H2 sensor easy detection of hydrogen
With the development of science and technology, sensor technology has become an indispensable part of modern industry and daily life. Among them, H2 sensor, as an important sensor, has been widely used in chemical industry, energy, environmental protection and other fields. So, what is the working principle of hydrogen sensor? And what advantages does it have? Next, we will come together to understand.
Principle of operation of the H2 sensor
The Hydrogen Gas Sensor FS02501 produced by Fosensor uses the electrochemical working principle and consists of an anode and a cathode separated by a thin layer of electrolyte. When hydrogen passes through an electrolyte, a reversible chemical reaction occurs, producing an electric current proportional to the concentration of the gas. Electrochemical hydrogen sensors require very little power to operate and their power consumption is the lowest of all sensor types. The electrochemical hydrogen sensor has the characteristics of high sensitivity, short reaction time, good reproducibility after calibration, good linearity, stable zero point, and relatively low cross-sensitivity. They are very useful in safety and process control applications. A major disadvantage of electrochemical hydrogen sensors is that sensitivity decreases over time due to loss of catalytic surface.
Advantages of H2 sensor
1. High sensitivity: Hydrogen sensors are characterized by high sensitivity and fast response, capable of detecting low concentrations of hydrogen, and the response time is generally within a few seconds.
2. Strong anti-interference ability: Dexer hydrogen sensor has the advantage of strong anti-interference ability, can effectively avoid the interference of other gases, to ensure the accuracy of measurement.
3. Small size: The hydrogen sensor is small in size, easy to carry and use, and can be detected anytime and anywhere.
Good stability: hydrogen sensor has very good stability, long service life, not easy to fail, simple maintenance.
Application of H2 Sensor
Hydrogen sensors are widely used in the fields of chemical industry, energy and environmental protection. For example, in the field of energy, hydrogen sensors can be used to detect the leakage of hydrogen to ensure the safety of energy; in the field of environmental protection, hydrogen sensors can be used to detect the concentration of hydrogen in the body of water and determine the degree of pollution of the body of water.
In conclusion, as an important sensor, H2 sensor has many advantages and wide applications. In the future, with the continuous progress of science and technology, the performance of hydrogen sensors will continue to improve, bringing more convenience and safety to industry and daily life.
