EBLL-90料流检测开关,料流开关是利用微型马达做驱动装置，传动轴与离合器相连接，当未接触物料时，马达正常运转，当叶片接触物料时，马达停止转动，检测装置输出一接点信号，同时切断电源停止转动。当物料下降时叶片所受阻力消失，检测装置依靠扭力弹簧恢复到原始状态。针对不同比重的物料扭力大小可以调节。 
广泛应用于冶金、煤炭、水泥、钢铁等行业，尤其是在水泥仓、煤仓等使用环境恶劣的地方。

产品应用                                                       

冶金、化工、石油、电力、食品、造纸、煤炭、建材、医药等领域料位的报警和控制

尘、防爆等特殊环境

阻旋料位开关的工作原理是利用永磁电机带动叶片旋转，当被检测物料上升至叶片位置时，叶片转动受阻，将该阻力传至接线盒内的检测装置，检测装置则向外输出一个开关信号，并切断电源使叶片停止转动。
当料位下降时，叶片阻力消失，检测装置便依靠弹簧的拉力恢复到原始状态，针对不同的物料比重调整弹簧拉力，比重大时调整弹簧拉力到强或zui强，反之则调整至弱或zui弱。
采用摆动式传动系统。电机底座通过弹簧拉住，当系统没有受阻时，电机转动，带动检测叶片，检测物料。检测板受阻时，使主轴受阻而静止，电机继续运行，使电机底座拉动弹簧，压下微动开关，发出有料信号，同时切断电机电源，电机停止工作。当物位下降时检板阻力消失，系统在弹簧的拉力下复位，微动开关恢复原始状态，使电机转动，同时发出无料信号。

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 rtain 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, ment plants, chemical plants, ports and other industries.

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 devi 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 devi 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, ment, steel and other industries, especially in the ment silo, coal bunker, etc.
Performan profile:
Applicable to the ment, 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 performan, and can be used for solid material level monitoring, the ment warehouse, coal, dust bin, ash warehouse and material level has been extensively used in monitoring. Reliable performan 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.
Resistan 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 resistan to terminal box testing devi, testing devi 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 resistan detection devi 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 resistan 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.
