FIELD: measurement equipment.SUBSTANCE: invention relates to metrology. A measuring transducer includes the first transmission link, in which a measuring analogue input signal is processed by means of an analogue method and shaped in the form of a processed measuring signal. Besides, the measuring transducer includes the second transmission link, in which the measuring analogue input signal is processed and shaped in the form of a modulation signal, with that, the processed measuring signal and the modulation signal are shaped in a combination in the form of a measuring output signal. A temperature sensor is used as a meter, and the device also includes a modulator, a demodulator, a repeater, an optical coupler, an arithmetic device and a feedback device. With that, the modulation signal contributes to shaping of the measuring output signal by less than +/-10-5%.EFFECT: reducing response time; improved signal linearisation.12 cl, 1 dwg |
