Abstract. The article suggests a new method of automatic continuous monitoring of the level of loose building materials in the storage capacity, ensuring the efficiency and reliability of the automatic control system of the actuators. The method of level control is based on immersion in the set intervals of the measuring probe before it comes into contact with the surface of the bulk material. The automatic movement of the probe is measured by a device that determines the level of the material and provides a signal to the control system.
Key words: level of loose materials, kinematics of the measuring device, switching unit with synchronous electric motor, excitation coils of transformer displacement converters, control thyristors, switching relays.
