There are many kinds of electronic scale products, including wireless data transmission and direct viewing according to the reading methods; According to the type of sensor, it can be divided into resistance type and capacitance type; According to the form of force transmission hook head, it can be divided into hook head hanging scale and hook head hanging scale; According to the power supply mode, it can be divided into wired hanging scales with limited power supply and wireless hanging scales with battery power supply; According to other ways, it can be divided into crane scale, monorail crane scale and portable crane scale. According to the application, it can also be called anti-heat and anti-magnetic hanging scales.

　　Model of electronic crane scale

　　There are two types of electronic hanging scales, one is wireless data transmission electronic hanging scale, and the other is direct-view electronic hanging scale.

　　Composition and structure of electronic crane scale

　　Electronic scale generally consists of mechanical bearing mechanism, weighing sensor, A/D conversion board, power supply, wireless transmitter and receiver and weighing display instrument.

　　Composition of Wireless Digital Transmission Electronic Hanging Scale

　　Wireless data transmission electronic hanging scale consists of a scale body and instruments. The scale body includes mechanical bearing mechanism, sensor, A/D board, wireless transmitter, power supply and shell, in which the mechanical bearing mechanism includes shackle, hook and pin shaft. In addition, in order to ensure the safety and reliability of the system, there are sensor protection devices.

　　Composition of direct-view electronic crane scale

　　Compared with the wireless digital electronic hanging scale, the biggest feature of the direct-view electronic hanging scale is that the instrument function is directly embedded in the scale body, and the digital display screen on the scale body reflects the weighed indication value.
