Sensors for Water Treatment Applications |
| |
 Water
treatment applications place high demands on pressure and level
measuring instruments. For these applications, Baumer offers
robust sensors which are suitable for high vibrations as well as for the
use with aggressive media. For example, sensors made of
seawater-resistant Hastelloy C and with a ceramic sensing element are
available for desalination plants. Flush mount versions are offered for
sewage applications. The devices can be easily configured on PC via the
FlexProgrammer 9701. Pressure and level measuring devices for water
treatment applications have to be extremely robust. First of all, this
concerns the materials used in instruments that are in contact with
aggressive or corrosive media in applications such as desalination
plants or sewage sludge processing. In addition, the devices have to be
highly resistant against vibrations which are generated continuously for
example in applications with volumetric pumps. Further challenges are
the formation of foam, suspended solids, and condensation in tanks. For
these challenges, Baumer offers an extensive portfolio of pressure and
level sensors ... |

Differential pressure measurement with
even better zero-point accuracy |
| |
 The
first dynamic digital differential pressure sensor from Sensirion,
the SDP600 series, was awaited with great anticipation. This was hardly
surprising, since the advance specifications of the small, fully
calibrated sensor included outstanding long-term stability and a short
response time along with high accuracy and sensitivity, even with very
small differential pressures (less than 10 Pa). Accumulated practical
experience with the sensor and test results now show that the
performance exceeds the high standard of the advance specifications. In
particular, the range of zero-point variation is three times less than
expected. The maximum deviation from the zero point was originally
specified as 0.5 Pa, but now it has been restated as 0.2 Pa. The SPD600
series also solidly fulfils its expectations with regard to reliability
and other specifications. With this, the new sensor achieves ... |

Marcatura laser e lettori ID industriali
a gestione di immagini permettono di risparmiare centinaia di migliaia
di dollari |

 Cognex
Corporation: Una ditta di componenti elettronici produce migliaia di
preziosi prodotti con codici diversi sulla stessa linea di assemblaggio.
Il gran numero di prodotti diversi realizzati sulla linea, unito
all'elevata somiglianza di numerosi componenti, rendono difficile la
verifica del corretto assemblaggio delle parti. Le difficoltà legate
all'identificazione dei componenti, unite ai rapidi ritmi della linea,
risultavano in grandi quantità di prodotti da rielaborare o scartare. La
ditta in questione aveva già sofferto perdite annue di diverse migliaia
di dollari a causa di componenti difettosi e/o di operazioni errate. Vi
era inoltre il problema di non poter rintracciare facilmente le scorte
di materiale in lavorazione, con il conseguente investimento di somme
ingenti di denaro in materie prime. La ditta ha chiesto a Claire Lasers
e a parecchi altri fornitori di sistemi di identificazione laser di
proporre possibili soluzioni. L'applicazione era particolarmente
complessa in quanto lo spazio a disposizione per l'apposizione del
codice identificativo su numerosi componenti era limitato e in quanto
l'elevato valore delle unità imponeva la massima precisione. Senza
contare che le unità non venivano posizionate e fissate sulla linea di
assemblaggio con il livello di accuratezza generalmente richiesto per
l'ispezione laser e la lettura ID a gestione di immagini ... |

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. . ... |

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. ... |

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,

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. ... |
