FIELD: instrumentation, development of devices based on measurement of resistance. SUBSTANCE: converter of resistance to D C voltage has source of reference voltage, operational amplifier, measured resistor, reference resistor connected to source of reference voltage and to inverting input of operational amplifier ( non-inverting input of operational amplifier is connected to common wire of circuit ), capacitor and low-frequency filter. One lead of capacitor is connected to inverting input of operational amplifier and its second lead is linked to output of operational amplifier. Input of low-frequency filter is connected to output of operational amplifier. One lead of measured resistor is connected to inverting input of operational amplifier and its second lead is linked to output of low- frequency filter. EFFECT: development of converter possessing protection against alternating current interference while operating with great resistance. 1 dwg
