Do you understand the working principle of the automatic weighing machine?
The automatic weighing machine is designed for powdery and fluid powder. It adopts floor-standing structure, small structure and convenient installation. Now it is one of the indispensable magic weapons of major factories. So, do you understand the working principle of the automatic weighing machine? Let me take a look at the working principle of the automatic weighing machine today.
Do you understand the working principle of the automatic weighing machine?
The automatic weighing machine is composed of electronic components, weighing sensors, amplifying circuits, AD conversion circuits, single-chip circuits, display circuits, keyboard circuits, communication interface circuits, and regulated power supply circuits. Workflow Description: When an object is placed on the weighing pan, pressure is applied to the sensor, which deforms, causing the impedance to change, and using the excitation voltage to change, outputting a varying analog signal. The signal is amplified by an amplifying circuit and output to an analog to digital converter. The digital signal converted into a convenient processing is output to the CPU arithmetic control. The CPU outputs this result to the display according to keyboard commands and programs. Until this result is shown.
Then how to install the dosing load cell loader? The load cell is part of the dosing device, the so-called load cell, the main function is to weigh the weight of the material above the dosing machine, although weighing The sensor is only an accessory for the dosing device, but its function cannot be ignored. Therefore, the installation of the dosing load cell is also very important, so what should be paid attention to when installing the dosing load cell? What about the problem?
The load cell of the dosing machine should be handled gently to avoid any vibration and impact, so as to avoid the large error of the load cell when outputting the signal. In the process of adjusting the level during the installation, it is necessary to ensure its base. The installation plane should be adjusted to the horizontal state by using the level. The purpose is to ensure that the force of the sensor is the same. It is also necessary to prevent chemical corrosion. Avoid exposure and rain during use. If the cable needs to be lengthened, it cannot be lengthened. Soldering at the joint when lengthening, and moisture-proof sealing; if it is to be used in high precision, it is necessary to preheat the load cell and instrument for 30 minutes, remember: each metering The loading direction of the load cell loader is determined, and we must load the load in this direction when we use it. Lateral forces, additional bending moments, and torque forces should be avoided as much as possible.
