a very sensitive transducer but the tip of the profilometer is conical and has a finite rounded shape, which interacts with the sample being scanned
Linear Variable Differential Transformer: a sensor that requires AC excitation of a primary coil to output AC from a secondary coil with amplitude that varies with position of a movable core
A differential output driver intended for use with a differential receiver; usually provided where long lines and high frequency are required.
Linear Variable Differential Transformer. Used in measuring devices that convert changes in physical position to an electrical output. Symbol for metre and milli- (thousandth). Symbol for mega (million).
