What is the working principle of automatic weighing machine?

by admin

automatic weighing machine is composed of electronic components, weighing sensor, amplification circuit, AD conversion circuit, single chip microcomputer circuit, display circuit, keyboard circuit, communication interface circuit, regulated power supply circuit and other circuits. Workflow description: when the object is placed on the scale, the pressure is applied to the sensor, and the sensor deforms, so that the impedance changes. At the same time, the excitation voltage changes, and a changed analog signal is output

the signal is amplified by the amplification circuit and output to the analog-to-digital converter. It is converted into a digital signal convenient for processing and output to CPU operation control. The CPU outputs this result to the display according to keyboard commands and programs. Until this result is displayed. To understand the price of weighing machine, please click online customer service consultation

automatic weighing machine can be purchased from Casso company. Casso company attaches great importance to the cultivation of independent R & D ability and the construction of technical team. It has a technical team with independent R & D ability. The members of the technical team of the company have many years of experience in the development of testing equipment and have deep theoretical attainments and rich experience in the development of testing equipment, which ensures that the company can continuously launch products with higher technical content that meet the needs of customers

Step 1: feeding process
products enter the feeding conveyor, and the speed setting of the feeding conveyor is jointly determined according to the product spacing and the required speed, so as to ensure that only one product can be on the scale platform during the working process of the automatic weighing machine
Step 2: weighing process
when the product enters the weighing conveyor, the system identifies the product to be tested to enter the weighing area according to external signals, such as photoelectric switch signal or internal level signal. According to the running speed and length of the weighing conveyor, or according to the level signal, the system can determine the time when the product leaves the weighing conveyor. From the product entering the scale platform to leaving the scale platform, the weighing sensor will detect the signal, and the controller selects the signal in the signal stable area for processing, so as to obtain the weight of the product
Step 3: elimination process
when the controller obtains the weight signal of the product, the system will compare it with the preset weight range to eliminate the product. The elimination types will vary according to different applications, mainly including the following types:
1. Rejection of unqualified products
2. Remove overweight and underweight respectively, or transport them to different places.
