Particle sensor

The particle sensor is an important component of modern exhaust aftertreatment systems and serves to monitor particle emissions in a vehicle's exhaust system. It measures the concentration of soot particles in the exhaust stream and transmits this information to the engine control unit.

The sensor is used in vehicles with diesel particulate filters (DPF) and supports the monitoring of the particulate filter's function. By continuously monitoring the particulate load, the engine control unit can determine whether the filter is working correctly or whether regeneration is required.

Particle sensors typically operate on an electrical or thermal measurement principle. They detect changes in electrical conductivity or temperature caused by accumulated soot particles in the sensor area. This data is then transmitted to the control unit, which uses it to assess the condition of the particulate filter.

The sensors consist of heat-resistant materials and electronic measuring components designed for use in the hot and chemically stressed environment of the exhaust system. They must withstand high temperatures, exhaust pressure, and strong temperature fluctuations.

A faulty particulate sensor can lead to error messages in the engine control unit, reduced engine performance, or problems with exhaust gas purification. In many cases, the regeneration of the diesel particulate filter can also be disrupted.

In this category, you'll find particle sensors for numerous vehicle makes and models, available in perfect original equipment manufacturer (OEM) quality or as high-quality aftermarket alternatives.
