An LVDT (Linear Variable Differential Transformer) is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31 mV/mm with a +/- 2 cm maximum core displacement. The spring constant is 240 N/m, and the core mass is 0.05 kg.
Find the relation between acceleration in m/s2 and output voltage.
Find the maximum acceleration that can be measured.
Find the natural frequency.
