A strain gage transducer or rather a large group of such transducers is balanced by a combination of at least one balancing resistor embedded in an insulating member and connected in a corner of a bridge circuit formed by the strain gages, and a number of adjustment resistors included in a flat, flexible printed circuit type cable having first conductor strips connected at one inner end to said balancing resistor in the embedding insulating member and electrically interconnected at the other output end. The adjustment resistors form part of the flat first conductor strips and are initially short-circuited by respective conductor strip sections which are interrupted for the adjustment.
