FIELD: technical equipment measuring nonelectric values by electrical engineering methods, measurement of physical parameters. SUBSTANCE: in compliance with invention converter has current generator and resistance sensors connected according to fourwire circuit with two measurement networks and input and output network of current flow. Protective diodes are paced in parallel with each resistance sensor. Every i-th channel includes low-pass filter. In addition each measurement circuit is protected by two diodes, one of which being connected to output of current generator and the other one being connected to common point of converter. EFFECT: reduced operation error due to rise of noise immunity, improved protection against static electricity, simplified design of converter. 1 dwg
