Ford Motor works
in Cologne used over 400 different sensors from various
manufacturers. Ford additionally maintained extensive inventories of
standard devices and non-official stocks in drawers and shelves.
Ford settled for 6 different Uprox+ sensors to replace all the
sensor variants used. |
New Factor 1 Inductive
Sensors
"Everything that can be invented, has
been invented". So said Charles Duell, Director of the U.S.
Patent Office in 1899! One might think the same about the inductive
proximity sensor. It has remained virtually the same since it's
invention over a century ago.
With a complete
departure from the traditional ferrite core, the new Uprox+ Sensors
offer many advantages over the old design. One of the primary
advantages is the achievement of Factor 1 sensing i.e. the ability
to sense all metals equally. Ferrite core sensors are rated by their
ability to sense a mild steel target but suffer huge loss of
sensitivity when detecting other metals.
A newly patented
multicoil system for the Uprox+ product line replaces the
conventional wound coil system used in the previous generation of
sensors. This results in extraordinary sensing distances (up to 250
percent higher than conventional ferrite core inductive sensors) in
a Factor 1 sensor. Due to the unique design, they give the
flexibility to incorporate this technology in several new housings
that solve a number of unique customer applications. All Uprox+
sensors have an environmental rating of IP 68 are weld-field immune,
provide an extended temperature range and offer highest levels of
EMC.
The ability to
lay the coils flat results in a totally new sensor which can replace
a ring sensor and is far simpler to install or replace.

Multibarriers
for Foundation Fieldbus & Profibus PA
With Foundation Fieldbus and
Profibus-PA fieldbus systems, many applications require Zone 1 installation. The
use of Multibarriers
allows the
use of a bus segment for the explosion hazardous area with the same segment
structures as in the non intrinsically-safe area , without the danger of
potential transfers. The supply of energy to the physical layer is implemented
in the non-explosion hazardous area – in the control room. The segment cable is
subject to the regulations governing enhanced safety (Exe). Junction boxes
(multibarriers) can now be connected to this bus cable, which subdivide the Exe
cable into 4 Exi trunk lines. As a result, it is possible to supply energy for
segments designed for longer distances. |

New Fieldbus Displays
These bus powered instruments,
which can display up to eight fieldbus process variables on a 86 x 45mm screen,
are available for use with Fieldbus Foundation or Profibus PA systems. One, two
or four fieldbus variables may be displayed at the same time, together with
units of measurement and tag information. The operator can select the displayed
screen via the front panel push-buttons, or these buttons may be disabled.
By writing to the transducer
block parameters, text and simple graphics can also be displayed. The
push-buttons can then be used to return operator acknowledgements: if large
industrial push-buttons are required for these operator inputs, external
push-buttons or switches may be wired to the instrument. The two intrinsically
safe models, which have ATEX, FM and IEC Ex certification, comply with the
Fieldbus Intrinsically Safe Concept FISCO.
