Product highlights

NTC sensor elements for temperature measurement up to 650 °C

The EPCOS NTC sensor element designed for measuring temperatures up to 650 °C is based on a high-temperature ceramic sensor element that is connected to a metallized aluminum oxide rod and then glass-encapsulated. The sensor element offers high-precision measurement with a temperature tolerance of about ±1 K at 200 °C. The component obtains its particular ruggedness from the glass encapsulation. The sensor is available optionally with wires welded to the aluminum-oxide rod. The component is 16 mm long and the glass encapsulation has a diameter of 2 mm.

The high-temperature sensor is qualified to AEC-Q200 and designed for use in especially demanding automotive electronics applications, for example, in exhaust gas recirculation systems. These are used mainly on diesel engines to reduce excess oxygen in the combustion gas and thereby minimize the formation of nitrogen oxides at high combustion temperatures. In the recirculation systems the NTC sensors measure the temperature of the exhaust gas and thus help to protect the engine against overheating – in particular, the cylinder head and valve seats.

In e-mobility applications the new sensors are able to monitor the temperature of fuel cells that are used in electric vehicle drive systems for the direct generation of electrical energy from hydrogen. Applications can also be found in household appliances, for example in self-cleaning ovens that operate on the pyrolytic principle. These work by heating the oven interior to a temperature of about 500 °C which breaks down the long-chain molecules of the food residues and reduces them largely to gas and ash. The necessary temperature is regulated and stabilized by the NTC sensors.

Precise angular rate measurement with inertial sensors

The Tronics GYPRO3300 MEMS gyro sets a benchmark in angular rate measurement. It is factory-calibrated and temperature-compensated by means of an integral temperature sensor, enabling it to operate with stability and precision over a wide temperature range. It delivers a 24-bit signal via a serial peripheral interface (SPI), and the bias instability and angle deviation exhibit excellent values of just 0.8°/h and 0.15°/√h, respectively. These values far exceed the requirements of the automotive industry.

With its excellent performance in a single-chip solution, the Tronics GYPRO3300 qualifies as best-in-class and also offers compact dimensions of just 19.6 mm x 11.5 mm x 3.7 mm. This MEMS gyro is therefore suitable for extremely demanding applications such as the stabilization of oil drilling platforms, aircraft navigation, attitude and heading reference systems (AHRS), as well as advanced driver assistance systems (ADAS). The compact MEMS inertial sensors are based on the Tronics Magellan process technology that offers a new level of integration, enabling the measurement of as many as 6 axes in a single chip.

World's smallest 6-axis sensor

The InvenSense portfolio includes automotive-qualified inertial sensors and gyroscopes for navigation, telematics, autonomous driving, ADAS, in-cabin and safety applications. The IAM-20680 is an integrated 6-axis high-performance inertial sensor and gyroscope with excellent temperature stability. It also features the least noise of commonly available 6-axis sensors for in-cabin applications such as navigation. The IAM-20680 is the smallest sensor of its kind on the market. The IAM-20380 (3-axis gyroscope) and the IAM-20381 (3-axis inertial sensor) are pin, footprint, register and software compatible with the IAM-20680.

TMR angle sensors for highest precision and reliability

TDK TMR sensors can be used in systems that meet the requirements of ASIL-D (Automotive Safety Integrity Level D, the highest safety requirements) according to the ISO 26262 standard. They are can be used up to therefore suitable for such safety-related applications as electric assisted steering and braking. A further outstanding feature of the TMR sensors is their high angle precision, which is adjustable. Depending on the magnetic field strength, residual angle errors of less than 0.2 degrees can be achieved over the vehicle service life (17 years) and a temperature range (-40°C to 175°C). The current TDK TMR sensor product range covers simple angle sensors, rotational speed sensors and linear sensors for power steering systems, wipers, clutch and gearbox positioners, pedals and throttle valves and many other applications.
