LVDT accelerometer

The LVDT accelerometer uses an LVDT (Linear Variable Differential Transformer) integrated into the structure of the accelerometer as a principle for detecting mass displacement. In these devices, the mass itself constitutes the ferromagnetic core of the LVDT sensor and flows (suspended on springs or other elastic elements) inside a channel, around which the coils destined to detect the position of the mass are wound.

A circuit detects the position of the core relative to the coils and generates an electrical signal proportional to the displacement with respect to the rest position.
