Committed to making vehicles safer, high-tech and greener, the Automotive Industry is always improving its techniques and production methods aiming at a better cost, control, and production results.


Future generations of vehicles depend on modern emission control systems and hybrid technologies, while electromobility is becoming a key technology for the next cars.

Facing new challenges will require sophisticated technology and Process Control plays a significant role here, as precise data measurement. Precision is required even under extreme conditions, such as high-temperature variations, harsh environments, and severe mechanical stress.

Platinum sensors guarantee the precision and reliability you need for your applications. With their help, you achieve precisely and constantly measurement data with little drift even over long periods and range from –40°C to 1050°C. Outstanding chemical and mechanical stability and resistance to moisture, climate and other environmental factors, make measurements reproducible over many tens of thousands of cycles, thereby ensuring the necessary safety in continuous operation.

Because of this unique combination, we are your first choice for the development of reliable and innovative solutions. We work with you to find the best solution for your needs, and we support you from the idea to design to technical support in series production.

Treatment of exhaust gases


Catalytic converter


A catalytic converter is an emissions control device that converts toxic gases and pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are used with internal combustion engines fueled by either petrol (gasoline) or diesel—including lean-burn engines as well as kerosene heaters and stoves.

A couple items of temperature information are needed in order to produce the optimum exhaust treatment, principally in diesel exhaust systems. For this application, Sensor Technology has developed special probes that cover the complete temperature range up to 1000°C.

In addition, our temperature sensors are also used as component protection (overheating protection).

Temperature sensor design

The high-temperature measuring elements are available in differing lengths for temperatures of up to 1050°C , value that is seldom required in diesel technology where temperatures of up to 750°C are customary.

There are two elements, 24 mm long type HA 2421 and the 4 mm long type HA 421. The longer version is suitable for open installation due to its very short response time, while the short version is a very robust model intended for installation in closed areas.
