Working principle
LVDT sensor 1000TD works based on the principle of differential transformer. It consists of a primary coil and two secondary coils. When the iron core moves in the coil, it causes the magnetic flux in the coil to change, thereby forming a voltage difference signal. After processing, this signal can accurately reflect the displacement of the iron core and achieve high-precision displacement measurement. Specifically, when the primary coil is connected to the excitation signal, the generated magnetic field will cause the two secondary coils to generate induced electromotive force. Since the secondary coils are connected in reverse series, the change in the position of the iron core will cause the output voltage of the secondary coil to change, forming a differential output signal.

Application
LVDT sensor 1000TD is suitable for various occasions requiring high-precision displacement measurement, especially for oil motor stroke, hydraulic cylinder piston positioning, valve position detection in steam turbines. Its excellent performance and reliability can meet the needs of various industrial applications and improve production efficiency and product quality.
Installation and use precautions
When installing the LVDT sensor 1000TD, make sure the sensor is installed on a flat surface, avoid being close to magnetic metal, generally at a distance of more than 20mm, and should not be close to strong magnetic fields or strong currents. During use, be careful to avoid bending forces, as this will affect its sensitivity. The connection of the wires is also a focus that requires daily maintenance and attention. If a broken wire is found at the welding point, it must be handled in time.
