EMX Industries Inc. Announces New Color
Management In-Line Product Expansion |
| |
 EMX
Industries Inc., a manufacturer of sensors for automation, announces
the ColorMax P version color sensor, the highest resolution and fastest
RGB sensor on the market. Data Logging: In addition, the ColorMax P
version application software allows for data communication and
statistical analysis based on the standard Office Excell software.
Non-Standard Features: EMX’s new sensor comes with standard features
that are not provided standard in the industry. Unlike many other
sensors, the ColorMax has full application software with control over
the target illumination and the ability to view color without reflection.
Most color sensors have only a red and green LED, which provide little
information. Also – unlike other color sensors – the ColorMax has no
controls on the sensor so unauthorized operator cannot change the
settings and cause errors. The output is automatically configured to PNP
or NPN upon power-up, aiding in setup. The light source intensity is
variable so it can be adapted to the background. Price and Availability:
The ColorMax sensor from EMX is available three weeks ARO. The price for
sensor is available upon request, with discounts available for quantity
orders. ... |

Capteur de surveillance isolé par rapport
à la masse avec sortie de courant |
| |
 Sur
les gros moteurs, la distance entre le site de montage du capteur et
l’électronique d’analyse peut atteindre 30 mètres. Lorsque le capteur et
l’électronique d’analyse sont tous deux reliés à la masse, des courants
transitoires de forte intensité peuvent circuler entre ces deux masses.
Dans ce cas, de puissants signaux parasites viennent se superposer au
signal de sortie analogique du capteur. Pour résoudre ce problème,
Kistler propose à présent un capteur de surveillance isolé par
rapport à la masse. L’intérieur du capteur type 6353A24 est isolé
électriquement par rapport au boîtier. Le boîtier de l’amplificateur de
charge n’est pas non plus en contact électrique avec le moteur. Cette
isolation par rapport à la masse évite que des circuits de retour à la
terre apparaissent entre le capteur et les appareils électroniques
montés en aval. Autre adaptation du capteur à l‘environnement
industriel, la sortie de courant, qui permet au signal de la pression du
cylindre d’être transmis sur de longues distances sans parasites. ... |

Capacitive Hygrothermo Transducers with
intelligent interchangeable probes |
| |
 Pluggable
and interchangeable measurement probes are the main characteristic of
this new device series from JUMO. The flexible concept allows in
practice a substantial simplification with assembly and operation. In
addition savings in the area of maintenance can be reached since in many
cases you can do without the time consuming and cost intensive
calibration on location. Through the new plug system and the calibration
data which is provided directly in the sensor, an exchange of the probe
is possible in just a few seconds. Downtimes can thus be limited to a
minimum. The high measurement accuracy of the hygrothermo transducers
remains unlimited through the intelligent interchangeable probes.
Nevertheless the calibration keys attached inside of the device allow
for a one or two point calibration of the device. For applications in
the fields of the pharmaceutical and the bio-technology industries, the
new measurement encoders are now specially available with separate
probes for moisture and temperature. ... |

 A
long-standing Swiss salt mine is impressed by the reliability and
sturdiness of KROHNE's OPTIFLUX 4300 electromagnetic flowmeters.
The role of salt should not be underestimated: Besides being used in
food preparation and its healing effects in spas, it is also an
essential raw material in the chemical industry. For over 170 years a
large Swiss salt mine in the Rhine valley has been supplying people,
spas and the chemical industry with this white gold. The level of

Aerospace & Defense division of PCB Piezotronics (PCB®) has
introduced a series of dynamic ICP® pressure sensors, Series 106, 116,
122, 123 and 124, designed expressly for measurement of combustion
instability and high intensity acoustics in rocket motors. The rugged,
hermetically sealed, piezoelectric pressure sensors are structured with
acceleration-compensated quartz sensing elements and detect rapid
pressure transients, pulsations, turbulence, noise, and spikes. They are
ideal for rocket motor testing to verify the amplitude and mode of
instabilities during motor firings. Other applications include
evaluation of liquid rocket injectors, hydraulic and pneumatic systems,
exhaust systems, compressors, turbines, pumps and pipelines, jet engines,
and weapons discharge. These devices monitor dynamic pressures while
subjected to high static background pressure. ICP® output features on-board

New generation pressure measurement |
| |
 Presens
AS has introduced the PRECISE, a rock solid pressure and temperature
transmitter designed for calibrators, digital gauges and other
applications where high accuracy, low drift and high resolution is
required. In comparison to conventional silicon pressure sensors that
use diaphragms with a piezoresistive resistor bridge to measure stress,
Presens pressure sensors measure pressure-induced compressive stress
with a piezoresistive Wheatstone bridge integrated on a tubular silicon
structure. The mechanical design of the sensing element makes it
possible to develop extremely robust and sensitive sensor solutions.
With a guaranteed total error band (all possible errors) of <±0.01%FS,
high pressure turndown ratio and an inherent tolerance to over-pressure
and pressure spikes, the PRECISE sensor offers a level of performance
unparallel to none. ... |

Connexions aseptiques interchangeables
CombiConnect |
| |
 Les
CombiConnect de Baumer Process Instrumentation (Groupe Baumer)
sont des systèmes de connexion aseptiques en acier inoxydable. Comme ils
sont interchangeables, ils offrent flexibilité et polyvalence, aussi
bien pour les instruments de mesure de pression que de température. Les
CombiConnect peuvent être utilisés avec plusieurs instruments de Baumer
Process Instrumentation : les transmetteurs de pression FlexBar et
ED701, et les systèmes de mesure de température CombiTemp. Ils visent
naturellement les applications mettant en œuvre des mesures de pression
et de température dans des environnements et des conditions de process
multiples. Non seulement très flexible, le système permet aussi de
réduire fortement les stocks d’instruments de rechange. Le système
CombiConnect Permet d’avoir un seul type de raccord sur l’instrument de
mesure sur lequel se montent un grand nombre de raccords process grâce
aux pièces d’adaptation du CombiConnect. Le montage se fait en moins de

Couplemètres à deux plages de mesure |
| |
 Kistler:
Les couplemètres de type 4503A… peuvent mesurer avec une grande
précision aussi bien des valeurs crêtes que des valeurs moyennes de
fonctionnement. Des rapports extrêmes entre couple maximum et minimum
sont observés, par exemple pendant le démarrage, les décélérations
abruptes ou le freinage de presses. Les vibrations de torsion, telles
que celles observées dans les moteurs à combustion, les pompes et les
compresseurs, entraînent également des charges maximale non
souhaitables. Pour éviter ces surcharges, les capteurs conventionnels
doivent donc être dimensionnés et réglés par rapport à la valeur crête.
Mais la résolution du signal est alors souvent insuffisante pour les
couples de fonctionnement effectifs, largement inférieurs, ce qui
entraîne des mesures imprécises. Ce couplemètre à deux plages de mesure
est donc la solution idéale pour ce type d’application. D’une part, il
est suffisamment robuste pour supporter et mesurer sans dommages les
valeurs de crête; d'autre part, la seconde plage de mesure offre une
résolution suffisante pour acquérir avec précision les couples de
fonctionnement même les plus faibles. ... |
