FIELD: electricity.
SUBSTANCE: fast-response sensor of physical characteristics with the voltage output consists of a sensor (1) with the inner reservoir (2) and the inner resistance (3) coupled to alternating current between an input (4) of an inverting buffer voltage amplifier (5) which output (6) is an output of the device and the common power supply bus (7). The device output (6) is connected to the input (4) of the inverting buffer voltage amplifier (5) through in-series balancing capacitor (8) and an auxiliary inverting current amplifier (9).
EFFECT: improving fast response of the sensor due to minimisation of impact of the inner capacity 2 of the sensor 1 on the transient process related to discontinuous change of the measured value.
