Abstract
The utility model discloses a divided high-temperature-resistant electronic scale which comprises an article bearing device and a display device. The article bearing device comprises a pressure sensor, a pedestal and an article bearing table. The display device comprises a display screen, an amplification circuit, an A/D conversion circuit, a single-chip microcomputer, a keypad circuit, a display circuit and a power supply circuit. The article bearing table is disposed on the pedestal. The article bearing device and the display device are divided yet connected through a signal line. A pressure signal of a measured article is acquired by the pressure sensor, and then is amplified by the amplification circuit and then is input into the A/D conversion circuit for conversion into a digital signal, and then the digital signal is input into the single-chip microcomputer; after computation and processing by the single-chip microcomputer, a mass value of the measured article is obtained and is input into the display circuit which then controls the display screen to display the mass value. The divided high-temperature-resistant electronic scale can be used for measuring mass change situations of the measured article when alcohol or other heat sources are in combustion.
