SOLID-4E Safety Light Curtains are now
also available as linked versions |
| |
 Leuze:
SOLID-4E Safety Light Curtains can be used both vertical as hand
protection, finger protection or access guarding, or horizontal for
danger zone guarding. Cascaded devices allow these applications to be
easily combined with one another. Both fixed connections in L-shape and
U-shape versions and variants with flexible cable connections can be
used here. The costs for mounting and cabling are considerably reduced
with the cascaded devices when multi-sided guardings have to be set up
or point of operation guardings have to be combined with danger zone
guardings as rear area protection. SOLID-4E Safety Light Curtains are
type 4 devices in accordance with IEC/EN 61496. They provide reliable
protection, and with their sturdy and fail-safe construction, they also
ensure the highest possible system availability. Protected by a
warp-resistant profile housing closed on four sides and with their
straightforward M12 connection system, SOLID-4E Safety Light Curtains
are a match for even the toughest industrial conditions ... |

Ispezione su linee produttive a volume
elevato: successo garantito con In-Sight |
| |
 Cognex:
InterControl produce termostati, fusibili termici, limitatori e un'ampia
gamma di prodotti complementari per il controllo e il monitoraggio della
temperatura nel settore degli elettrodomestici, del riscaldamento e
della ventilazione. Alla fine dell'anno scorso, per mantenere la
competitività e migliorare la qualità dei prodotti, lo stabilimento
tedesco con sede a Norimberga ha deciso di ricorrere a sistemi di
visione per migliorare l'accuratezza delle ispezioni qualitative. La
sfida: Un'unità di controllo della temperatura per l'industria degli
elettrodomestici prodotta a Norimberga doveva essere sottoposta a
un'ispezione qualitativa completa. L'unità di controllo era costituita
da una base in ceramica con un meccanismo bimetallico e varie opzioni di
connessione e fissaggio. La produzione avveniva in un processo
completamente automatizzato e, di conseguenza, era necessario rilevare
in modo affidabile tutti i difetti presenti in ogni unità. A tale scopo,
occorreva garantire che i componenti non presentassero fessure nella
base in ceramica. 50 milioni di unità di controllo della temperatura
all'anno ... |

Heat meter – Temperature sensor with MID
approval - Complete delivery program available |
| |
 With
the product line “temperature sensor technology”, JUMO is the
leading manufacturer and supplier of temperature sensors for heat meters
in Europe. The heat meter, like other measurement devices, is used for
the billing of goods or services (here heating costs) and thus is
subject to the legally binding metrology. In order to be able to be used
in commercial operations, the measurement device previously had to have
a model authorisation. In the required authorisation test, at first the
construction of the device was tested for compliance with the legal
requirements and for the measurement stability. After the measurement
device had been produced, the correct measurement was tested in a state
run testing authority which is independent from the manufacturer. The
measurement device did not receive the calibration stamp until then. ... |

Crevice-free compact pressure transmitter
for industrial and automotive applications |
| |
 With
the Series 22 S and 22 M, Keller AG für Druckmesstechnik,
Winterthur (Switzerland), has introduced a wide range of pressure
transmitters that are totally crevice-free after assembly. The brazing
technique that the company has developed has made the use of internal
O-ring seals obsolete for many applications. The parts that come into
contact with the media are made from stainless steel (AISI 316L) in the
Series 22 S transmitters. In the Series 22 M the steel piezoresistive
pressure measuring cell is brazed to the brass pressure connection using
a nickel diaphragm. Brazing in tunnel furnaces has considerable cost
advantages in comparison to the usual electron beam welding at measuring
ranges up to 250 bar. The Series 22 pressure transmitters are available
in finely graduated pressure ranges from 5 bar to 250 bar sealed gauge.

Laser sensors for reflecting surface |
| |
 Special
sensors for optical distance measurement of direct reflecting materials
are now available from Micro-Epsilon. Designated as the optoNCDT
1700DR, this new series expands the manufacturer’s already extensive
sensor family. Three sensors with the measuring ranges of 2mm, 10mm and
20mm are designed specifically for use with polished metals, glass or
chrome-plated products. The high measuring rate of 2.5kHz and the
maximum resolution of 0.1µm make precise measurement of the desired
targets possible. The reflected laser beam is guided into the receiving
array by tilting the sensor and is then directly converted into an
electrical signal by the integrated controller. The design is identical
to the successful optoNCDT 1700 standard series. As well as the
integrated controller, the series also incorporates a foil keypad
directly on the sensor, whereby adjustments without configuration
software are possible. The comprehensive ILD Tool 1700 software, which
also makes a measured value display possible, is included as standard
for more simplified operation of the sensor at a computer. A different
tilt angle is ... |

10 milioni di alternanze di carico a
±3.000 µm/m - gli estensimetri ottici ampliano le possibilità di
misurazione dell’estensione |
| |
 Per
l’analisi sperimentale delle tensioni e i test strutturali HBM
propone da subito estensimetri ottici (ER) per la misurazione
dell’estensione. Questi ER si basano sui cosiddetti reticoli di bragg in
fibra. I vantaggi degli ER ottici sono palesi. Per quanto riguarda la
vita a fatica raggiungono i 10 milioni di cicli di carico con una
deformazione alternata di ±3.000 µm/m. Ecco perché questi sensori sono
imbattibili in termini di durata ad esempio su materiali plastici
rinforzati in fibra in situazioni che prevedono elevate deformazioni
alternate. All’interno di una fibra di vetro possono essere applicati
più sensori, riducendo in questo modo il dispendio richiesto
dall’installazione. La modifica della lunghezza d’onda a seguito di una
deformazione meccanica in un range di deformazione di più di ±10.000
µm/m, è lineare. Gli estensimetri ottici sono particolarmente adatti a
misurazioni in ambienti con pericolo di esplosione e su componenti della
tecnica a corrente forte ed alta tensione. ... |
