Miniature LVDT Position Sensors Provides Highly Accurate Position Feedback in Robotic Applications
The compact size and highly accurate output of Macro Sensors (www.macrosensors.com) CD 375 Series of miniature LVDTs make the linear position sensors ideal for providing displacement feedback in different robotic applications.
- (1888PressRelease) March 07, 2011 - 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" diameter design and lightweight low mass core make the small contactless position sensors ideal 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 0.025" (0.63mm) to 2.0" (50.0mm), these
AC operated linear position sensors offer a 50% larger core-to-bore radial clearance (0.012") than similar sized competitive units. Units feature excellent repeatability (error of
