FIELD: radio electronics; remote wireless temperature measurements. ^ SUBSTANCE: converter has power supply that functions as sensing element, as well as high- and low-frequency generators. Power supply has thermoelectric battery connected to voltage changer. Regulated-voltage output of power supply is connected to high-frequency generator. Power supply output placed at voltage proportional to temperature being measured is connected to low-voltage generator. Low-voltage generator functions as modulator for high-frequency one connected to antenna. ^ EFFECT: ability of dispensing with cable line between point of measurement and data processing unit and of using sensing element as power supply. ^ 1 cl, 1 dwg |
