AUTOMATION & PROCESS
TECHNOLOGIES
955
The transducer can be mounted vertically or horizon-
tally using our mounting feet which slide on the lower
part of the extrusion and clamp down when tightened.
This packaging provides a compact and easy method of
mounting for machine builders.
The 955 eBrik™ is designed for applications where eco-
nomical continuous feedback is necessary. The sensor
can be a cost effective replacement to linear potentiom-
eters, limit and proximity sensors.
Applications include presses, blow molding, injection
molding, extruding, roll positioning, tire press, and many
more.
955 eBRIK TM High Resolution
Magnetostrictive LDT In A Low
Profile Package
The 955 eBrik™ is an accurate, programmable zero and
span, auto-tuning, non-contact linear position sensor in
an economical, low-profile package. The sensor utilizes
our field-proven Magnetostrictive technology to provide
absolute position, repeatable to .001% of the sensing
distance. The 955 eBrik™ is a cost effective linear sens-
ing solution.
The streamlined anodized aluminum extrusion houses
the sensing element and electronics. The magnet moves
over the sensing element that determines the position
and converts it to a readable output. The 955 eBrik™ is
a self-contained unit and does not have a “can” or head
assembly. All of the electronics are incorporated in the
transducer, which is less than one inch tall.
Units can be ordered in span lengths up to 72 inches
long in 1 inch increments. The slide magnet is designed
to move effortlessly along the transducer in guide tracks,
or a floating magnet assembly can be positioned above
the unit. A variety of hardware is available for attaching
the magnet slide to the moving portion of the process.
The transducer can be ordered with 0 to10 VDC or 4 to
20 mA output.
All units are provided with our standard 5 pin 12mm Euro
Micro connector, mounting feet and magnet assembly.
Mating cables are sold in various lengths and must be
ordered separately.
The 955 eBrik™ has a few truly unique features. One
feature is the LDT’s auto-tuning capability, the ability to
sense the distance between the magnet and the sens-
ing surface and adjust its signal strength accordingly. As
a bonus feature, the 955 eBrik™ offers Programmabil-
ity, the ability to rescale the Zero and Span positions
or invert the positions in the field. This is an optional
feature and must be called out at time of order under the
“Options” field. All units come fully programmed from the
factory, are 100% absolute, and do not require repro-
gramming unless desired. There is a unique diagnostic
that is built into the analog output on every unit. If there
is a loss of magnet, or if the magnet assembly moves
beyond the programmed range, the analog output will
transmit a fault voltage or current, warning the host con-
troller that it is out of range.
