FIELD: instrumentation.SUBSTANCE: device contains the sensor, the first and second operational amplifiers (OA1, OA2), the first, second, third, fourth, fifth and sixth resistors, the first, second, third, fourth and fifth capacitors, the first and second rectifiers, the limiter, the shift bus. The inverting input of OA1 is connected to the first lead of the first resistor, and the output is connected to inputs of the first and second rectifiers. The output of the first rectifier is connected to non-inverting input of OA2 and through series connected fifth and sixth resistors with the output of the second rectifier and the second lead of the first capacitor. The first lead of the first capacitor is connected to the common bus. The inverting input of OA2 is connected through the fifth capacitor to the first lead of the third resistor and the first lead of the second resistor the second lead of which is connected to the common bus. The output of OA2 is connected to the first lead of the third resistor. The output of the limiter through the second capacitor is connected or to the inverting input of OA1 the non-inverting input of which is connected to the common bus, or to the sensor output. The sensor output through series connected third capacitor and the fourth resistor is connected to the second lead of the third resistor and the first lead of the first resistor. The second lead of the first resistor is connected through the fourth capacitor to the sensor output and directly to the limiter input and the output of the first rectifier which through series connected fifth and sixth resistors is connected to the output of the second rectifier and the second lead of the first capacitor. Note that the point of integration of the fifth and sixth resistors is connected to the shift bus.EFFECT: simplification of the device, reduction of dimensions and improvement of reliability.5 dwg |
