WebbThe net output voltage is V 0 =V 1 -V 2 is positive. Case 3:- LVDT Core is moved Right of null position. When the core of LVDT core is moved to right, then more flux links with coil S 2 than S 1. Hence voltage induced in S 2 is greater than S 1. The net output voltage is V 0 =V 1 -V 2 is negative. Output characteristics of LVDT Webboutput is then divided by the B output to produce a final output which is ratiometric and independent of the excitation voltage amplitude. Note that the sum of the LVDT …
