FIELD: electricity.
SUBSTANCE: resistance increment converter contains a bridge consisting of resistors R1, R2, R3, R4 and resistance R5, two power supplies, two operational amplifiers, the inverting input of the first operational amplifier is "grounded", the non-inverting input is connected to the resistance connection point R3, R4, and its output to resistance R5, the other end of resistance R5 together with the connection point of resistors R1, R2 are connected to the inverting input of the second operational amplifier, the non-inverting input of which is "grounded" along with "grounding" of both power supplies.
EFFECT: increasing the accuracy of the conversion of the increment of resistance to voltage.
