LVDT Sensitivity and Resolution


#1

Sensitivity and resolution of LVDT: are both same?

No.

Sensitivity is the response (o/p voltage) to change in input (displacement), it means in LVDT case we can define the sensitivity that how LVDT will respond to the small change in displacement or my LVDT is responding to the smallest change in input (displacement). Unit is V/mm.

Resolution is the smallest value (numerical value of the specification of the device) that can be observed, measured. Here it is smallest displacement not a change like sensitivity. It means smallest displacement which can be measure using LVDT is the resolution micro m or mm or cm etc.
