　　Ebll-90 material flow detection switch, feed flow switch for conveying materials on the conveyor belt, use the blades at the front end for testing. As the blade is tilted to a certain Angle, the internal microswitch is compressed to make the material flow as a signal to output. The material flow detection switch is used to detect the instantaneous state of conveying materials on the conveyor belt. It is widely used in steel mills, thermal power plants, cement plants, chemical plants, ports and other industries.

　　Ebll-90 flow detection switch specifications.

　　Ebll-90 material flow detection switch manufacturers.

　　Technical specifications

　　Output: 1C contact AC250V 5A (resistive load)

　　Action Angle: 20 ° (for from the perspective of the direction of blade, in clockwise direction or in a counterclockwise direction as the direction of the movement, please add to specify)

　　Material: body shell, flange aluminum magnesium alloy shaft, blade SUS304 wear rubber.

　　Protection grade: IP65.

　　Product features

　　Strong cast aluminum shell, electrostatic anticorrosion coating suitable for the installation of harsh industrial and mining environment.

　　Suitable for all kinds of wide belt mounting.

　　The slurry rubber section can be replaced periodically according to the use condition.

　　Simple structure, no maintenance.

　　Large capacity mini contact.

　　EBLL - 90 flow detection switch, material flow switch is the use of the micro motor to drive, drive shaft connected to the clutch, when not contact materials, motor function, when the blade contact materials, motor stop running, detection device contact of output signal, at the same time to cut off the power to stop turning. When the material falls, the blade is removed, and the detection device is returned to the original state by the torsion spring. The torque size can be adjusted for different weights.

　　Ebll-90 flow detection switch is widely used in metallurgy, coal, cement, steel and other industries, especially in the cement silo, coal bunker, etc.

　　Performance profile:

　　Applicable to the cement, metallurgy, coal, feed, food, steel, power plants and other industries, especially in conductive materials, material properties (status, humidity, dielectric constant and density, etc.) change often, dust and other materials limit alarm application performance, and can be used for solid material level monitoring, the cement warehouse, coal, dust bin, ash warehouse and material level has been extensively used in monitoring. Reliable performance of imported motor; Double seal bearing can ensure continuous operation for a long time; Professional oil seal design can prevent dust from infiltration along the axis; The torsion switch is stable and reliable, and the torque size can be adjusted. When the blade of the choke switch is overloaded, the motor slewing mechanism will automatically slip and protect against damage.

　　The product application

　　Alarm and control of materials in metallurgy, chemical industry, petroleum, power, food, paper, coal, building materials, medicine, etc.

　　High dust, explosion-proof and other special environment.

　　Resistance spin material level switch working principle is the use of permanent magnet motor drive the blades rotating, when tested material rise to leaf position, blade rotation is blocked, the resistance to terminal box testing device, testing device is to output a switch signals, and to cut off the power supply to rotate the blade to stop.

　　Disappear, when material level drops, blade resistance detection device will rely on the tension of the spring back to its original state, according to different material proportion adjusting spring tension, adjust the spring tension than when big to strong or the strongest, the opposite adjustment to the weak or the weakest.

　　Ebll-90 material flow detection switch, the feed flow switch adopts the swing transmission system. The motor base is held by the spring, and when the system is not blocked, the motor turns, driving the detection of the blade and testing the material. Test board is blocked, make main shaft blocked and stationary, motor continues to run, pull the spring makes the motor base, press the micro switch, signal with material, cut off the electrical power supply at the same time, the motor stop working. When the object position drops, the resistance of the inspection plate disappears, the system is reset under the tension of the spring, the micro switch is restored to the original state, and the motor turns and sends out the blanking signal.
