摘要

Measuring device comprises an electrically conducting measuring surface (6) and an electrically conducting contact on the rear side; and an electrical connection consisting of electrical conductors and a shunt (10) connected in series. The electrical connection joins the measuring surface and the contact on a short path. Two electrical conductors collect the measuring signal from the shunt and feed it to an amplifier and/or evaluation unit. The measuring surface is electrically insulated from the contact by an isolator (11). Preferably the contact is in the form of a contact surface (12). The measuring surface, isolator and contact surface are arranged in a planar parallel manner.
