Abstract
A force sensor includes a transducer with a measuring element operatively connected to a measuring object for generating measuring signals of a force acting on the measuring object, and two in parallel transmission channels transmit mutually corresponding signals of the measuring signals independently from one another and connected in parallel to the same transducer. A test signal is evaluated in a transmission channel in which the test signal has been injected and in another transmission channel in which the test signal has not been injected. In another testing method, the transmitted signals are compared.
