FIELD: physics.
SUBSTANCE: resistance strain gauge signal converter contains operational amplifier, and power supply connected to one terminal and global bus of the converter, output of the operational amplifier is connected to the second terminal, complemented input is connected to the third terminal. Additionally the converter includes voltage source and commutator switch contact of which is connected to uncomplemented input of the operational amplifier, other two contacts of the commutator are connected respectively to one terminal of voltage source and global bus of the converter connected to other terminal of voltage source.
EFFECT: improved performance of the converter.
