955DQ BRIK Gen III Magnetostrictive LDT
In A Low Profile Package
The 955DQ BRIK is an accurate, auto-tuning, noncontact
linear displacement transducer in an
economical, low profile package with direct quadrature
output.
This new method of interfacing magnetrostrictive
transducers offers an interface as common as
analog but with the speed and accuracy of pulsed
type signaling. The Gemco 955DQ linear transducer
provides quadrature output directly from the transducer
to the controller. The output from the transducer can be
wired directly to any incremental encoder input card,
without the need for a special converter module or a
PLC interface card designed specifically for use with a
pulsed output magnetostrictive transducer.
The streamlined anodized aluminum extrusion houses
the sensing element and electronics. The BRIK with
quadrature output 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 deep. The magnet slide is designed to move
effortlessly along the transducer in a guide track or a
floating magnet assembly can be positioned above the
unit.
The 955DQ BRIK has a few truly unique features. First,
the LDT has auto-tuning capability. This is the abiliy to
sense a magnet other than the standard slide magnet
and adjust its signal strength accordingly. Another
feature is a diagnostic LED located at the connector end
of the probe that remains green when a good magnet
signal is present and power is normal. The LED turns
red when there is no magnet present or the magnet
assembly is out of the sensing area.
The 955DQ LDT can be ordered with 1-9999 cycles per
inch of output resolution in lengths of 5 to 180 inches.
The transducer features an input to re-zero the probe
“on-the-fly”. Another unique feature is the “burst” mode.
An input on the transducer triggers a data transfer of all
the incremental position data relative to the customers
set zero position. This can be used to achieve absolute
position updates when power is restored to the system,
eliminating the time consuming need to “re-home” the
machine.
