Linear Displacement Sensors

Result: 3







A linear displacement sensor is an electronic device designed to measure and detect the linear movement or position of an object along a straight path. These sensors play a critical role in various industrial, automotive, and automation applications, providing accurate and real-time information about the position of objects or machinery.

Types of Linear Displacement Sensors:

  • Potentiometric Sensors: Use resistive elements to measure displacement and provide an analog output.
  • Inductive Sensors: Utilize electromagnetic induction for non-contact displacement measurement.
  • Capacitive Sensors: Measure changes in capacitance to determine linear displacement.
  • Optical Sensors: Use light-based technology, such as encoders, for accurate position sensing.
  • Magnetostrictive Sensors: Employ the magnetostrictive effect to measure the position of a magnetic marker along a guided rod.
Applications: Manufacturing and Automation: Used in industrial machinery for precise control of linear movement in processes like assembly lines and robotics. Automotive: Employed in vehicle systems for monitoring the position of components such as throttle pedals, brake pedals, and suspension systems. Medical Devices: Applied in medical equipment to measure linear movement in devices like infusion pumps or robotic surgical systems. Aerospace: Used in aircraft and spacecraft for position sensing of control surfaces, landing gear, and other critical components.
