Comprehensive Trade Fair Acitivies and
Programme |
| |
The SENSOR+TEST 2007 opens its gates on 22 May in Nürnberg for
visitors and, as at previous events, again offers an attractive
programme complementing the traditional trade fair activities. A special
highlight is the Action Area (Hall 8), where visitors can experience
sensor and measuring technology live. The parallel conferences as well
as the PCIM, which is being held at the same time, allow visitors during
the 3-day fair to obtain comprehensive information and to exchange
experiences with other professionals. “The SENSOR+TEST will again
provide comprehensive information for our visitors”, says Holger Bödeker,
Managing Director of AMA Service GmbH, the organisers. “Besides the
traditional conversations with customers at the stand, the diverse
platforms offer many opportunities for technical discussions.” ... |

KROHNE concludes framework contract with
Uhde |
| |
KROHNE Messtechnik has concluded a framework contract at this
year's Hannover trade fair/Interkama with Uhde regarding the supply of
flowmeters. The agreement encompasses electro-magnetic, Coriolis and
variable area flowmeters. In addition, Uhde can also obtain ultrasonic
and vortex flowmeters from KROHNE with very favorable terms. KROHNE
views the conclusion of this framework contract as confirmation of its
competence in the ultrasonic field and as a mark of success of it’s
latest Vortex flowmeter. For Uhde, the contract enables them to handle
projects with greater efficiency, which will benefit the end customer.
Stephan Neuburger, manager of the KROHNE group, explains: "We are very
pleased that the many years of faithful cooperation between KROHNE and
Uhde has now culminated in a framework contract, which will bring
comprehensive advantages to both sides.“ More information: ... |

SENSOR Innovation Award 2007 - The AMA
Association for Sensor Technology Recognizes Two Projects |
| |
|
For the seventh time, the AMA Association for Sensor Technology has
sponsored the 10,000 € SENSOR Innovation Award, presented at the
SENSOR+TEST 2007. After a slight decline in the number of submissions
from abroad last year due to the changeover to an annual cycle of the
SENSOR+TEST, the figures regained their customary high level for the
SENSOR Innovation Award 2007. Thirty percent of the submissions were
from abroad. The number of applications has also increased. The jury,
chaired by Prof. Dr. Andreas Schütze (University of Saarbrücken), had
already selected four projects in February for nomination, two of them
from abroad. Three of the four projects deal with new developments in
gas analysis – a distribution of research fields never before
encountered in the history of the SENSOR Innovation Award. ... |

PERKINELMER debuts new addition to
DIGIPYRO™ family for motion detection applications |
| |
New DigiPyro™ is World’s First Digital Quad-Element Pyrodetector,
Providing Improved EMI Immunity and Built-In Temperature Reference
Channel. Nuremberg, Germany – SENSOR + TEST 2007 – Booth # 7 / 265 –
PerkinElmer Optoelectronics, a global technology leader in digital
imaging, specialty lighting and optical detection technologies, today
announced the introduction of the newest product in the DigiPyro family
of digital pyroelectric infrared sensors, the DigiPyro™ Triple Channel,
PYQ 2898. DigiPyro products are utilized in a range of home and
industrial motion detection applications including intrusion alarm,
motion-activated light switches, and door openers. The DigiPyro Triple
Channel, PYQ 2898 is the world’s first pyrodetector with a quad- element
design with three channels; two pairs of elements representing two
channels and an additional temperature reference channel, thereby
allowing for more information to be provided to the hosting
microprocessor. The triple channel, quad-element detector provides OEMs
with performance advantages over traditional analog pyrodetectors, such
as reduced system costs and space requirements associated with analog
circuitry. Until PerkinElmer’s introduction of the DigiPyro family,
traditional detection instrumentation relied upon analog signal
processing for motion detection applications. To process an analog
signal, these detectors require additional system components such as
amplifiers, resistors, capacitors for EMI filtering, and A/D converters
- all components that add to system costs without improving performance.
PerkinElmer tests have shown that by utilizing the new DigiPyro Triple
Channel, PYQ 2898, the power supply rejection ratio (PSRR) is improved
by approximately 30 dB or a 32-fold improvement in EMI immunity over
analog pyrodetectors ... |

Force limited vibration test on ESA
Satellites |

Kistler force links on the interface base plate. Kistler has
played its part in European space technology for quite some time – the
most recent at ESTEC in Noordwijk, Netherlands. At the European Space
and Research Test Centre (ESTEC) in Noordwijk, satellites and components
are tested to verify that they will survive the extreme loads that they
will see during launch. Several vibration facilities are available at
ESTEC to cover the large range of specimen size: The smallest system is
a 80 kN electrodynamic shaker (LDS 964) that is used for specimen until
a few hundred kilos. The second system is a multishaker system combining
the force of two 160 kN shakers to test specimen up to 5 tons. Finally,
a large 6-DOF hydraulic platform can be used for the largest specimens
(up to 25 tons). During the vibration test, the acceleration at the
specimen mounting interface is usually controlled. To prevent the
specimen from destruction when resonance frequencies are reached it is
required to control the forces and moments at which the specimen is
submitted. In order to measure these forces, ... |

Air Velocity Transmitter Series EE75
from E+E Elektronik |
| |
 Measurement of Air and Gas Speed, Temperature and Volume in Industrial
Applications. The air velocity transmitter EE75 from E+E
Elektronik has been designed for accurate measurement of air speed
and gas flow between 0 and 40m/s (0…8000ft/min). The high-quality hot
film sensor element is based on state of the art thin film technology
and guarantees highest sensitivity even at very low mass flows.
The innovative construction of the sensing head reduces to a minimum the
impact of the mounting angle on the measurement results. The EE75 can
detect and measure even smallest flow changes due to temperature
variation, whereby resulting fluctuations of the output signal can be
suppressed by the user by software settings. The temperature
compensation integrated in EE75 reduces to minimum the influence of
temperature on the gas velocity measurement. The robust metal housing
allows the use of EE75 at process temperatures between ... |

Air quality signal creates good working
climate |
| |
 Not only the stressful job makes people tired at their workplace but
also the “stuffy” air, produced from the exhaled carbon dioxide (CO2).
Although it is only toxic at high concentrations, it can induce such
disorders as headaches and fatigue at considerably lower concentrations.
This problem can easily be resolved with systematic airing. But when and
for how long?
As humans can neither smell nor taste CO2, the air quality signal from
J. Dittrich Elektronic is of help here. The device fast and
precisely detects with the help of a patented infrared system the CO2
content in the ambient air and signals, how stuffy the air is. Green
light indicates good air quality, yellow light means air of medium
quality and red light signals bad air quality. The window should be
opened by now at the latest. The air quality signal is ready for
operation, maintenance-free, long-term stable and cost-effective. ... |
