MCK880E weighing display controller is a microcomputer which provides automatic quantitative control for packaging machines of building materials, chemical industry, grain, etc. The machine is controlled by a single chip microcomputer and is an intelligent instrument integrating weighing control. With unique anti-interference, the MCK880E weighing display controller can be used for a long time in bad environment to accept the analog signal output by the sensor, and after the internal collection signal processing, calculate and display the weight value of the material in the weighing body. The weight value of the material in the symmetrical body is compared with the set value. If the weight value reaches the set value, the controller number is given to the execution equipment (such as the action of thick and thin flow feeding, unloading, bag dropping, etc.).
