Macro Sensors to Include Miniature LVDT Position Sensors in Robotic Applications

Macro Sensors have developed miniature LVDTs (Linear Variable Differential Transformers), which are electromechanical transducers used in position sensors for robotic applications.

Their portability and accurate output make them perfect for providing displacement feedback in the various robotic applications. Robotic arms and robots depend heavily on sensors for determining the range of motion or the force needed to be applied on an object connected to the robotic arm. The LVDT linear position sensors observe the position changes that occur when an actuator moves the robotic arm and sends an analog voltage signal, which is equal to the amount of motion to a controller, which makes suitable adjustments, which are founded on programmable set points. The sensor provides the data and the controller finds out when the arm should either slow down or stop. These sensors thus analyze the robotic arm movements for maximum performance.

The CD 375 range of miniature LVDTs are suitable not only for industrial robots but are also apt for devices such as servo valves, hydraulic actuators, and medical equipments along with other tiny mechanisms. Its lightweight low mass core and size of 3/8 inches makes these contactless position sensors appropriate for applications that have high dynamic response requirements in equipment such as automatic inspection devices, plastic injection molding machines, copy machines and ATMs.
