when does the phase shift in lvdt output signal occurs
Linear variable differential transformer When the core is displaced toward the top, the voltage in the top secondary coil increases as the voltage in the bottom decreases. The resulting output voltage increases from zero. This voltage is in phase with the primary voltage. When the core moves in the other direction, the output voltage also increases from zero, but its phase is opposite to that of the primary. The phase of the output voltage determines the direction of the displacement (up or down) and amplitude indicates the amount of displacement. A synchronous detector can determine a signed output voltage that relates to the displacement.
Central Time Zone Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most (but not all) of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.
