After in-depth study of LVDT signal processing circuit
a basic solution for problems
such as: chip fever
temperature drift and signal accuracy
were presented.Meanwhile
an on-line monitoring method combining software and hardware was also proposed without addition of external components.The result of engine bench experiment proves the feasibility of this method.
