VQ547TS

Gas sensors are used for the detection of various gases. With the development of technology, more and more gases can be detected and different types of gas sensors are used in different fields. The VQ547TS gas sensor is a new type of gas sensor developed to detect nitrogen oxides (NOx). It is widely used in industrial fields such as exhaust emission testing, industrial process control, and biomedical analysis, as well as in automotive and agricultural industry.

The VQ547TS gas sensor is a solid-state gas sensor using metal oxide semiconductor principle. As a solid-state gas detector, it consists of a catalytic section and a sensing section. The catalytic section is made of metal oxides such as tungsten trioxide, nickel oxide, manganese dioxide, and so on, and the sensing section is made of zirconia ceramic coated with platinum black. The two sections are held together and sealed in a stainless steel housing. The catalyst reacts with the gas under detection and heats up while the sensing section senses the change in temperature and produces a signal output.

When working, the VQ547TS gas sensor is exposed to the gas under detection. The gas reacts with the catalytic section, thus producing heat, which is then sensed by the sensing section. The sensing section produces a voltage that is proportional to the amount of heat generated. This voltage is then measured to determine the concentration of the target gas.

The VQ547TS gas sensor has a wide range of applications in various fields. It can be used for exhaust emission testing, industrial process control, air quality monitoring, medical diagnosis, and automotive sensing applications. It is also used in agricultural applications for soil gas analysis and in ocean studies for monitoring seawater chemistry. The VQ547TS gas sensor is able to measure nitrogen oxides (NOx) concentrations up to 20 ppm with a resolution of 0.05 ppm.

In conclusion, the VQ547TS gas sensor is a highly sensitive and reliable detector that is used for the detection of nitrogen oxides. It can be used in a wide range of applications such as exhaust emission testing, industrial process control, air quality monitoring, medical diagnosis, automotive sensing, and agricultural and ocean studies. With its accuracy and precision, the VQ547TS gas sensor is an invaluable tool for detecting traces of nitrogen oxides in the environment.
