Light-section sensors open new
application possibilities |
| |
 With
the new LRS 36 and LPS 36 light-section sensors, Leuze electronic
has realized sensors for economical object detection over long
measurement ranges from 200 to 800 mm. The transmitters and receivers
are contained in an easy-to-install unit with very compact housing
design. Line range sensors (LRS) detect the presence of objects through
scanning, similar to light barriers or laser scanners. By comparison,
line profile sensors (LPS) measure the dimensions or position of static
or moving objects. Where previously complex sensor solutions, sensor
combinations or additional evaluation units were necessary, the new LRS
36 and LPS 36 light-section sensors from Leuze electronic, with their
800 mm measurement range, open new fields of application. ... |

 In
its latest brochure, measurement technology specialist Micro-Epsilon
is presenting new possibilities for displacement, profile and
temperature measurement of wind turbine systems. The brochure provides
details on the specific benefits associated with the use of sensors in

Fail-safe oxygen measuring system
increases the efficiency of pellet heaters |
| |
 Increasing
numbers of households are now turning to wood or pellet heaters for
their central heating systems. Using the fail-safe MF010-O-LC oxygen
measuring system from J. Dittrich Elektronic it is possible to
determine the residual oxygen content in furnace exhaust gas. With the
help of a controller, the excess air necessary for reasons of safety can
be minimised and combustion optimised, thereby increasing efficiency.
Emission values in the exhaust gas fall. In addition, it is possible to
compensate for fluctuations in the calorific value of the fuel or in the
fuel supply. Contrary to a lambda probe which measures the relative
oxygen content, the extremely robust oxygen measuring system determines
the absolute content, i.e. the oxygen partial pressure in the exhaust
gas. For this reason, fluctuations in air pressure, humidity and
temperature have no influence on the accuracy of the measurement. ... |

SENSOR+TEST 2010: Sensor, Measuring, and
Testing Technology to the Point |
| |
|
AMA
Association for Sensor Technology.: From the 18th to the 20th of May
2010, the 17th International Trade Fair for Sensorics, Measuring, and
Testing Technology will be held on the Nürnberg exhibition grounds.
Reflecting the growing economic significance of these cross-cutting
thematic areas, the AMA Association counts with about 500 exhibitors
despite the recent economic downturn in the major supplied industries.
The great demand for innovation by the users is seen as a special
challenge for supplier presence. Focus: Energy Efficiency: For the first
time, this year the trade fair will be held under a motto. Reflecting
the worldwide discussion, the Exhibitor Committee of the SENSOR+TEST
and the Executive Board of the AMA Association have decided to focus on
energy efficiency. Sensors in devices and machines, in plants, buildings,
and cars make it possible to find and maintain energy-optimized
operating modes. And it is measuring and testing technology which
provides the process information required in the research-and-development
phase. The thematic spectrum of the SENSOR+TEST agrees to an
extraordinary extent with the topics and tasks that result from the
demand for greater energy efficiency. There is no optimization – and
today this can only mean reduction – of energy consumption without
sensor technology. . ... |

 Cognex
Corporation: Un fabricante de electrónica produce miles de números
de piezas diferentes y de alto valor, pertenecientes a productos
electrónicos entremezclados en la misma línea de montaje. El gran número
de productos diferentes que se construyen en la cadena, unido al hecho
de que muchos de los componentes que distinguen esos productos son muy
similares, dificulta la verificación por parte de los montadores de que
están integrando los productos de forma correcta. La dificultad para
identificar los componentes, combinada con el ritmo rápido de la cadena
de montaje, provocaba un amplio volumen de unidades que requerían de
reprocesamiento o que debían desecharse. El fabricante de electrónica
había sufrido previamente pérdidas anuales por valor de varios
centenares de miles de dólares cuando esos componentes defectuosos se
añadían a las unidades y/o se ejecutaban operaciones incorrectas. Un
problema adicional era su incapacidad para realizar seguimientos
sencillos del inventario de productos en proceso (WIP), lo cual era la
causa de que se requiriesen grandes sumas de dinero para las materias
primas en proceso. El fabricante pidió a Claire Lasers y otros varios
proveedores de sistemas de identificación por láser que le diesen ideas
acerca de cómo hacer frente a sus problemas. ... |

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 system to measure shaft
angles. ... |

World’s best vaccum seals tested but not

 Sensor
Technology Ltd: TorqSense, a non-contact digital torque monitoring
system that could guarantee an infinite lightness of touch has proven to
be the only way to test the seals of super high performance vacuum
systems. The ultimate fields of precision manufacture, such as
electronics, biophysics and thin film deposition where tolerances are
measured in atoms, are often conducted in hard vacuum to remove airborne
contaminants and avoid the performance reducing effects of tiny air
movements. However the vast majority of vacuum chamber designs require
seals for rotary drive shafts (called rotary feedthroughs) and
‘feedthroughs’ for the passage of materials, components, tools and
finished products. In high vacuum applications conventional seals are
unlikely to be able to achieve the performance specifications required,
so magnetic fluid seals are used. ... |

Barcode reader with integrated PROFINET |
| |
 The
BCL 548i from Leuze electronic is the world's first barcode
reader with integrated PROFINET. It is thus capable of being operated
directly in PROFINET networks. Furthermore, thanks to integrated switch
technology, the BCL 548i can also be used in a line network structure.
This minimizes cabling requirements and offers a high level of
transparency and flexibility. Simple start-up and operation. With the
integrated PROFINET interface, the device can be directly connected to a
control. As a result, the usual path via an additional gateway is
eliminated. Moreover, with the integrated PROFINET interface, the user
can easily operate the device via the control. The device is configured
by selecting modules directly in the control and then transferring them
from the control directly to the device. Should it be necessary to swap
out a device, the configuration is automatically taken over by the new
device. By means of the integrated switch function of the BCL 548i,
additional devices can be connected to one another in the PROFINET in a
line structure, as is typical for fieldbuses. ... |
