DL-02 coal cut-off alarm

Installation precautions
1. The installation requirements should ensure that the blade is located away from the lower part of the feed inlet and the dead material area of the silo. To prevent material impact during use, a protective plate should be installed above the detection blade.
2. If an extended shaft is installed vertically, a protective sleeve should be installed or the position of the blades and flexible shaft should not be directly hit by the material. When measuring multiple positions, the distance should be appropriately widened to avoid the entanglement of flexible shafts.
3. To avoid the infiltration of rainwater into the outdoor environment, when installing on the side, the outlet should be vertically downward and the cover should be tightened. If possible, consider installing a rain cover when installing vertically.

Product Features

1. Using contact measurement, the results are true, accurate, and reliable; It can be installed horizontally, diagonally, and vertically, making it easy to install and use.
2. Anti interference, ready to use: Due to the absence of complex electronic components and amplification circuits inside, it is not affected by any electromagnetic wave interference and can be used for a long time after installation, debugging, and maintenance.
3. Anti shake performance design: No erroneous signals will be emitted even during material flow.
4. Material level display function: using long-life brightness indicator lights, the material level display is intuitive and convenient.
5. Dual protection function: Overload protection function prevents the blades from being damaged by excessive external forces and the motor; The automatic protection function prevents the level indicator from working when the rotation of the material blades in the silo is obstructed, protecting the motor and effectively extending its service life.

DL-02 material cut-off alarm

Adopting a swing transmission system. The motor base is held by a spring, and when the system is unobstructed, the motor rotates to drive the detection blades and detect materials. When the detection board is obstructed, the spindle is obstructed and comes to a stop. The motor continues to run, causing the motor base to pull the spring, press the micro switch, and send out a material signal. At the same time, the motor power is cut off, and the motor stops working. When the level drops, the resistance of the inspection plate disappears, and the system resets under the tension of the spring. The micro switch returns to its original state, causing the motor to rotate and emitting a no material signal.

DL-02 material cut-off alarmIt is achieved by connecting the Weidong shaft with the clutch. When the material is not in contact, the motor maintains normal operation. When the blades come into contact with the material, the motor stops rotating, and the mechanism simultaneously outputs a signal to measure the material level or blockage signal of the silo.
