采用分立元件设计了一种温度报警电路 ,可以在待测物的温度高于或低于所控温度范围时自动报警 ,以便及时调整热源 ,达到双限温度控制的目的
The use of discrete components designed a temperature alarm circuit can be measured when the temperature is above or below the controlled temperature range automatically alarm to timely adjust the heat source to achieve the purpose of dual temperature control
