Protect engine components, reduce emissions of harmful gases

Turbocharger, diesel particulate filter and catalytic converter, 3-way, all of these parts must be protected from temperatures of exhaust gas to be excessive. It is the role of the temperature sensors. With a vehicle on three equipped in the world and 60% of the market share in 1st monte, NTK is the world leader in the manufacture of temperature sensors of exhaust gas.

What good is a temperature sensor of exhaust gases ?

The sensing element of the sensor consists of a ceramic technique sensitive to variations in temperature. The sensing element is a NTC type (Negative Temperature Coefficient, in English NTC, Negative Temperature Coefficient). It is a semiconductor whose resistance decreases logarithmic with the increase of the temperature.

The temperature sensors are sensors which convert a temperature in its field of operation, to an electrical signal.

The latest generation of temperature sensors of exhaust gas NTK is capable of measuring temperatures from -40°C up to 900°C. They are located in :

• before the turbocharger
• after the turbocharger
• before and after the particulate filter
• before and after the catalyst three-way

• What is a temperature sensor in the exhaust line ?

  The temperature sensors of exhaust gas are essential to modern vehicles because they protect the items that are present in the flow of hot exhaust gases from overheating critical. The engines have become increasingly clean, affordable, and at the same time more powerful
