Індуктивний негасенсор на операційному підсилювачі

Abstract

Inductive negasensor on operational amplifier includes voltage generator, measuring block, common bus, the first and the second resistors, inductance of primary measuring transformer, inductance, operational amplifier noninverting input of which is connected to the first output of measuring block and through inductance – to output of operational amplifier and first resistor, inverting input of operational amplifier is connected to the first resistor and through the second resistor – to common bus, second output of voltage generator, first output of inductance of primary measuring transformer and second output of measuring block, besides that it has ballast inductance first output of which is connected to voltage generator and the second – to the second output of inductance of primary measuring transformer, second output of measuring device, to inductance and noninverting input of operational amplifier.
