SHT21
Humidity Sensor – AEC-Q100
(AEC-Q100 automotive standard) reliability confirmed again |
| |
 Sensirion’s
new SHT21 humidity and temperature sensor has now been qualified in
accordance with the AEC-Q100 automotive standard. This confirms the
outstanding reliability, stability and robustness of the sensor, which
has been in regular production since April 2010. Successful AEC-Q100
(AEC-Q100 automotive standard) qualification is remarkable in the sense that humidity sensors, unlike
fully encapsulated electronic components, are constantly exposed to
their surroundings and sensitive to ambient conditions. During the
qualification process, the SHT21 was put through the series of tests
specified by AEC-Q100 (AEC-Q100 automotive standard). In the High Temperature Operating Lifetime (HTOL)
test, the sensor was operated at 125°C for 1000 hours to test its aging
characteristics. The 96-hour Unbiased Highly Accelerated Stress Test (UHST)
at 130°C and 85% relative humidity confirmed the sensor’s stress
resistance. Furthermore, the package was tested in the Temperature
Cycling (TC) test with 1000 cycles between -50°C and +150°C, which
measures the compatibility of the packaging material with the chip and
the substrate. The series concluded with the Electrostatic Discharge (ESD)
and Electromagnetic Compatibility (EMC) tests, which indicate the
robustness of the sensor with regard to these two parameters. The SHT21
humidity sensor passed all of the tests ... |

New RoaDyn® S615 System 2000 6-component
Wheel Force Transducer with Characteristics Optimized for Small and
Light Cars |
| |
 Kistler:
In addition to engine and air resistance, the key factors in the
development of vehicles with reduced fuel consumption are weight and
rolling resistance. The new RoaDyn S615 is a wheel force transducer
tailored to this car of the future. Reduced vehicle masses and narrower
tires allow further reduction of the weight of the CFRP (carbon fiber
reinforced plastic) components of the transducer. It is optimized for
recording load spectra for durability, vehicle dynamics and power train
investigations. Design of the RoaDyn S615 is based on a three load cell
concept. Saving one cell and its mounting screws shaves 400 g off the
weight of the established RoaDyn S625 light-weight wheel force
transducer system. There is another potential saving of 400 g available
in the design of the inner part, whose CFRP construction offers a
reduction of up to 20 % compared with the RoaDyn® S625. The optimized
design of the RoaDyn S615 allows a maximum vertical load Fz of
approximately 15 kN. ... |

Hydrogen detector with solid electrolyte
sensor improves fuel cell reliability |
| |
|
The
demands the automobile industry places on hydrogen detectors are
scarcely realisable: they have to be H2-specific, exact, durable and
robust, have short response times and in addition low power consumption.
They are also expected to compensate for temperature fluctuations and
humidity. Now J. Dittrich Elektronic is launching a hydrogen
detector on the market that is capable of meeting these demands, using a
novel electrochemical solid electrolyte sensor. Contrary to an
electrochemical cell, the sensor contains a solid electrolyte instead of
a liquid electrolyte. At the three-phase boundary of the measuring
electrode the hydrogen splits into protons and electrons; the resulting
current flow is proportional to the hydrogen concentration. Since this
reaction takes place at room temperature, the heating systems required
for classic solid electrolyte sensors are not needed. The power input of
this handily sized detector (L65 x W36 x H16 mm) is correspondingly low
at 0.32 watts. It contains no moving parts; silicone, halogen and
sulphuric compounds do not impair its functioning. In addition, it is
neither cross sensitive to HC, H2S, NO, NO2, CO nor to CO2. The sensor
has a fast response time ... |

Tyco Electronics Reluctance Resolvers for
Hybrid Applications |
| |

Tyco
Electronics: New emission legislation and the trend towards energy
efficient transportation support an increased development in the area of
hybrid propulsion for passenger cars. One of the key applications for
improved fuel economy in the hybrid market is the recovery and storage
of energy during the braking phase or regenerative braking. When
braking, the energy of the moving car is converted and stored in the
Li-ion batteries instead of being dissipated through the heating of
braking disks. Upon acceleration of the car, the available electrical
energy is used to help the car speed up by releasing this energy into a
controlled electrical motor. More advanced systems may continuously
propel the cars’ electrical motors. In order to keep the efficiency of
the electrical hybrid motors at a maximum level, the position of the
drive shaft must be continuously monitored. Tyco Electronics has
developed a break-though inductive sensor, known as a “Reluctance
Resolver,” that can help support reduced fuel consumption with in these
new hybrid propulsion systems. The Reluctance Resolver is part of a

Turbocharger speed sensor for high volume
production |
| |
|
New
from Micro-Epsilon is a range of turbocharger speed sensors for
high volume production. The turboSPEED TSSC series of sensors operates
according to the eddy
current principle and so provide several benefits. The sensor is
cast in plastic and has a separate electronics unit, which can be
integrated in the engine compartment separate from the turbocharger.
Speeds of 200 to 400,000rpm can be measured accurately with the sensor.
Due to the complex electronics and special linearisation, the sensor can
measure on turbine wheels made from aluminium or titanium. Titanium is
well known as a poor electrical conductor and is therefore generally
difficult to measure. The electronics for each turbine model is
configured and fixed afterwards for high precision. The low cost version
of the sensor meets all necessary requirements for the
automotive industry. The housing is protected to IP67; the
electronics complies with the EMC requirements in the engine
compartment. Different from conventional sensors for turbochargers, the
new sensor does not measure on the shaft between the two turbine wheels,
since these are often no longer accessible with the latest
turbochargers. The turboSPEED TSSC detects the edge of the compressor
wheel on the “cold” side of the turbocharger ... |
