A Fet Controlled Attenuator for Measurement of LVDT Output
Reshu Agarwal, Kirat Pal · 2007
A simple electronic circuit for measurement of displacement using linear variable differential transformer (LVDT) has been reported. The circuit uses FET as variable resistance to form an attenuator which works in accordance with excitation, and secondary output is rectified either positive or negative depending upon core positions. 1.
