Oxygen Sensor
  • The oxygen sensor is a current source, and the current depends on the oxygen reaction rate (Faraday's law). The voltage can be measured by connecting a known resistance. If the oxygen flow through the sensor is completely limited diffusion, this electrical signal can reflect the oxygen concentration.

TAG:  Oxygen Sensor Bosean gas  gas sensor oem
  • The life of the sensor is 2 years, and it can directly measure oxygen in the concentration range of 0-25%. The pins on the bottom of the sensor can be directly connected to a PCB board. This sensor is suitable for portable or fixed safety devices.


Output model

  • The operation of the oxygen sensor is simple, which is achieved by connecting a low resistance resistor to generate a voltage signal. The maximum voltage signal must not exceed 100mV.

  • In most cases, a 100Ω resistor is sufficient. In general, the higher the resistance value, the longer the response time of the sensor. It is important to choose a suitable range of resistors to eliminate changes and long-term drift between the sensors due to differences in output current and temperature.


Linear relationship

  • The percentage concentration of oxygen in both curves is in the range of 0-20.9%, which reflects the relationship between the signal output during the calibration in the air and the oxygen concentration. The maximum deviation occurs when the oxygen concentration is 10%, and the output value is 0.5% lower than the standard value. In most cases, this deviation is negligible, but if necessary, digital technology can be used to compensate.


Carrier gas impact
  • In most cases, the oxygen sensor can be calibrated in ambient air, but if it is a high-concentration gas other than air, the carrier gas (that is, very little mixed oxygen) will have a greater impact on the output signal.
  • The output signal depends on the oxygen diffusion rate, which depends on the molecular weight of the carrier gas (Graham's law). The dry air contains 20.95% oxygen, and the remaining nitrogen with a molecular weight of 28, so when the carrier gas used is a gas with a molecular weight greater than that of nitrogen, the output signal will be greatly affected.
