FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment and can be used in sensor systems to convert sensor signals (acceleration, pressure, radiation, etc.) into voltage. Measuring bridge with increased speed of response contains first (1), second (4), third (6) and fourth (8) measuring resistors, first (9) and second (10) parasitic capacitors associated with first (3) and second (7) outputs of the measurement diagonal. First (11) and second (12) inverting voltage amplifiers, first (13) and second (14) correcting capacitors are introduced into the circuit, while the input of first (11) inverting voltage amplifier is connected to second (7) terminal of the measurement diagonal, and first (13) correcting capacitor is connected between the output of first (11) inverting voltage amplifier and first (3) output of the measurement diagonal, the input of second (12) inverting voltage amplifier is connected to first (3) output of the measurement diagonal, and second correction capacitor (14) is connected between the output of second (12) inverting voltage amplifier and second (7) terminal of the measurement diagonal.
EFFECT: technical result - increase in the speed of response.
