What is the function of LVDT?
The function of an LVDT, or linear variable differential transformer, is to accurately measure linear displacement or position changes. It converts mechanical movement into an electrical signal, providing precise feedback on the position of a moving object.
LVDTs are commonly used for position sensing in various industrial applications, including machine tools, automated manufacturing systems, aerospace, automotive, and robotics. They offer high precision, reliability and durability, making them suitable for demanding environments.
What is LVDT always used for?
The operating principle of an LVDT is based on electromagnetic induction. It consists of a primary coil energized by an alternating current (AC) power source and two secondary coils wound in opposite directions. A moving ferromagnetic core, usually attached to the object whose position is to be measured, passes through the center of the LVDT.
What is the principle of working of LVDT?
As the heart moves, it induces voltages in the secondary coils, which are connected in series opposition. The resulting voltage difference between the secondary coils varies linearly with core position, providing an accurate measurement of displacement.
LVDTs can be used as linear position sensors in various applications where precise measurement and control of position is required. They are often integrated into feedback systems for closed-loop control, allowing real-time adjustments based on position feedback. Additionally, LVDTs are used in instrumentation and test equipment for monitoring and recording linear displacement.
We hope this explanation of What is the function of LVDT? answered your questions.
