Abstract

A measuring system according to an exemplary embodiment acquires a measurement value indicating electrostatic capacitance between a measuring device and a transport fork for transporting the measuring device. The transport fork includes a target electrode. The measuring device includes a first sensor provided on a base board. The first sensor includes a central electrode and peripheral electrodes. The central electrode acquires electrostatic capacitance for reflecting a distance with the target electrode. The peripheral electrodes are disposed around the central electrode to acquire electrostatic capacitance for reflecting an amount of deviation in a horizontal direction with respect to the target electrode of the transport fork.
