Clinching and Riveting Free of Faults |
| |
 |
In the automotive industry today, very often doors, hood lids and
tailgate lids are being manufactured using clinching instead of spot
welding. This clinching process today is mainly used for aluminium
parts, but it is also ideal for joining sheet metal parts and profiles
of varying thickness and materials. In contrast to riveting, localized
cold forming without ancillary joining parts produces non-detachable
bonds. |
|
|
The force necessary for plastic deformation can be used for process
monitoring. It detects: dimensional deviations or an incorrect number of
sheet metal parts, - state of wear of the clinching tool, - process
faults such as punch or swage breakage, - incorrect setting of the press
height, - insufficient bottom thickness. Permanent monitoring of the
clinching force cycle using piezoelectric measuring technology from
Kistler not only makes the process cycle transparent, but also
monitors the long term stability of a clinching machine. Clinching tongs
can thus be periodically checked with the calibration transmitter Type
9831C322. Their parameters are documented and, if necessary, readjusted.
The calibration transmitter can also calibrate sensors for indirect or
direct force measurement in the machine. Pop or blind riveting can also
be monitored and documented by integrating piezoelectric force sensor
technology ... |

A Different Way to Measure Concentrations |
| |
 |
Measuring concentrations is a routine task in the process industry.
There are currently various processes available for measuring the
concentration of two-component mixtures of immiscible liquids. From the
most common (taking a sample and analyzing it in the laboratory), to
measurement of density, refraction index, optical absorption, or online
analysis. Thanks to research carried out by KROHNE, there is now
another measure method using the latest TDR level meters, which relies
on the dielectric constant. |
|
|
Finding the dielectric constant of two-component mixtures makes it
possible to calculate the proportion of each component. As the cost of a
KROHNE TDR level meter is considerably lower than that of the other
processes (as much as 10 times lower in the case of online analysis
devices), it is an economical and efficient alternative. OPTIFLEX type
TDR level meters are maintenance free, have no moving parts and can also
work with suspensions, such as Xylene and water. In this case the
OPTIFLEX can also be used for recognizing separate layers, for example
for separations in the batch process. ... |

Sonardyne agreement signed |
| |
Xsens has signed an OEM supply and distribution agreement with UK
based Sonardyne, to supply the inertial technology for RADIAN. RADIAN is
a miniature Attitude and Heading Reference System, optimized for use
sub-sea or at sea level. Supplied within an underwater pressure housing
(500m depth rating) and accepting a wide range of input voltages, Radian
can be mounted anywhere on vessels, ROVs, AUVs and structures. Radian is
compatible with Sonardyne's Scout USBL subsea positioning system.
Sonardyne prefers Xsens’ inertial technology because of the excellent
price performance ratio and the high quality of Xsens’ products. Simon
Partridge, Engineering Director at Sonardyne: “The MTi has proven to be
a reliable measurement instrument”. Xsens cooperates with Sonardyne
because of its world leading position in underwater equipment and its
international sales and support network. Established in 1971, Sonardyne
is an international group of companies manufacturing subsea
instrumentation. It is specialized in the use of sonar for underwater
navigation, positioning, data communication and control. ... |

Kistler wins the 2006 SVC Business Prize
for the Zürich Economic Area |
| |
 |
Kistler has been announced as the winner of the first ever
Business Prize for the Zürich Economic Area, awarded by the Swiss
Venture Club (SVC). The 12 strong independent expert jury honoured "Kistler’s
technological and innovative leadership and the excellent customer
benefits of its products". Kistler was up against 70 companies from the
region who also entered the competition. |
|
|
After an initial selection process, a shortlist of 12 candidates was
drawn up. In a second selection stage, the list was cut to six finalists
who were all visited by the jury members and subjected to an in depth
examination. In his short speech, Rolf Sonderegger emphasized that the
key to the success of the Kistler Group was its innovation and the
commitment of its staff. The Swiss Venture Club, founded in autumn 2003,
is a Swiss association with the aim of serving as a networking platform
for innovative and competition focussed SMEs. With its Business Prize,
SVC is rewarding innovative companies having achieved significant and
sustained economic success through excellent performance. ... |

ROTOSAFE Rotary Level Indicator |
| |
 |
4B introduces a new and improved Rotary Level Indicator. The ATEX
approved RotoSafe incorporates two detection circuits. One circuit
indicates when material has impeded the paddle, and the other circuit
provides indication when the paddle stops turning, therefore making it a
failsafe solution for high level or plug condition monitoring in bins,
silos elevators or conveyors. |
|
|
Bonus features include user adjustable sensitivity, LED indication and a
corrosion resistant housing. Specifications: Supply: 120/240 VAC /24 VDC
- Approvals: CE approved for Europe. ATEX versions available - Class 2
Division 1 groups e, f, g for US & Canada - Protection: IP65 – NEMA 4 -
Enclosure: Flame-retardant glass fiber reinforced nylon - Output:
Changeover Relay Contacts - Weight: 2.25 lb. ... |
