What is the working principle of LVDT construction?

The working principle of LVDT (Linear Variable Differential Transformer) construction is based on electromagnetic induction. An LVDT consists of a primary coil (excitation coil) and two secondary coils (sense coils) on a cylindrical core. When an alternating current (AC) voltage is applied to the primary coil, it creates a changing magnetic field in the core. This changing magnetic field induces voltages in the secondary coils, which are connected in a series opportunity configuration. As the core moves axially in the LVDT package, it changes the mutual inductance between the primary and secondary coils, resulting in a differential output voltage proportional to the movement of the core.

What is the working principle of LVDT sensor?

The working principle of an LVDT sensor involves detecting changes in the mutual inductance between the primary and secondary coils caused by the movement of the LVDT core. As the core moves linearly within the LVDT package, it changes the coupling between the primary and secondary coils, resulting in a change in the output voltage of the LVDT sensor. This voltage change is directly proportional to the displacement of the core, allowing the LVDT sensor to accurately measure linear displacements with high sensitivity and repeatability.

What is the working principle of linear variable displacement transducer?

The working principle of a linear variable displacement transducer (LVDT) is based on the linear relationship between the displacement of the LVDT core and the output voltage of the sensor. As the core moves axially in the LVDT package, it changes the mutual inductance between the primary and secondary coils, resulting in a differential output voltage proportional to the displacement of the core. This linear relationship allows the LVDT to accurately measure linear displacements over a wide range with high precision and resolution.

LVDT type accelerometers use LVDT technology to measure linear acceleration. The working principle involves the conversion of mechanical acceleration into linear displacement of the LVDT core. When subjected to acceleration, the movement of the LVDT core within the housing changes the mutual inductance between the primary and secondary coils, resulting in a differential output voltage proportional to the acceleration. By measuring the output voltage of the LVDT accelerometer, the linear acceleration can be determined accurately.
