EBLL-90料流檢測開關,料流開關是利用微型馬達做驅動裝置，傳動軸與離合器相連接，當未接觸物料時，馬達正常運轉，當葉片接觸物料時，馬達停止轉動，檢測裝置輸出一接點信號，同時切斷電源停止轉動。當物料下降時葉片所受阻力消失，檢測裝置依靠扭力彈簧恢復到原始狀態。針對不同比重的物料扭力大小可以調節。 
廣泛應用于冶金、煤炭、水泥、鋼鐵等行業，尤其是在水泥倉、煤倉等使用環境惡劣的地方。

性能簡介：

適用于水泥、冶金、煤碳、飼料、糧食、鋼鐵、電廠等行業，特別是在導電性物料、物質屬性（狀態、濕度、介電常數、密度等）經常改變、大粉塵等物料的限位報警應用中表現出色，可用于固態物料的物位度監控，在水泥倉、煤倉、粉塵倉、灰倉等物位的監控中已經被大量使用。電機性能可靠；雙倍密封軸承可保證長時間連續運轉；油封設計可以防粉塵沿軸滲入；阻旋開關扭力穩定可靠,且扭力大小可以調節；阻旋開關的葉片承受過重負荷時，馬達回轉機構會自動打滑，保護不受損壞。

產品應用                                                       

冶金、化工、石油、電力、食品、造紙、煤炭、建材、醫藥等領域料位的報警和控制

塵、防爆等特殊環境

阻旋料位開關的工作原理是利用永磁電機帶動葉片旋轉，當被檢測物料上升至葉片位置時，葉片轉動受阻，將該阻力傳至接線盒內的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電源使葉片停止轉動。
當料位下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態，針對不同的物料比重調整彈簧拉力，比重大時調整彈簧拉力到強或zui強，反之則調整至弱或zui弱。
采用擺動式傳動系統。電機底座通過彈簧拉住，當系統沒有受阻時，電機轉動，帶動檢測葉片，檢測物料。檢測板受阻時，使主軸受阻而靜止，電機繼續運行，使電機底座拉動彈簧，壓下微動開關，發出有料信號，同時切斷電機電源，電機停止工作。當物位下降時檢板阻力消失，系統在彈簧的拉力下復位，微動開關恢復原始狀態，使電機轉動，同時發出無料信號。

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.
