NOTE: Ametek has checked the accuracy of this manual
at the time it was approved for printing. This manual may
not provide all possible ways of installing and maintain-
ing the LDT. Any errors or additional possibilities to the
installation and maintenance of the LDT will be added in
subsequent editions. Comments for the improvement of
this manual are welcome.

Unpacking
Carefully remove the contents of the shipping carton and
check each item on the packing slip before destroying the
packing materials. Any damage must be reported to the
shipping company. If you do not receive all of the parts,
contact Ametek at 800-635-0289 (US and Canada) or
248-435-0700 (International).
Most probes are shipped
in a Tube. To remove the
metal end cap, use a large,
flat blade screw driver or a
metal rod and tap on the
inner edge of the cap until
it pivots. Grab the cap and
pull it out. Use caution as the edge of the metal cap may
be sharp.
If you have an RMA warranty claim, pack the probe in a
shipping tube or with stiff reinforcement to prevent the
probe from being bent in transit.
The 957SSI Brik™ is a magnetostrictive Linear Displace-
ment Transducer (LDT) for highly accurate continuous
machine positioning in a variety of industrial applications.
The 957SSI Brik™ provides a Serial Synchronous Inter-
face output signal that is proportional to the position of the
magnet assembly along the length of the probe.
This sensor is built to withstand the most severe environ-
mental conditions and is completely absolute. This means
that power loss will not cause the unit to lose position in-
formation or require re-zeroing. The non-contact design al-
lows this device to be used in highly repetitive applications
without mechanical wear.
Features
The 957SSI has auto-tuning capability. This is the ability to
sense a magnet other than the standard slide magnet and
adjust its signal strength accordingly.
There is an indicator LED that is located at the connector
end of the probe and provides visual status information re-
garding the operation of the probe. Green indicates proper
or normal operation. Red indicates the loss of the mag-
netic signal or a probe failure. When the probe is in the
normal mode of operation, the LED will remain illuminated
green continuously.
LED Colors*
Green Magnet is present and within the active range.
Red Fault, the LDT has lost its signal from the magnet or the
magnet has moved into the Null Zone or Dead Band.
*Refer to diagnostics on page 16 for a complete list of LED colors
and functions.
NOTE: The series number on your LDT is a record of all
the specific characteristics that make up your unit. This
includes what interface type it has, its output signal and
range, the type of connector the unit uses, and stroke
length. For a translation of the model number, see Sec-
tion 3.5 Part Numbering System.
