Description
Изобретение относитс к радиотехнике, может быть использовано в измерительных устройствах. Известны преобразоратели температуры в частоту импульсов 1,2. Один из известных преобразователей выполнен на основе транзисторного блокинг-ген ратора с врем задающим конденсатором и термочувствительным элементом. Недостаток этого преобразовател заключаетс в невысокой точности преобразовайи и невозможности получени выходной частотной релейной характеристики. Недостатком этого преобразовател вл етс невысока точность преобразовани . Цель изобретени - повышение точности преобразовани - достигаетс тем, что в предлагаемом преобразователе перва база однопереходного транзистора подключена ко второй обкладке дополнительного врем задающего конденсатора, а эмиттер подключен к точке соединени базы транзистора блокинг-генератора с основным врем задающим конденсатором и разр дным резистором .The invention relates to radio engineering, can be used in measuring devices. Known converters temperature to pulse frequency of 1.2. One of the known transducers is made on the basis of a transistor blocking gene rator with a time reference capacitor and a temperature-sensitive element. The disadvantage of this converter is the low accuracy of the conversion and the impossibility of obtaining an output frequency relay characteristic. The disadvantage of this converter is the low conversion accuracy. The purpose of the invention is to improve the accuracy of conversion - in the proposed converter, the first base of the unijunction transistor is connected to the second plate with an additional time of the driving capacitor, and the emitter is connected to the junction point of the blocking transistor generator with the main time driving capacitor and the discharge resistor.
