Oxygen sensors are used for automotive emission control, industrial process control, and medical devices.
1, automotive emissions control: oxygen sensor plays a key role in the exhaust system of the car. It monitors the oxygen content in the exhaust gases emitted by the engine and feeds the information back to the vehicle's control unit. This allows the vehicle to adjust the fuel mixing ratio in real time to ensure maximum engine combustion efficiency and minimize emissions.
2, industrial process control: In some industrial applications, oxygen sensors are used to monitor and control the oxygen concentration in production processes. For example, in the refining, steel, chemical and other industries, oxygen sensors can be used to monitor the oxygen level in the reactor to ensure that the reaction is carried out effectively.
3, medical equipment: oxygen sensors are also widely used in medical equipment, such as ventilators, anesthesia machines and oximeters. They are used to monitor the patient's respiratory oxygen level or oxygen saturation in the blood. This is important to ensure that the patient's respiratory and blood oxygen levels are in the normal range.
Precautions for using oxygen sensors
1. Installation location: When installing an oxygen sensor, make sure it is placed in the proper location. Position selection should consider the sensor can be fully exposed to the gas environment to be measured, to avoid blocking or interference. At the same time, ensure that the sensor is firmly installed to avoid displacement or damage.
2. Cleaning and maintenance: Regular cleaning and maintenance of the oxygen sensor is critical to its proper operation and accuracy. Follow the manufacturer's recommendations for regular inspection and cleaning of the sensor to remove dust and dirt buildup and to ensure good contact with the sensor connector.
3. Calibration and Verification: Regular calibration and verification are necessary to ensure the accuracy of the oxygen sensor. The calibration process compares the sensor to a standard of known oxygen concentration to correct for any deviations. Calibration verifies that the sensor's accuracy and performance meets specifications.
