Through the optical sensor and the counting sensor, the running times and the main shaft speed of the centrifuge are monitored in real time. According to the preset stop conditions (such as running times, time or main shaft speed, etc.), the control system will judge whether to stop the centrifuge. When the centrifuge runs to the preset number of times or time, the control system will receive signals from the drum counting device or the main shaft detection mechanism. If the stop conditions are met, the control system will send a stop signal, cut off the power supply of the motor, and make the centrifuge gradually stop rotating.
