TEMPERATURE METER Russian patent published in 2001 - IPC

Abstract RU 2165600 C2

FIELD: electronics, temperature measuring devices. SUBSTANCE: temperature meter includes source of reference voltage, bipolar transistor, resistor, D C amplifier and indicator. Base of bipolar transistor is connected to source of reference voltage, its emitter is connected to resistor and inverting input of D C amplifier. Source of reference voltage is also coupled to noninverting input of D C amplifier whose output is coupled to indicator. Second lead-out of resistor is connected to common wire of circuit. EFFECT: expanded functional capabilities of temperature meter that can be used as high-precision temperature indicator. 1 dwg
