AUTOMATION & PROCESS
TECHNOLOGIES
955
With the demand for automation greater than ever, the
need to replace limit and zone sensors on pneumatic
cylinders with continuous feedback has become obvious.
Speeding up and improving your process is what you
need in order to stay competitive. Knowing your exact
position at any given moment is essential to that end.
Replace your existing limit sensors with the GEMCO
955C BRIK GEN III for continuous position feedback
with your choice of Analog, Digital, or Quadrature
outputs. The 955C BRIK GEN III senses the magnet
located in your existing pneumatic cylinder and uses it to
relay absolute positioning information to the machine’s
controller. The 955C BRIK GEN III can be retro-fitted to
cylinders in the field using standard mounting brackets
or your own customized solution. The 955C solution has
no moving parts to wear out. Magnetostrictive technol-
ogy is used to “see” through the aluminum extrusion and
detect the position of the magnet mounted inside the
cylinder.
Three versions of the 955C BRIK GEN III are available.
The 955CA offers analog output in either voltage or
current with your choice of 0 to 10 VDC, 10 to 0 VDC, 4
to 20mA, or 20 to 4mA. The unit can easily be reconfig-
ured in the field from a 0-10 VDC to a 10-0 VDC or 4-20
mA to a 20-4 mA output.
The 955CD is designed for digital output with choice of
Control Pulse, Start/Stop Pulse, or Variable Pulse output.
The Quadrature output from the 955CDQ allows wiring
directly to any incremental encoder input card, with-
out the need for a special converter module or a PLC
interface card. The 955CDQ 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 trans-
fer of all the incremental position data relative to the 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.
The 955C BRIK GEN III has truly unique features. The first
one being the LDT’s auto-tuning capability: the ability to
sense a magnet within the pneumatic cylinder and adjust its
signal strength accordingly.
Another feature is that the analog output is programmable
over the entire active stroke length. The active stroke area
of the LDT lies between the Null Zone and the Dead Band.
There is also a diagnostic LED located at the connector to
minimize setup time and troubleshooting. The LED is green
in normal operation. Red will indicate no magnet present
or that the magnet has moved out of sensing range. Yellow
is an indication the magnet is out of the programmed active
range or if no interrogation signal is detected.
The enclosure comes standard as IP67; however, up-
grading to IP68 is available as an option so the LDT can
be used in wet environments.
Note: The Pneumatic cylinder must have a magnet in order
to work. Each cylinder manufacturer uses different types
of magnets. In most cases the cylinder supplier installs the
magnet so that the South Pole is facing out. To date, we
have successfully worked with most brands of pneumatic
cylinders. Consult AMETEK APT for a list of compatible
cylinder manufacturers. Call 800.635.0289 to speak with
