selected or appropriate measures should be taken to reduce the impact of the environment.
The stability of combustible gas detector sensors has a limit, and after exceeding the specified service life, they must be recalibrated to determine whether the performance of the sensor has changed. In some special environments where sensors are required to work for a long time and cannot be easily replaced or calibrated, it is necessary to choose sensors with very high stability and the ability to withstand harsh environments for a long time.
