Overview: 
 ● The machine is used to detect belt conveyor transport of materials, may issue a load operation signal. If sprinkler connection, enabling the automatic sprinkler function of the material. This unit can also be applied to the tape machine to run 
 Technical parameters

 Structural features 
 ● For the wide tape, when used with high-speed door frame installation, see figure; 
 ● If the tape is relatively narrow, with a speed lower arm bracket can be used; 
 ● the use of hammer contact with the material, reducing the direct material impact on the detector to extend the service life; 
 ● Refer to Figure 1, if the choice arm bracket, the arrow pointing at the broken beams, beams with junction plus a cable-stayed arm angle, as shown in dotted line. 
 Installation and adjustment 
 ● The door bracket installation, the sensor head fixed on the beam; 
 ● a high degree of visual field conditions to determine the hammer; 
 ● The device switching angle of 20 °, the inclination of a tape machine may be appropriate to adjust the installation angle; 
 ● arm mount can be used to refer to-door installation; 
 ● LL-Ⅱ type installed in the tape, and sinking under the largest part; 
 ● no load, the adhesive tape to maintain contact with the trolley; 
 ● regularly remove dust and maintain flexible and comfortable touch-round action; 
 Works 

 LL-Ⅰ-type material flow detection device using the material in contact with the drop hammer test method. When the tape transport materials, and materials to promote the ball with the arm to the side of the offset, if the offset angle greater than 20 °, the internal switch and the output a switching signal. 
 LL-Ⅱ type uses a load-type detection. Operation of the tape is loaded, tape sink, installed in the tape following the detection of pressure and touch wheel to the machine by turning lever limit switch operation, the output switching signal to achieve detection.
