Gas sensors are a major category of chemical sensors. From working principle and characteristic analysis to measurement technology, from materials used to manufacturing processes, from detection objects to application fields, independent classification standards can be formed, giving rise to a complex and intricate classification system. Especially in the issue of classification standards, there is still no unified system, making it difficult to conduct strict systematic classification. Next, let's learn about the main characteristics of gas sensors:

1. Stability

Stability refers to the stability of the sensor's basic response throughout the entire working time, which depends on zero drift and interval drift. Zero drift refers to the change in sensor output response throughout the entire working time in the absence of a target gas. Interval drift refers to the change in output response of a sensor continuously placed in a target gas, manifested as a decrease in the sensor output signal during the working time. In an ideal scenario, a sensor would have an annual zero drift of less than 10% under continuous operating conditions.

2. Sensitivity

Sensitivity refers to the ratio of the change in sensor output to the change in the measured input, which mainly depends on the technology used in the sensor structure. The design principles of most gas sensors adopt biochemistry, electrochemistry, physics, and optics. The first consideration is to choose a sensitive technology that has sufficient sensitivity for detecting the percentage of TLV threshold old limit value or LEL lower explosive limit of the target gas.

3. Selective

Selectivity is also known as cross sensitivity. It can be determined by measuring the sensor response generated by a certain concentration of interfering gas. This response is equivalent to the sensor response generated by a certain concentration of target gas. This characteristic is very important in applications that track multiple gases, as cross sensitivity reduces measurement repeatability and reliability. Ideal sensors should have high sensitivity and selectivity.

4. Corrosion resistance

Corrosion resistance refers to the ability of a sensor to be exposed to high volume fraction target gases. When a large amount of gas leaks, the probe should be able to withstand 10-20 times the expected gas volume fraction. Under normal working conditions, sensor drift and zero point correction values should be minimized as much as possible.

The basic characteristics of gas sensors, such as sensitivity, selectivity, and stability, are mainly determined by the selection of materials. Select appropriate materials and develop new materials to achieve optimal sensitivity characteristics of gas sensors.
