FIELD: measuring engineering.
SUBSTANCE: device has temperature sensor, constant power heater, accumulator, analogue-digital converter, multiplexer, source of stable current, digital control block, and indicator. The input of the analogue-digital converter is connected with the output of the multiplexer. The temperature sensor and the source of stable current are connected to the first input of the multiplexer. The input of the digital control block is connected with the output of the analogue-digital converter. The outputs of the digital control block are connected with the second and third inputs of the multiplexer, heater, and indicator.
EFFECT: enhanced accuracy and reduced power consumption.
