Sensors for Automotive Applications

Temperature sensing and control are among the most important and well­established functions in automotive electronics. In automotive electronics they are found especially in climate control and powertrain applications.

In recent years we have introduced a great variety of new sensors and sensor systems to the automotive market and continuously develop innovative products to meet customers’ requirements.

EPCOS sensors stand out for excellent measuring accuracy and long­term stability. Advanced technologies allow cost­efficient and large­scale production of reliable sensors. Thus, we are able to offer sensors overmolded with plastic or encapsulated in specific materials for reliable use in adverse environments for a large range of tempera­tures. They can be delivered in numerous shapes and with a wide variety of cable and connector geometries.

If standard types do not match the purpose – we can also supply application­specific sensors with customized parameters.

Our design centers and plants for sensor products – in Berlin, Germany, Deutschlandsberg, Austria, Zhuhai, China, and Batam, Indonesia – are certified to ISO 9001:2008, ISO/TS 16949:2009 and ISO 14001:2004.

With our comprehensive sensor portfolio we help automotive manufacturers make their products safer, more convenient to use and more energy­efficient.

This product brief can only present a selection of our continuously growing portfolio of both temperature and pressure sensor products.

In addition to the presented temperature sensors, we also offer an extensive range of pressure sensors that are suitable for automotive industry. For example, pressure sensors can be used to measure the pressure of various media and thus support engine management and safety systems. Such sensors are needed to achieve precise engine control for low fuel consumption and to enable exhaust gas treatment for a reduction of harmful emissions.

Climate control

Effective air­conditioning helps drivers keep a cool head in the most tricky situations and minimizes the stress on passengers. The control of the air­conditioning system can be based on the temperature at the evaporator or in the air streams of every outlet carrying air to the feet or body of the passengers.

One effect that temperature sensors are unable to detect is the warmth of direct sunlight that passengers feel on their skin. In this case, solar sensors can be used to evaluate the intensity and in many cases the direction of incoming solar rays.

Thermal management and automatic transmissions

Temperature sensors in xEV appli­cations must cover a wide range of operating temperatures, high shock resistance and vibrational strength, high reliability and long term stability – even under harsh operating con ditions. They are used to measure the temperature of the battery in both cell and coolant as well as motor and transmission oils. For these applications EPCOS offers sensors with a high tempera­ture range up to 250 °C and with different mounting solutions to meet a wide variety of demands.
