NTC series use the temperature elements of the ceramic sensor technology for high temperature applications up to > 1000°C. This temperature element is located at the tip of the sensor and measures the temperature, this is passed on in the sensor as a resistance signal. With an NTC, the resistance decreases as the temperature rises.

The NOx sensor is part of the NOx reduction aftertreatment system used in diesel vehicles with urea based SCR systems. The sensor located upstream of the SCR catalyst directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection. The NOx sensor downstream of the SCR catalyst is used to monitor the performance of the catalyst. Accurate NOx measurement is in high demand to comply with increasingly strict NOx emissions regulations. The NOx sensor is also capable of measuring O2 concentration, just like a wide range air-fuel sensor.

Thermocouples to measure the temperature of exhaust gases are a key element of modern engine management. Measuring the temperature of exhaust gas can provide an important input into system algorithms to improve efficiency, reduce pollutants and extend engine life.

PTC EGT sensor series use the temperature elements of the platinum sensor technology for high temperature applications up to > 1000°C. This temperature element is located at the tip of the sensor and measures the temperature, this is passed on in the sensor as a resistance signal. The resistance signal changes here as the temperature rises.
