Macro Sensors' CD 375 Series of
miniature LVDTs make the linear position sensors useful for providing
displacement feedback in different robotic applications.
Robots and robotic arms rely on
sensors to determine range of motion or force applied to an object. Attached to a robotic arm, the Macro Sensors
miniature LVDT linear position sensors detect position change when an actuator
moves the robotic arm, providing an analog voltage signal, proportional to the
amount of motion, to a controller that makes appropriate adjustments based on
programmable set points. With the data
provided by the sensor, the controller can determine when the robotic arm
should stop or slow down. For example,
on a pick and place machine, if the robotic arm exceeded its travel distance, it
could drive right through the board it intended to populate. Macro Sensors miniature linear position
sensors evaluate the robotic arm movement for optimum performance.
In addition to industrial robots, Macro Sensors CD 375 miniature LVDTs
are suitable as an integral part of devices such as hydraulic actuators, servo
valves, medical equipment and other small mechanisms. A compact 3/8 inch diameter design and
lightweight low mass core make the small contactless position sensors useful
for applications having high dynamic response requirements such as ATMs, copy
machines, plastic injection molding machines and automatic inspection
equipment.
Available in full-scale measurement ranges from A plus or minus 0.025
(A plus or minus 0.63)
to A plus or minus 2.0
inch (A plus or minus 50.0
mm), these ac operated linear position sensors offer a 50 percent larger core-to-bore
radial clearance (0.012 inch) than similar sized competitive units. Units feature
excellent repeatability (error of <0.01 percent of FSO), high resolution and
the highest sensitivity consistent with good linearity (maximum linearity error
of A plus or minus 0.25
percent FRO). Environmentally robust, the CD 375 Series operate in temperature
extremes of -65 to +220F (-55 to +105C). Stainless steel housings and epoxy
encapsulation protects units from environmentally hostile conditions. External
sealing of the miniature position sensors meets IEC standard IP-61. Interchangeable
with most manufacturer units, the CD 375 Series LVDTs operate with any
conventional differential input LVDT signal conditioners. Macro Sensors
manufactures a full line of LVDT signal conditioners that offer performance
from any CD 375 Series LVDTs.
