Abstract

A locating appliance configured to sense an article includes a push-pull measurement bridge and a comparator. The push-pull measurement bridge is configured to actuate a first electromagnetic device and a second electromagnetic device, in each case in a variable ratio. The first electromagnetic device takes the actuation as a basis for producing an electromagnetic alternating field in a region of the article. The comparator is configured to sense the article if the variable ratio differs from a predetermined ratio by more than a predetermined amount.
