SGAS707

Gas sensors are devices that detect or measure the concentration of one or more gases in the atmosphere. SGAS707 is one type of high-performance gas sensor developed by XYP. It adopts the semiconductor sensing technology and can measure the oxygen concentration range, obtaining highly accurate signals. This article will discuss the application field and working principle of SGAS707.

Application field

SGAS707 can be widely used in medical, industrial, and environmental fields. Its main application areas include medical oxygen monitors, fuel cell systems, and industrial process control. In medical fields, SGAS707 is mainly used in medical oxygen monitors, such as ventilators and patient monitors. This sensor can accurately measure the concentration of oxygen in the air, providing medical personnel with timely and accurate data and ensuring the safety of the patient. In the fuel cell system, SGAS707 can measure the amount of oxygen in the fuel cell, which can help to adjust the system parameters and optimize the fuel cell efficiency.

In the industrial process control, SGAS707 can measure the oxygen concentration in the working environment, providing useful information for safety monitoring. In environmental monitoring, SGAS707 can measure the amount of oxygen in the air to help monitor air quality and ensure the safety of the environment.

Working Principle

SGAS707 gas sensor consists of a semiconductor element, a heater, an oxygen inhibitor, and an electronic circuit. The operating principle of the sensor is based on the interaction between oxygen and the semiconductor element. The electronic circuit sends a heating current to make the semiconductor element warm. Since the semiconductor material can adsorb oxygen, when there is oxygen in the air, the concentration of adsorbed oxygen molecules increases, resulting in a decrease in the electrical resistance of the semiconductor element. With the increasing concentration of oxygen molecules, the resistance of the semiconductor element decreases accordingly.

The oxygen inhibitor installed at the front end of the sensor can inhibit the diffusion of oxygen molecule into the sensor, so that SGAS707 only measures the oxygen concentration in the environment but not the concentration of other kinds of gases. And the electronic circuit can convert the detected resistance value of the semiconductor element into an oxygen concentration value after calibration.

Conclusion
