Abstract
The invention provides a natural gas tobacco flue-curing house temperature alarming device circuit comprising a switch, a power supply, a temperature detection control circuit, a temperature indication circuit, and a sound alarming circuit. The anode of the power supply is connected with the first end of the switch. The temperature detection control circuit comprises a temperature sensing control integrated circuit, a first potentiometer, and a second potentiometer. The high trigger end of the temperature sensing control integrated circuit is connected with the first end of the first potentiometer, and the lower trigger end of the temperature sensing control integrated circuit is connected with the first end of the second potentiometer. The circuit provided by the invention has advantages of simple structure, high detection sensitivity, and high reliability.
Description
technical field [0001] The invention relates to the field of temperature monitoring, in particular to a temperature alarm circuit for a natural gas flue-cured room. Background technique [0002] The flue-cured tobacco room is an indispensable basic equipment in the production of flue-cured tobacco. After being roasted and prepared in the flue-cured tobacco room, the unique color, aroma, taste and shape of the flue-cured tobacco will appear, and it will become a high-quality raw material that meets the needs of the cigarette industry. The basic principle is that after the tobacco leaves are heated, the water in the tobacco leaves is discharged, and the water is vaporized and then discharged out of the flue-curing room, so that the tobacco leaves are yellowed and dried. [0003] At present, the temperature control alarm in the flue-cured room is developing from analog to digital, and electronic from integration to intelligence and networking. Old-style mechanical temperature...
