Abstract

The invention discloses a portable electronic scale which comprises a plastic machine shell and a stainless steel scale tray embedded on the opening face of the plastic machine shell. The portable electronic scale can be connected with an external printer through a USB interface. The portable electronic scale comprises a hardware system which is composed of a main control chip, a weighing sensor, an amplification circuit, an A/D converter, an LCD screen and a USB interface module, wherein the weighing sensor, the amplification circuit, the A/D converter, the LCD screen and the USB interface module are electrically connected with the main control chip, and the weighing sensor is an electromagnetic force balance sensor. Through the above mode, the portable electronic scale is small in size and accurate and quick in measurement, integrates the function of weighing and the function of price calculation, can be connected with external equipment, and provides the function of printing or data transmission.

Description

technical field [0001] The invention relates to the field of balance instruments, in particular to a portable electronic balance. Background technique [0002] With the development of measurement technology and electronic technology, traditional weighing devices such as steelyards, platform scales, and scales with purely mechanical structures are gradually eliminated. Electronic weighing devices are favored by people for their accuracy, speed, convenience, and intuitive display. . [0003] Electronic weighing devices are roughly divided into electronic balances, electronic weighing scales, electronic weighing and counting scales, heavy electronic hanging scales, electronic floor scales, axle load meters, and professional scales. Electronic balances include ordinary electronic balances, precision electronic Balances and special balances, among which special balances include code step scales for the textile and printing industry, high-precision, high-stability jewelry scales....
