PCB Piezotronics New ICP™ Pressure
Response Microphone Offers ... |
| |
PCB Piezotronics (PCB®), a world leader in the design and
manufacture of vibration, acoustic, pressure, force, and torque sensors,
has introduced Model 377A13, a prepolarized, 1/2” pressure response type
microphone, operating from ICP® sensor power, which offers extended
frequency capability to 20k Hz (+ 2 dB). This microphone is designed for
applications requiring matching magnitude and phase at any position, to
properly measure changes caused by microphone presence in the sound
field, such as those required in confined spaces, like small cavities,
couplers, or impedance tubes. Previously, almost all ½” pressure
response microphones were limited to a maximum frequency of 10k Hz to
12k Hz, and thus could not be used in applications requiring full
audible range. ... |

Krohne’s OPTIMASS flowmeters help to
produce high quality bread products |
| |
 KROHNE’s
OPTIMASS 1000 Coriolis mass flowmeters are helping to ensure the
consistent quality of bagels produced at two manufacturing sites owned
by a leading UK baker. The flowmeters have been chosen as part of a
proportional weighing system built by Croston Engineering Ltd. The
instruments accurately measure the amount of palm and rape seed oil
added to the recipe and maintains the proportional ratio between flour
and all liquid ingredients. This ensures that the products meet
consistently high quality standards. Very small quantities of these oils
are added to the flour mixture during production. If too much or too
little is added it will adversely affect the texture of the product.
Traditionally, nutating disk type displacement flowmeters are used to
measure the flow of oil used in the production of bread products.
However, this method did not provide the level of accuracy the baking
company needed to achieve to maintain product quality. ... |

wenglor IO-Link - Breakthrough in the
Field of Communications |
| |
 One
of the most exciting topics at the 2007 Hanover Trade Fair was
undoubtedly the new IO-Link communication standard. 24 renowned
companies from the field of sensor and automation technology have joined
to form an IO-Link consortium. Amongst other factors, the stated
objective of the members was to reduce the various “languages” used by
their sensors to a single version, thus putting an end to the
communication chaos which prevails between sensors and the control
level. Together they developed IO-Link as a new uniform standard – and
wenglor made its contribution as well. wenglor goes IO-Link:
However, the idea of operating sensors and evaluating their signals at a
PC is nothing new for wenglor. In 1996 when the new era of
processor-controlled sensor technology was dawning with the advent
teachable sensors, wenglor had already integrated a serial interface
into all teachable sensors as standard equipment. wenglor sensors can be
configured, and can read out data to the controller, via this interface.
Thanks to implementation of the standardized IO-Link interface for
wenglor sensors, the customer is now even better able to incorporate
this time-tested interface function into his control concept. In
addition to this, standard inputs and master gateways are available as
well. wenglor’s IO-Link sensors can still be used as PNP/NPN sensors ... |

Mass measurement in BASF plastic
production |
| |
 BASF,
the world's largest chemical company, uses several KROHNE mass
flowmeters in the Luran factory at its headquarters in Ludwigshafen.
Plastic production has many complex requirements, which KROHNE is best
able to fulfill with its OPTIMASS 7000 straight-tube meter. The OPTIMASS
features problem-free commissioning and the ability to run idle even
when installed horizontally. When BASF undertook the conversion of an
old system in the Luran factory, KROHNE Coriolis meters were the first
choice. The OPTIMASS 7000 flowmeters are used when conveying solvents
and are the third generation of KROHNE Coriolis meters to be installed
by BASF in its systems. The OPTIMASS straight-tube design. KROHNE has
always relied on the straight-tube design in the Coriolis field, because
the advantages over mass flowmeters with bent or twin-tubes are obvious.
Curved or annular tubes and twin-tubes designs with flow dividers prove
to be unreliable in many applications using Coriolis meters. Various
media, such as viscous, non-Newtonian, fluids that are ... |

Regen drive turns laundry green |
| |
Sensor Technology Ltd: High performance torque measurement is
helping to improve the energy efficiency of domestic washing machines,
enabling consumers to make greener purchase decisions. The Eco Rating
stickers that provide potential buyers with a clear assessment of white
goods’ environmental performance now play a major role in retail sales.
Manufacturers want to achieve the best classification possible, so are
redesigning their machines to reduce power consumption. Technical
Solution of Stoke-on-Trent began looking at the issue and came up with
several initiatives that addressed different aspects of the situation.
One idea involved technology transfer from other fields of engineering.
Technical Director Andrew Stephen explains: “Washing machines energy is
delivered through their main drive motor and we reckoned that there may
be some savings using sophisticated motor control.” “Front loaders are –
of course – horizontal axis, so the load, i.e. the wet laundry, is being
lifted on one side of the axis and falling on the other side. We
wondered if this offered possibilities for regenerative energy recovery,
a technique ... |

 Melexis
introduces the lowest noise Photo Detector IC and the fastest Automatic
Power Control IC for both HD-DVD and Blu-Ray applications. Ieper,
Belgium – May 3rd, 2007 – Advanced disk storage technology is the key to
both HD-DVD and Blu-ray performance. Reading these next generation disks
demands a low system noise performance and fast response time. With
several companies producing the media it further challenges the system
design requirements. The difficulty in maintaining a very low, system
noise level has limited the capability of next generation systems.
Melexis, with the introduction of the MLX75013 Photo Detector IC and the
MLX75010 Automatic Power Control IC, now provides an enabling technology
for our OEM partners allowing them to overcome the noise and gain issues
limiting next generation systems. The MLX75013 Photo Detector IC
delivers an unprecedented noise rating of better than -90dBm (RBW=30Khz)

Laser fork sensors with specialized
optics |
| |
 Laser
with low beam spread thanks to STM precision optics. No aperture – high
precision even with mechanical deformation. STM now also offers
their patented precision optics with a laser as the optical element.
This produces a laser beam with an extremely low beam spread. Therefore,
a resolution of down to 0.06 mm applies over the entire fork width,
allowing objects to be detected precisely and reliably from emitter to
receiver. The fine, regular beam allows a high resolution without
additional apertures. In combination with the two-dimensional receiving
element, the resolution is maintained even in the event of mechanical
deformation. The GLSK Laser fork sensor will initially be offered with
fork widths of 30, 50, 80, and 120 mm. Versions with NPN and PNP outputs
are available. Light or dark switching can be set with a rotary switch.
Also, the switching frequency is 3 kHz, thus making the GLSK suitable
for extremely time-critical applications. The GLSK family features
especially small external dimensions. All products have a robust
aluminum housing, which guarantees mechanical stability for an extremely
precise optical acquisition system. ... |
