Electronic scale development plan

Electronic scale product description: The pressure sensor realizes piezoelectric conversion and converts pressure into electrical signals. After being amplified by a high-precision differential amplifier. It is input to the analog-to-digital converter and converted into a digital signal. The digital signal controls the encoding of the encoder to control the display of the digital tube.

Product features: The function of each module is single, and there is no complicated programming problem. When debugging the entire system, it is convenient to test each module and quickly find the problematic module. It is easier to make.

Electronic scale PCB structure description

1. Carrier: It is the weight receiving device commonly known as the weighing platform (pan). It should be able to contain the weight to be weighed. Its size, rigidity, shape and wear resistance should not be ignored.

2. Gravity introduction (transfer) device. This is an unobtrusive component that is very important and easily overlooked. It can be attached to the load carrier or the load cell. Its main function is to distribute on the weighing platform. The weight of this state is concentrated into a gravity equal to the weight of the weight, and the force point acts on the load cell, sometimes including some additional lever systems.
