Description

Известны приборы подобного назначени  с термистором, подключенным в цепь измерительного моста.Instruments of similar purpose are known with a thermistor connected to a measuring bridge circuit.

Описываемый прибор по сравнению с известными аналогичного назначени  повышает чувствительность и увеличивает усиление сигналов измерительного моста. Дл  этого в нем при;менен фазочувствительный усилитель на кристаллическом триоде, в цепь коллектора которого включено пол ризованное реле, а термистор Зстановлен в закрытом металлическом патроне, залитом сплавом свинца и олова.The described device in comparison with the known similar purpose increases the sensitivity and increases the gain of the measuring bridge signals. To do this, the phase-sensitive amplifier on the crystal triode is changed in it; the collector circuit of which includes a polarized relay and the thermistor is mounted in a closed metal cartridge filled with an alloy of lead and tin.

На фиг. 1 изображен датчик; на фиг. 2-электрическа  схема прибора .FIG. 1 shows a sensor; in fig. 2-electrical circuit device.

Прибор включает датчик, в котором в качестве термочувствительного элемента применен термистор /, помещенный в металлическом патроне 2, залитом сплавом 3 свинца и олова. Патрон вставл етс  в молокопровод и закренл етс  головкой 4 и стопорным винтом 5. Выводы 6 термистора припаиваютс  к штепселю 7.The device includes a sensor in which a thermistor / is used as a temperature-sensitive element, placed in a metal cartridge 2, filled with lead and tin alloy 3. The cartridge is inserted into the milk line and closed with the head 4 and the locking screw 5. The leads 6 of the thermistor are soldered to the plug 7.

Термистор 1 подключен в цепь измерительного моста 8, плечами которого служат переменные сопротивлени  9 и 10 и посто нные сопротивлени  11 и 12. Сопротивление 9 служит дл  уравновешивани  моста в интервале контролируемых температур. При помоши этого сопротивлени  производитс  настройка прибора на заданную температуру сигнализации , а сопротивление 10-дл  корректировани  схемы в случае замены термистора.Thermistor 1 is connected to the measuring bridge 8, the arms of which are variable resistances 9 and 10 and constant resistances 11 and 12. Resistance 9 serves to balance the bridge in the range of monitored temperatures. With the aid of this resistance, the device is tuned to a predetermined alarm temperature, and the resistance is 10 to correct the circuit in case of replacing the thermistor.

В приборе применен фазочувствительный усилитель на кристаллическом триоде 13, в цепь коллектора которого включено пол ризованное реле 14. Контакты этого реле управл ют работой выходного реле 15. Лампочки 16 и 17 дл  сигнализации изменени  температуры относительно заданной.The device uses a phase-sensitive amplifier on the crystal triode 13, in the collector circuit of which a polarized relay 14 is connected. The contacts of this relay control the operation of the output relay 15. Light bulbs 16 and 17 for signaling the temperature change relative to the set one.
