Oxygen Sensors and the Role of Advanced Heating Elements
To ensure normal operation, the oxygen sensor must reach a working temperature of 300–400 °C. Without a heating device, the sensor can only rely on hot exhaust gases to warm up, which will delay its startup and result in higher emissions during cold starts. Integrated heating elements, such as ceramic heating chips, solve this problem. They can provide rapid and reliable heating at the moment of engine startup.
Introduction: What is an Oxygen Sensor? An oxygen sensor is a key device for measuring the oxygen concentration in exhaust gas. At its core,
